Well really almost any JDEC part 2MBits and larger will work. If you use a larger part you might have to ground the unused address lines if they left them floating on the pcb.
Thanks for the links. No luck with any of the links given, however. How to find a replacement part?
They are there but you just don't know what to look for. *grin* First off you part number is incorrect it should be W29C020 not W290C020. But there are't that many people who sell windbond. But you don need a windbond any 2MBit part will work as long as the footprint is the same... any 29?020 part will work.
Oh wait a minute... I bet you don't have a programmer do you? Ick. In that case foget what I said. You will need a part supported by the hot swap trick.
Ron. What flash parts are supported by your hotswap trick?
I did find out the extra zero in my search, thank you. Now I got a few hits at digikey. No, I don't have a FLASH programmer, but i can purchase one if needed, and the price is not to high. According what you write it does not seem to be possible to program an empy BIOS with a boot floppy similar to re-programming an existing one. Can I copy the content of the old BIOS with a programmer and start from there? How to proceed?
