First post, by squelch41
I have a V4P895P3/SMT V5.0 486 VLB board with a 28 pin AMIBIOS chip.
However, the bios ID string at POST seems to show quite an old bios version - a V4.0 board bios with ID AMIBIOS ID: 40-2004-428003-00101111-072594-OPTI802-H
The latest seems to be V5.2 with ID AMIBIOS ID: 40-2207-428003-00101111-072594-OPTI802-H
I can find what I think is the V5.2 file online and looks like is 64kb in size.
I've never programmed an EEPROM before - all previous PCs self flash 😉
Do I just need to get any 64kb dip 28 eeprom (eg https://cpc.farnell.com/atmel/at28c64b-15pu/e … 8c64/dp/SC09513) and a cheap programmer (that has enough pins) from ebay/aliexpress?
Can anyone recommend any cheap programmers that can do this?
Alternative I was thinking of was building one such as the TommyPROM design:
Are there any major pinfalls/hints/tips that people could share
