Hello ollie!
As far as I understand, it's you, Ollie, who wrote that flash_rom program? My SiS630e board (pcchips m787cl+) has an EON EN29F002NT flash part on it and I also have a spare old 1Mbit SST29EE010 part. I saw the program supports SST29EE020... I thought (just an assumption) that SST29EE010 may be similar to SST29EE020 in all but the size, so I patched your program a little (added a record to the flashchips array and also added some #define's to flash.h) so it agreed to flash my spare chip. Unfortunately it didn't work. The flash_rom pretends to work, but quits after "Verifying 0x00000001". The board doesn't boot and when I place the EON part back in place, the board's CMOS turns out to be ruined.
I doubt it will work. Every EEPROM parts have slightly different command set/cycle for programming. You can not just change the ID and expect it to work.
Can you imlement a correct support for SST29EE010 please? It has a sufficient size to put a linuxbios in there, so I'd like to use that part if possible. I hope it is electrically compatible with the SST29EE020 and EON EN29F002NT?
I am sorry that I can't do it for the moment. Programming EEPROM needs a little bit of trial and error. You can try download the datasheet from SST and modify the 29EE020 code.
