Re: Bios flashing continued

[Yap Ee Huey]

Hi,

I have been looking for a program to flash my eeprom
as well. The standard flash programs do not allow me
to burn unidentified bios. I have found two very useful
and general flash and burn programs :

(1)UNIFLASH  (DOS program)
http://www.pppr.sk/rainbow/programs.html

(2)/dev/bios  (Linux program)
http://www.openbios.info/development/devbios.html

Hope it helps u ! Although they don't work on my board
-> TUSL2-C  (eeprom SST49LF002A)  because of some
undocumented write protect registers maybe.

good luck,
eehuey

Interesting... I don't have floppy access to the board so unfortunately 
this won't work either.

This program segfaults when I try to load the module for the board, 
though it works fine on some of my other machines.

The thing is I think devbios supports the chip I have, but that 
something weird is happening (obviously) that I don't know about. Most 
of the code I've seen assumes that the sis chip is coupled with a 
superio chip that mine isn't either the sis950 or the sis 5595 or 
something like that, when mine is a ITE8661 (to which I have the spec 
sheet, but don't know what they are trying to do with the other chips 
so don't know what to change to make it work for mine).

oh boy, that looks fun. Let's just try to get flash_rom working -- I don't 
have time to debug this one :-)

Can you make a DOS bootable ide disk on another machine, put uniflash
and the rom image on the disk and then boot from it on your target
board?

So far I found that uniflash is the only working thing (which means 'no
dancing around with a voodoo tambourine') out there. flash_rom never
worked for me, not even on the sis630 board for which it was originally
designed.
