juvens Posted April 19, 2015 Share Posted April 19, 2015 I am using AW 17 (R5).And, using bios A14. But, I want to downgrade A09 version.In this case, can I flash A09 directly? or flash step by step like A14- 13-12-11-10-09? Quote Link to comment Share on other sites More sharing options...
Trabant Dave Posted April 20, 2015 Share Posted April 20, 2015 I don't think that there is any benefit in a sequential 'downgrade' as the whole BIOS is erased and rewritten; in fact the chances of anything bad happening would multiply by a factor of YxZ (where Y is the chances of badness and Z the number of times you rewrite the BIOS!) OK, the chances of a bad write are small, providing you follow the instructions to the letter; maybe you should revert the A14 bios to default - and write down the settings if you have a poor memory like me!And be sure to have the UEFI thing and RAID/AHCI settings correct or you could end up not being able to boot.......Hope this helps - maybe someone with more experience than me could give you more explicit instructions....RegardsDave Quote Link to comment Share on other sites More sharing options...
