Ok. I checked your files bios dump, unfortunately it's not correct. 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.

All software versions for Ch341A programmer I placed into this link:  https://files.fm/u/nkp4ztcb2

I recommend you use software AsProgrammer_1.4.1

Hello

I tried with AsProgrammer. I got identical files in the first time. I have attached both the file in the link https://files.fm/u/m6araznga Also, if you have any tutorial link for AsProgrammer to write modified bios or I can write it with ch341A programmer? Hope u can help. Thanks
