Updated bios to 2.03, optical drive doesn't write to disks

2015-03-08, 21:56 PM

after an update to 2.01 then  2.03 the drive will not write to disks. software will claim to have written to the disks but nothing is on them. 

i found an earlier version of the bios (1.xx) which worked fine. I know going back to 1.xx will work but don't have that file. any assistance would be appreciated.

 

regards

No, restoring won't work. 

I had updated to 2.03 when it come out and found that it didn't write.

 

After a internet search i did find a bios version 1.x  wihich had me writing again.

 

I accidentally updated it to 2.03 again recently and alas i didn't save the old bios file.
