Not fast enough is typical a problem with PC video bioses. In the early
days the Linux/Alpha bootloader had a freeware x86 emulator to run
the vga bios code. This emulator wasn't fast enough to emulate a timing
loop inside of my ATI mach64 bios, so the clock chip didn't get the
right timing. The DEC people put in a lot of work in their x86 emulator
to bring up a mach64 card (and did it again to bring up matrox millenium
cards). I guess, that they are using a similair trick, as they do with
freeport (a sparc "emulator" for Alpha). Freeport translates the native
Sparc code to native Alpha code.
See, you not only have to be a good coder to create a system like Linux,
you have to be a sneaky bastard too ;-)
