csm has screwed up systhem

[Novel8]

csm in bios was disabled in order to install win 10 via ssd drive. ....now i can't boot my system or get back to the bios, to undo csm back to enable. MB manual of MB ausus A88x-pro says to push Direct Key to go directly to Bios, but it doesnt work.

Seems on your Asus motherboard to access the Bios you use f2 + Delete keys instead of a single key.

Yes, i know about that link and about clicking Delete and/othose werdoesr the F2 buttons...but they only work when u can get into Bios. The MB says dircect key button on the MB itself would get u into Bios...and i tried that and it did not work.

Seems the simple answer turned out to be to remove the cmos battery and my Bios went straight to default.

May as well put a new one in there...average lifespan approx 5 yrs...
