It tells you just enough - to know that you really don't want to learn how to program the chip. - - The original device probe code was stolen from ps2esdi.c - - Known Problems: - Since most of the code was stolen from ni52.c, you'll run across the - same bugs in the 0.62 version of ni52.c, plus maybe a few because of - the 3c523 idiosynchacies. The 3c523 has 16K of RAM though, so there - shouldn't be the overrun problem that the 8K ni52 has. - - This driver is for a 16K adapter. It should work fine on the 64K - adapters, but it will only use one of the 4 banks of RAM. Modifying - this for the 64K version would require a lot of heinous bank - switching, which I'm sure not interested in doing. If you try to - implement a bank switching version, you'll basically have to remember - what bank is enabled and do a switch every time you access a memory - location that's not current. You'll also have to remap pointers on - the driver side, because it only knows about 16K of the memory. - Anyone desperate or masochistic enough to try? - - It seems to be stable now when multiple transmit buffers are used. I - can't see any performance difference, but then I'm working on a 386SX. - - Multicast doesn't work. It doesn't even pretend to work. Don't use - it. Don't compile your kernel with multicast support. I don't know - why. - - Features: - This driver is useable as a loadable module. If you try to specify an - IRQ or a IO address (via insmod 3c523.o irq=xx io=0xyyy), it will - search the MCA slots until it finds a 3c523 with the specified - parameters. - - This driver does support multiple ethernet cards when used as a module - (up to MAX_3C523_CARDS, the default being 4) - - This has been tested with both BNC and TP versions, internal and - external transceivers.
