I checked your file bios dump, unfortunately it's not correct, it contain FF symbols only. You need to read your bios dump from your bios chip again, may be multiple times and compare in any hex editor (for example HxD), all dumps should be identical.
If you will meet with some problems with read bios dump from your bios chip, then try to use different software version. Also check the reliability of the connection of the contacts between SOIC-8 clip and your bios chip. Also don't forget to install driver for CH341A programmer.
All software versions for Ch341A programmer I placed into this link: https://files.fm/u/n9axkht6q
I recommend you use software AsProgrammer_1.4.1
