Hi!
I just got a new Abit BX6 motherboard, but it's missin the bios rom chip.
Does anybody know what the default chip id is?
Any 27c010 EEPROM would work (128kB), 28 pins that is.
i386 16 ⇒ i486 DX4 100 ⇒ Pentium MMX 200 ⇒ Athlon Orion 700 | TB 1000 ⇒ AthlonXP 1700+ ⇒ Opteron 165 ⇒ Dual Opteron 856
Thx for the answer, but it seems i don't have one...
Also the socket is 32-pin.
Would any of these work?
A290021T
W29C020C
SST29EE020
W49F002U
W29C011_EP
About any listed will work, as long as you enter this command while at a DOS prompt before flashing:
"copy /b bios.bin+bios.bin BX6_2M.bin" - where bios.bin is your original 128KB BIOS file.
The reason is simple - you have a 128KB BIOS, and you only have 256KB ROMs.
To flash a smaller BIOS on a bigger flash, just use the copy /b function, calculating how many times you'd need the BIOS image copied in order to fill the BIOS chip.
In your case, being a 256KB chip, you just have to copy it twice. For a 512K BIOS chip you'd have to copy the same file 4 times.

The w29C011 is a 1Mbit 5v eeprom so should work just fine. You would need to use a programmer like TL866.
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
So I discovered that the card is a BX6 2.0 because of the location of the ATX power-connector.
I used my T48 to flash the W29C011 with the QR bios.
But the motherboard was dead, my pci diagnostic card showed no life.
So dos the rev 2.0 use a different bios or what could be wrong, all other parts I use are tested ok.
Solved, used the SST29EE020 rom.
