Cannot boot from CDROM after change to AHCI

[Hairy_Scot]

I recently switched from IDE to AHCI in the BIOS of my Gigabyte 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.

Go into your bios and change the boot priority setting and set the cd rom/DVD as the first drive, save and exit and try again.

Already done that.

Sytem either ignores CD or just hangs

No guarantees, but I've seen this on Gigabyte's before. The problem is often how the first 4 SATA ports are used.

HDD/SSD use SATA2_0~SATA2_3
ODD(DVD) use SATA2_4 ; the SATA port parallel to to the ground.

/edit - then just to make sure the correct drivers are loading run 'Fix It' - http://support.microsoft.com/kb/922976 and reboot.

Found out from Gigabyte forum that Ports 4/5 can be set to IDE.
Did that, and all OK now.

Apparently my DVDROM is a bit too old for AHCI.

Thanks to all who responded.


Is there a way to flag this thread as solved?
