the bios is incomplete ... it must have 8MB ... read the bios chip several times, use the HxD program and compare the copies..and if you have two similar copies, post here ..

Try NeoProgrammer and ASProgrammer software.You can make a backup with each one and then compare the files with a hex editor to make sure both are the same.Or make 2 backups using the same software and compare both.If they are the same post your backup.
i have my bios picture on my zip file can you guide me the proper setting to read that chip
thank you for help
the 8MB bios seems ok ... look in the programmer's software, what is written on the bios chip and select ... if you can't find it, try to enter it manually ... use this program..https://www.badcaps.net/forum/showpo...unt=10...other users have succeeded with it ...
