Title?



Since I use Google to find out pretty much everything, I thought I should have a page of things I had to work out for myself because 'the internet' didn't seem to know. Now it will.

Can't boot from a CD?

Short version: Make sure the IDE controller that the CD drive is attached to is actually enabled.

The BIOS on my ASUS motherboard allowed me to choose 'ATAPI CD Drive' as a boot device, and on boot, no matter what CD (or CD drive) I tried, the drive would make a few noises, but the system would not boot from it. It turns out that the ATAPI device I had selected was actually some sort of dummy device; the system wasn't even trying to boot from the CD I had put in, because the Marvell IDE/PATA controller the CD drive was connected through was not actually enabled. With the controller enabled (somewhere in BIOS), there was a new, 'real' CD drive to select as a boot device, which of course worked straight away.
