Maybe ebay.com item number 260876657637 can help you. Is your BIOS chip socketed or soldered to the board?
Hello It's soldered. Memory is in SO-8 package. Yes, that's it. Thank you very much. But i think i still can reprogramm my old chip and it'll work. Ihope that someone will send full copy of flash to me. I'll wait few days. If there'll be no response i'll buy it. Thank you very much again.
