AHMED, my previous post is direct reply to Richard. 
Backup BIOS will always different than original one. I did a comparison while ago between original BIOS & backup BIOS. I found there will be slight different between the two. However, I'm no longer have the files to show you here.
If I recalled correctly, Richard didn't backup the BIOS on his computer but downloaded it from here (first post). If we follow the chronology carefully, that post is older than the samozen's post. In samozen's post, he mentioned the first hippotek's backup BIOS R2090J8 bricked his notebook. In samozen's post also, he mentioned hippotek have gave him working backup BIOS R2090J8. And samozen already tested it & it works.
There is only one version of BIOS R2090J8. There is no other R2090J8. However, all necessary precaution should be exercise. Please ask Richard to backup the BIOS again.
