lpc hot swap and flash

[professor_jonny]

I have a motherboard that suffered a bad flash I desolderd the flash chip soldered on a socket read to do a hot swap flash.

so I booted up another motherboard with a lcp flash chip that had a 49lf020b chip and swapped the chip from the dead motherboard and poped it in and I get no flash config on the desoldered chip.

I then noted the flash chip is slightly different it is a 49lf002b not a 49lf020b

is there a way I can get this wrongly flashed chip to program in the working computer or would I need a motherboard with the same bios chip?.

hmm

SST  49lf002b

 49lf020b its also 2Mbit LPC Flash

So i think you should reset Flash on working mother board (Battery off...) and than read It using IC programmer. Hot swap is not working in every situation.
