Remove the bios emulator from MAI board.

The bios emulator in the MAI board can not pass compile
and have a lot of crap in it. remove it and will have a
clean and small bios emulator in the drivers directory
which can be uesed for every board.

-NOTE:   Scan codes in the event library are not really hardware scan codes,

-when        - Time that the event occurred in milliseconds since startup
-where_x     - X coordinate of the mouse cursor location at the time of the event
-	      (in screen coordinates). For joystick events this represents
-	      the position of the first joystick X axis.
-where_y     - Y coordinate of the mouse cursor location at the time of the event
-	      (in screen coordinates). For joystick events this represents
-	      the position of the first joystick Y axis.
-relative_x  - Relative movement of the mouse cursor in the X direction (in
-	      units of mickeys, or 1/200th of an inch). For joystick events
-	      this represents the position of the second joystick X axis.
-relative_y  - Relative movement of the mouse cursor in the Y direction (in

-	      this represents the position of the second joystick Y axis.
-message     - Event specific message for the event. For use events this can be

-	      EVT_asciiCode, EVT_scanCode and EVT_repeatCount macros to extract
-	      this information from the message field. For mouse events this
-	      contains information about which button was pressed, and will be a
-	      combination of the flags defined by the EVT_eventMouseMaskType
-	      enumeration. For joystick events, this conatins information
-	      about which buttons were pressed, and will be a combination of
-	      the flags defined by the EVT_eventJoyMaskType enumeration.
-modifiers   - Contains additional information about the state of the keyboard
-	      shift modifiers (Ctrl, Alt and Shift keys) when the event
-	      occurred. For mouse events it will also contain the state of
-	      the mouse buttons. Will be a combination of the values defined

-REMARKS:
-This enumeration defines the type values passed to the PM_agpReservePhysical
-function, to define how the physical memory mapping should be handled.
-
-The PM_agpUncached type indicates that the memory should be allocated as
-uncached memory.
-
-The PM_agpWriteCombine type indicates that write combining should be enabled
-for physical memory mapping. This is used for framebuffer write combing and
-speeds up direct framebuffer writes to the memory.
-
-The PM_agpIntelDCACHE type indicates that memory should come from the Intel
-i81x Display Cache (or DCACHE) memory pool. This flag is specific to the
-Intel i810 and i815 controllers, and should not be passed for any other
-controller type.

-*               functions, both in 16 bit and 32 bit modes. Note however that

-/*---------------------------------------------------------------------------
- * Set of debugging macros used by the libraries. If the debug flag is
- * set, they are turned on depending on the setting of the flag. User code
- * can override the default functions called when a check fails, and the
- * MGL does this so it can restore the system from graphics mode to display
- * an error message. These functions also log information to the
- * scitech.log file in the root directory of the hard drive when problems
- * show up.
- *
- * If you set the value of CHECKED to be 2, it will also enable code to
- * insert hard coded debugger interrupt into the source code at the line of
- * code where the check fail. This is useful if you run the code under a
- * debugger as it will break inside the debugger before exiting with a
- * failure condition.
- *
- * Also for code compiled to run under Windows, we also call the
- * OutputDebugString function to send the message to the system debugger
- * such as Soft-ICE or WDEB386. Hence if you get any non-fatal warnings you
- * will see those on the debugger terminal as well as in the log file.

-;* Language:    NetWide Assembler (NASM) or Turbo Assembler (TASM)
-;* Environment: Any Intel Environment
-;*
-;* Description: Macros to provide memory model independant assembly language
-;*              module for C programming. Supports the large and flat memory
-;*              models.
-;*
-;*              The defines that you should use when assembling modules that
-;*              use this macro package are:
-;*
-;*                  __LARGE__   Assemble for 16-bit large model
-;*                  __FLAT__    Assemble for 32-bit FLAT memory model
-;*                  __NOU__     No underscore for all external C labels
-;*                  __NOU_VAR__ No underscore for global variables only
-;*
-;*              The default settings are for 16-bit large memory model with
-;*              leading underscores for symbol names.
-;*
-;*              The main intent of the macro file is to enable programmers
-;*              to write _one_ set of source that can be assembled to run
-;*              in either 16 bit real and protected modes or 32 bit
-;*              protected mode without the need to riddle the code with
-;*              'if flatmodel' style conditional assembly (it is still there
-;*              but nicely hidden by a macro layer that enhances the
-;*              readability and understandability of the resulting code).
-;*
-;****************************************************************************
-
-; Include the appropriate version in here depending on the assembler. NASM
-; appears to always try and parse code, even if it is in a non-compiling
-; block of a ifdef expression, and hence crashes if we include the TASM
-; macro package in the same header file. Hence we split the macros up into
-; two separate header files.

-DESCRIPTION:
-Parse the command line for specific options
-
-HEADER:
-cmdline.h
-
-PARAMETERS:
-argc        - Value passed to program through argc variable
-argv        - Pointer to the argv array passed to the program
-format      - A string representing the expected format of the command line
-argument    - Pointer to optional argument on command line
-
-RETURNS:
-Character code representing the next option parsed from the command line by
-getcmdopt. Returns ALLDONE (-1) when there are no more parameters to be parsed
-on the command line, PARAMETER (-2) when the argument being parsed is a
-parameter and not an option switch and lastly INVALID (-3) if an error
-occured while parsing the command line.
-
-REMARKS:
-Function to parse the command line option switches in UNIX System V style.
-When getcmdopt is called, it returns the character code of the next valid
-option that is parsed from the command line as specified by the Format
-string. The format string should be in the following form:
-
-    "abcd:e:f:"
-
-where a,b and c represent single switch style options and the character
-code returned by getcmdopt is the only value returned. Also d, e and f
-represent options that expect arguments immediately after them on the
-command line. The argument that follows the option on the command line is
-returned via a reference in the pointer argument. Thus a valid command line
-for this format string might be:
-
-    myprogram -adlines -b -f format infile outfile
-
-where a and b will be returned as single character options with no argument,
-while d is returned with the argument lines and f is returned with the
-argument format.
-
-When getcmdopt returns with PARAMETER (we attempted to parse a paramter, not
-an option), the global variable NextArgv will hold an index in the argv
-array to the argument on the command line AFTER the options, ie in the
-above example the string 'infile'. If the parameter is successfully used,
-NextArgv should be incremented and getcmdopt can be called again to parse any
-more options. Thus you can also have options interspersed throught the
-command line. eg:
-
-    myprogram -adlines infile -b outfile -f format
-
-can be made to be a valid form of the above command line.

-*                     DLL's linked by another compiler.

-* Description:  Implementation for the OS Portability Manager Library, which
-*               contains functions to implement OS specific services in a
-*               generic, cross platform API. Porting the OS Portability
-*               Manager library is the first step to porting any SciTech
-*               products to a new platform.

-DESCRIPTION:
-Split a full pathname into components.
-
-HEADER:
-pmapi.h
-
-PARAMETERS:
-path    - Full path to split
-drive   - Drive component for path
-dir     - Directory component for path
-name    - Filename component for path
-ext     - Extension component for path
-
-RETURNS:
-Flags indicating what components were parsed.
-
-REMARKS:
-Function to split a full pathmame into separate components in the form
-
-    X:\DIR\SUBDIR\NAME.EXT
-
-and splits path into its four components. It then stores those components
-in the strings pointed to by drive, dir, name and ext. (Each component is
-required but can be a NULL, which means the corresponding component will be
-parsed but not stored).
-
-The maximum sizes for these strings are given by the constants PM_MAX_DRIVE
-and PM_MAX_PATH. PM_MAX_DRIVE is always 4, and PM_MAX_PATH is usually at
-least 256 characters. Under Unix the dir, name and ext components may be
-up to the full path in length.

-malloc  - Pointer to new malloc routine to use
-calloc  - Pointer to new caalloc routine to use
-realloc - Pointer to new realloc routine to use
-free    - Pointer to new free routine to use
-
-REMARKS:
-Tells the PM library to use a set of user specified memory allocation
-routines instead of using the normal malloc/calloc/realloc/free standard
-C library functions. This is useful if you wish to use a third party
-debugging malloc library or perhaps a set of faster memory allocation
-functions with the PM library, or any apps that use the PM library (such as
-the MGL). Once you have registered your memory allocation routines, all
-calls to PM_malloc, PM_calloc, PM_realloc and PM_free will be revectored to
-your local memory allocation routines.
-
-This is also useful if you need to keep track of just how much physical
-memory your program has been using. You can use the PM_availableMemory
-function to find out how much physical memory is available when the program
-starts, and then you can use your own local memory allocation routines to
-keep track of how much memory has been used and freed.
-
-NOTE: This function should be called right at the start of your application,
-      before you initialise any other components or libraries.
-
-NOTE: Code compiled into Binary Portable DLL's and Drivers automatically
-      end up calling these functions via the BPD C runtime library.

-;*
-;* Language:    NASM or TASM Assembler
-;* Environment: IBM PC (MS DOS)
-;*
-;* Description: Uses the 8253 timer and the BIOS time-of-day count to time
-;*              the performance of code that takes less than an hour to
-;*              execute.
-;*
-;*              The routines in this package only works with interrupts
-;*              enabled, and in fact will explicitly turn interrupts on
-;*              in order to ensure we get accurate results from the timer.
-;*
-;*  Externally 'C' callable routines:
-;*
-;*  LZ_timerOn:     Saves the BIOS time of day count and starts the
-;*                  long period Zen Timer.
-;*
-;*  LZ_timerLap:    Latches the current count, and keeps the timer running
-;*
-;*  LZ_timerOff:    Stops the long-period Zen Timer and saves the timer
-;*                  count and the BIOS time of day count.
-;*
-;*  LZ_timerCount:  Returns an unsigned long representing the timed count
-;*                  in microseconds. If more than an hour passed during
-;*                  the timing interval, LZ_timerCount will return the
-;*                  value 0xFFFFFFFF (an invalid count).
-;*
-;*  Note:   If either more than an hour passes between calls to LZ_timerOn
-;*          and LZ_timerOff, an error is reported. For timing code that takes
-;*          more than a few minutes to execute, use the low resolution
-;*          Ultra Long Period Zen Timer code, which should be accurate
-;*          enough for most purposes.
-;*
-;*  Note:   Each block of code being timed should ideally be run several
-;*          times, with at least two similar readings required to
-;*          establish a true measurement, in order to eliminate any
-;*          variability caused by interrupts.
-;*
-;*  Note:   Interrupts must not be disabled for more than 54 ms at a
-;*          stretch during the timing interval. Because interrupts are
-;*          enabled, key, mice, and other devices that generate interrupts
-;*          should not be used during the timing interval.
-;*
-;*  Note:   Any extra code running off the timer interrupt (such as
-;*          some memory resident utilities) will increase the time
-;*          measured by the Zen Timer.
-;*
-;*  Note:   These routines can introduce inaccuracies of up to a few
-;*          tenths of a second into the system clock count for each
-;*          code section being timed. Consequently, it's a good idea to
-;*          reboot at the conclusion of timing sessions. (The
-;*          battery-backed clock, if any, is not affected by the Zen
-;*          timer.)
-;*
-;*  All registers and all flags are preserved by all routines, except
-;*  interrupts which are always turned on

-;

-;
-; NOTE: This routine switches to a local stack before calling any C code,

-*               generic, cross platform API. Porting the OS Portability
-*               Manager library is the first step to porting any SciTech
-*               products to a new platform.

-
-PARAMETERS:
-userEventFilter - Address of user supplied event filter callback
-
-REMARKS:
-This function allows the application programmer to install an event filter
-callback for event handling. Once you install your callback, the MGL
-event handling routines will call your callback with a pointer to the
-new event that will be placed into the event queue. Your callback can the
-modify the contents of the event before it is placed into the queue (for
-instance adding custom information or perhaps high precision timing
-information).
-
-If your callback returns FALSE, the event will be ignore and will not be
-posted to the event queue. You should always return true from your event
-callback unless you plan to use the events immediately that they are
-recieved.
-
-Note:   Your event callback may be called in response to a hardware
-	interrupt and will be executing in the context of the hardware
-	interrupt handler under MSDOS (ie: keyboard interrupt or mouse
-	interrupt). For this reason the code pages for the callback that
-	you register must be locked in memory with the PM_lockCodePages
-	function. You must also lock down any data pages that your function
-	needs to reference as well.
-
-Note:   You can also use this filter callback to process events at the
-	time they are activated by the user (ie: when the user hits the
-	key or moves the mouse), but make sure your code runs as fast as
-	possible as it will be executing inside the context of an interrupt
-	handler on some systems.

-; Hardware interrupt handler for the timer interrupt, to dispatch control
-; to high level C based subroutines. We save the state of all registers
-; in this routine, and switch to a local stack. Interrupts are *off*
-; when we call the user code.
-;
-; NOTE: This routine switches to a local stack before calling any C code,
-;       and hence is _not_ re-entrant. Make sure your C code executes as
-;       quickly as possible, since a timer overrun will simply hang the
-;       system.

-; If we enable interrupts and call into any C based interrupt handling code,

-; code below takes care of this housekeeping for us (see Undocumented NT for
-; details). If we don't do this housekeeping and interrupts are enabled,
-; the kernel will become very unstable and crash within 10 seconds or so.

-PARAMETERS:
-func        - Helper device driver function to call
-
-RETURNS:
-First return value from the device driver in parmsOut[0]
-
-REMARKS:
-Function to open our helper device driver, call it and close the file
-handle. Note that we have to open the device driver for every call because
-of two problems:
-
- 1. We cannot open a single file handle in a DLL that is shared amongst
-    programs, since every process must have it's own open file handle.
-
- 2. For some reason there appears to be a limit of about 12 open file

-*               generic, cross platform API. Porting the OS Portability
-*               Manager library is the first step to porting any SciTech
-*               products to a new platform.

-with a different handler (the MGL for instance overrides this and replaces
-it with a handler that does an MGL_exit() before terminating the application
-so that it will clean up correctly.

-tm  - Timer object to start timing with
-
-REMARKS:
-Starts the Long Period Zen Timer counting. Once you have started the timer,
-you can stop it with LZTimerOff or you can latch the current count with
-LZTimerLap.
-
-The Long Period Zen Timer uses a number of different high precision timing
-mechanisms to obtain microsecond accurate timings results whenever possible.
-The following different techniques are used depending on the operating
-system, runtime environment and CPU on the target machine. If the target
-system has a Pentium CPU installed which supports the Read Time Stamp
-Counter instruction (RDTSC), the Zen Timer library will use this to
-obtain the maximum timing precision available.
-
-Under 32-bit Windows, if the Pentium RDTSC instruction is not available, we
-first try to use the Win32 QueryPerformanceCounter API, and if that is not
-available we fall back on the timeGetTime API which is always supported.
-
-Under 32-bit DOS, if the Pentium RDTSC instruction is not available, we
-then do all timing using the old style 8253 timer chip. The 8253 timer
-routines provide highly accurate timings results in pure DOS mode, however
-in a DOS box under Windows or other Operating Systems the virtualization
-of the timer can produce inaccurate results.
-
-Note: Because the Long Period Zen Timer stores the results in a 32-bit
-      unsigned integer, you can only time periods of up to 2^32 microseconds,
-      or about 1hr 20mins. For timing longer periods use the Ultra Long
-      Period Zen Timer.

-system provides, but with enough granularity to time longer periods of
-time than the Long Period Zen Timer. Note that the resolution of the timer
-ticks is not constant between different platforms, and you should use the
-ULZTimerResolution function to determine the number of seconds in a single
-tick of the timer, and use this to convert the timer counts to seconds.
-
-Under 32-bit Windows, we use the timeGetTime function which provides a
-resolution of 1 millisecond (0.001 of a second). Given that the timer
-count is returned as an unsigned 32-bit integer, this we can time intervals
-that are a maximum of 2^32 milliseconds in length (or about 1,200 hours or
-50 days!).
-
-Under 32-bit DOS, we use the system timer tick which runs at 18.2 times per
-second. Given that the timer count is returned as an unsigned 32-bit integer,
-this we can time intervals that are a maximum of 2^32 * (1/18.2) in length
-(or about 65,550 hours or 2731 days!).

-This is a preliminary version of a VGA softbooter for LINUX.
-
-It makes use of the of the vm86() call and is therefore only
-usable on ix86 systems.
-There are plans to port this program to use a x86 emulator
-like x86emu. Also it may be ported to other operating systems.
-
-So far it has been tested on a small number of cards. It might
-well be that it will fail on your card.
-
-If you need to make modifications to the programs to be able
-to boot your card please let the author know.
-
-So far there is no command line interface. All options need
-to be hardcoded. You can do this by editing debug.h. You can
-turn on a bunch of debug output. Other options allow you to
-boot the primary card (CONFIG_ACTIVE_DEVICE), save the bios
-to a file (SAVE_BIOS), and map the original system bios
-(MAP_SYS_BIOS).
-
-The author wants to thank
- Hans Lermen   (dosemu)
- and
- Kendall Bennett (x86emu)
-for their support.
-
-Parts of the code - especially in v86.c and io.c - are based on code
-taken from dosemu. Parts of the code in int.c are based on code taken
-from x86emu

-What I had to do to make cards happy:
-
-1. Tseng ET4000 W32P
-This card wants to call the original system BIOS video routines.
-It sets the int 0x42 vector to F000:F065, the entry point to the
-system bios video routines. 
-CAVE: don't catch int 0x42 and use the vbios int 0x10 routines. 
-At early stage during initialization they call int 0x42. This 
-causes an infinite loop.
-
-2. ATi Mach64 Rage IIc AGP
-This card does similar things like the Tseng ET4000 W32P.
-However it doesn't have the problem with the ininite loop.
-
-3. Elsa Victory II-A16 AGP Banshee
-This card is very clever: It knows it is an AGP card. Therefore
-it knows it is behind a PCI-PCI bridge. It also knows that noone
-else is behind this bridge. Therefore it start reprogramming the
-bridge! For this it assumes the AGP bridge is on bus 1.
-
-4. Elsa Gloria Synergy 8 ViVo AGP PM2
-This card likes to see a complete interrupt vector table. If
-we fill this table with 0 the VBIOS detects this and quits 
-initialization.
-
-5. Dimond Viper 330 AGP NVIDIA Riva 128.
-This card has a similar problem like the Elsa Gloria. It wants
-to read the system BIOS date at 0xffffd.
-
-6. Matrox Mystique PCI 
-This card reads the IO port 0x62. If it doesn't like what it sees
-it loops forever. To keep the card happy put 0xfc into 0xffffe.
-This location holds the system model id. 0xfc means IBM-AT.
- One can make an interesting observation: this card likes to know 
-with whom it has to share the system. Therefore it accesses PCI 
-config space of all the other cards. It does this bypassing the 
-PCI BIOS by reading the PCI access ports directly.
-
-7. Matrox G100 AGP
-This card has the same problem as the Mystique. 
-
-Apperantly this works now. However not all combinations of cards are
-checked, yet.
-
-Further notes:
-the IO register 0x42-0x43 as well as 0x61-0x63 are of special interest
-for many graphic cards. They should be emulated.
-The so called "Industry Standard BIOS Entry Points" to int 0x42 (0xFF065)
-and to int 0x1a (0xFFE6E) should be filled with useful code. This code
-needs to return as if it was called as int.
-The subvendor ID PCI registers might cause problems. On some chipsets
-they are programmed in a non-obivous non-PCI conformant way.
-V_Bioses are seen to modify the following int:
-0x10 (default video), 0x1f(font table), 0x42(copy of default video), 
-0x43 (??), 0x6d (copy of default video - same as 0x10?)
-
-TODO:
-Int 0x6d needs to be done.
-All interrupts where there is no default industry standard entry point
-should point to an unused location in the 0xF000 segmant (possibly 
-0xF0000). This way they could be trapped. A trap handler for
-a. int 0x42 and int 0x1a needs to be implemented.
-The default "industry entry point" for video and PCI (0xFFE6E) should
-also be implemented. (any others?) They should either be routed to
-int 0x42(0x6d?) (video) and 0x1A (PCI) or some other interrupts to
-trap them. Mapping of system bios might not be a good idea. Maybe
-the system bios area should just be filled with "hlt" to trap any
-access there.
-Handling of timer IO registers 0x42, 0x43 and IO registers 0x61, 0x62.
-
-Find documentation:
-- on interrupt vector table
-- on industry standard entry points to the system bios
-- on IO registers 0x61 and 0x62

-whether the access is relative to DS or SS.  That is the function of the
-cpu-state-varible M.x86.mode. There are several potential states:
-
-	repe prefix seen  (handled elsewhere)
-	repne prefix seen  (ditto)
-
-	cs segment override
-	ds segment override
-	es segment override
-	fs segment override
-	gs segment override
-	ss segment override

-* Language:		ANSI C
-* Environment:	Any
-* Developer:    Kendall Bennett
-*
-* Description:  This file includes subroutines to implement the decoding
-*               and emulation of all the x86 processor instructions.
-*
-* There are approximately 250 subroutines in here, which correspond
-* to the 256 byte-"opcodes" found on the 8086.  The table which
-* dispatches this is found in the files optab.[ch].
-*
-* Each opcode proc has a comment preceeding it which gives it's table
-* address.  Several opcodes are missing (undefined) in the table.
-*
-* Each proc includes information for decoding (DECODE_PRINTF and
-* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
-* functions (START_OF_INSTR, END_OF_INSTR).
-*
-* Many of the procedures are *VERY* similar in coding.  This has
-* allowed for a very large amount of code to be generated in a fairly
-* short amount of time (i.e. cut, paste, and modify).  The result is
-* that much of the code below could have been folded into subroutines
-* for a large reduction in size of this file.  The downside would be
-* that there would be a penalty in execution speed.  The file could
-* also have been *MUCH* larger by inlining certain functions which
-* were called.  This could have resulted even faster execution.  The
-* prime directive I used to decide whether to inline the code or to
-* modularize it, was basically: 1) no unnecessary subroutine calls,
-* 2) no routines more than about 200 lines in size, and 3) modularize
-* any code that I might not get right the first time.  The fetch_*
-* subroutines fall into the latter category.  The The decode_* fall
-* into the second category.  The coding of the "switch(mod){ .... }"
-* in many of the subroutines below falls into the first category.
-* Especially, the coding of {add,and,or,sub,...}_{byte,word}
-* subroutines are an especially glaring case of the third guideline.
-* Since so much of the code is cloned from other modules (compare
-* opcode #00 to opcode #01), making the basic operations subroutine
-* calls is especially important; otherwise mistakes in coding an
-* "add" would represent a nightmare in maintenance.

-* Language:		ANSI C

-* Developer:    Kendall Bennett
-*
-* Description:  This file contains the code to implement the primitive
-*				machine operations used by the emulation code in ops.c
-*
-* Carry Chain Calculation
-*
-* This represents a somewhat expensive calculation which is
-* apparently required to emulate the setting of the OF and AF flag.
-* The latter is not so important, but the former is.  The overflow
-* flag is the XOR of the top two bits of the carry chain for an
-* addition (similar for subtraction).  Since we do not want to
-* simulate the addition in a bitwise manner, we try to calculate the
-* carry chain given the two operands and the result.
-*
-* So, given the following table, which represents the addition of two
-* bits, we can derive a formula for the carry chain.
-*
-* a   b   cin   r     cout
-* 0   0   0     0     0
-* 0   0   1     1     0
-* 0   1   0     1     0
-* 0   1   1     0     1
-* 1   0   0     1     0
-* 1   0   1     0     1
-* 1   1   0     0     1
-* 1   1   1     1     1
-*
-* Construction of table for cout:
-*
-* ab
-* r  \  00   01   11  10
-* |------------------
-* 0  |   0    1    1   1
-* 1  |   0    0    1   0
-*
-* By inspection, one gets:  cc = ab +  r'(a + b)
-*
-* That represents alot of operations, but NO CHOICE....
-*
-* Borrow Chain Calculation.
-*
-* The following table represents the subtraction of two bits, from
-* which we can derive a formula for the borrow chain.
-*
-* a   b   bin   r     bout
-* 0   0   0     0     0
-* 0   0   1     1     1
-* 0   1   0     1     1
-* 0   1   1     0     1
-* 1   0   0     1     0
-* 1   0   1     0     0
-* 1   1   0     0     0
-* 1   1   1     1     1
-*
-* Construction of table for cout:
-*
-* ab
-* r  \  00   01   11  10
-* |------------------
-* 0  |   0    1    0   0
-* 1  |   1    1    1   0
-*
-* By inspection, one gets:  bc = a'b +  r(a' + b)

-* Description:  Program to validate the x86 emulator library for
-*               correctness. We run the emulator primitive operations
-*               functions against the real x86 CPU, and compare the result
-*               and flags to ensure correctness.
-*
-*               We use inline assembler to compile and build this program.
