I didn't say anything about a password. I finally sorted it myself tho.
If I remember correctly this is how I done it.
I restored all bios to defaults, enabled the CMS mode and restarted I think then it went back into BIOS, so I did same again but then enabled the second option that is also part of CMS once that gets enabled saved it and it eventually came out of BIOS.
I can't say this is exactly what I did but was around these lines. It worked fine for me, I did have to reinstall Windows 8 after it due to hard drive being knackered.
This is a follow up question, not an answer. Got the same problem, only my bios wont accept enabling cms.. Tried all other possibilities. Updating the bios wont work either, cause it for some stupid reason needs 20% battery, and my battery is dead and gone. Any suggestions Will be very much appretiated!
