This is a + propotional value. What that means is that if there + are two users logged in, each with an equal number of + shares, then they will get equal CPU bandwidth. Another + example would be, if User A has shares = 1024 and user + B has shares = 2048, User B will get twice the CPU + bandwidth user A will.

Given that driver is built on parport, the -parallel port abstraction layer, this driver is architecture-independent. - -It can also be used with another device plugged on the same port (such as a -ZIP drive).
