Hi all

My pc is based on mainboard PCChips M810LR, Chipset: SiS 730 rev 2, socket 462 Athlon 2200+

The bios is Amibios in in Plcc32 686 AMIBIOSĀ® Ā© 1999 AS23 1083 chip ATMEL AT49F002T_V3

I have a bios chip poorly written, I tried to update it but I had disabled the Usb ports, can not write
with utilities Aminfxxx

Perhaps bootblock does not allow the new writing on Plcc32

Recommended me the best utility for flashing the bios?

What kind of chips can replace PLCC32 Atmel AT49F002T_V3


Thanks in advance :D


Regards

The AT49F002T can be replaced by any other 256kB (2Mbit) 5V PLCC32 flash chip. just make sure to use Uniflash or Flashrom to program the chip. You can even hotswap it on another mainboard that supports 2Mbit chips.

they all should work. look for 2M or 256kx8 PLCC32 5V chips. and make sure to use uniflash or flashrom to flash them. that's all.
