Sorry, you are both wrong. The USB cable is used _only_ for power. All data goes through the parallel port. It is a slow (5 minutes to burn and 2 minutes to verify), cheap burner, but I have found it to be extremely reliable.
I was talking about the Enhanced Willem Universal Programmer. Perhaps, the two of you were talking about another, possibly hypothetical flash programmer.
Just to verify once again, there is no known linux bios programmer?
What about programming the chips in socket from within Linux; yes risky, but this does work right? The reason I ask is because that means that we do know *HOW* to program them, we just don't have an external device to do it.
I guess this is just another project to start with a bunch of people that know how to program fpga's.
Thanks for everyone's feedback to me as a new person here.
Jeff BTW: you might be able to speed up the programming of the chip if you do it in burst mode. Lots of NOR flash chips support this. Are PC bios chips usually NOR or NAND or something else all together? The code I saw for the M-Systems chip in my machine looked like it was doing the classic NOR state machine triggers (write 0xAAA, 0x555, etc). So I'm guessing they are more like NOR than NAND. NAND would suck anyway because it's not very reliable. Using NAND would be insanely stupid! (IMHO)
