Ah, so you wrote that :) Then you also know what board that write 
protect had to be disabled for there :) I gathered someplace that this 
was needed for some asus board, right?

My other KM400 based system (Asus A7V400-MX) refuses to have its ROM 
identified, while it uses the same well-supported VT8235/SST39SF020A 
combination as found on the EPIA Ms. This behaviour didn't get altered 
by that patch.

I tested various combinations for the io pins, yet didn't get anywhere, 
all i haven't tried yet is reboot the machine (in the off chance that 
that changes anything). Mind you, this testing was done more than a 
month ago, when i ordered the willem and wrote that patch, but i can 
freely access that machine at all times.

This motherboards BIOS is supposed to have a "CrashFree" BIOS, and i 
have a hard time finding out what that actually is supposed to do. I 
have a hard time looking through the marketing, and some bits have 
already fallen off the web.

Here's the marketing from Asus' site:
"CrashFree BIOS allows users to restore BIOS data from a floppy diskette 
even when BIOS code and data are corrupted during upgrade or invaded by 
virus. Unlike other competing vendors' products, ASUS motherboards now 
enable users to enjoy this protection feature without the need to pay 
for an extra ROM."

There have been several of these crashfree things in the course of a few 
years, all are more or less equally obscure.
