Cannot boot from CDROM after change to AHCI

[HairyScot]

I recently switched from IDE to AHCI in the BIOS of my GA-MA785GMT-UD2H and now the system just ignores the Boot from CDROM Option.
Everything else is fine: boots to Windows OK and Windows runs OK.

Hi there,

believe it or not this is fairly common and is usually down to the DVD/CD drive's firmware rather than the motherboard. I have experienced this myself on several different boards and the only solutions usually are:

In BIOS set the OnChip SATA Ports 4/5 type to IDE and connect your drive to one of these ports.
Check to see if there is a newer Firmware version for your DVD/CD drive.
Get a newer model DVD/CD drive.

Hi

Yes, what absic said is perfectly correct and is something we see quite often. SATA optical drives are very cheap now and you can pick up a good one for under £12.

That fixed it!

Thanks a mil.

Updated MB Bios to latest level.

Can now boot from DVDRAM without need to set SATA 4/5 to IDE.

I can't boot  from CDROM Option (LG GSA H66N sata) in my GA-970A-UD3, rev 1.1, Bios F6.
HDD boot ok in windows 7 64bits.
I don't know if usb can boot, i haven't tried  yet.

¿Is the problem the DVD firmware ?

Thank's.
