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?
