I have a Dell Precision 360, which has both onboard SATA and ultra ATA controllers, and I put one of each kind of drive into the bays to make an experimental machine with the xen kernel.
After enabling both of drives, the BIOS recognizes each drive, but it fails to boot, giving me the message "secondary drive 1 not found". The BIOS gives me a choice of going ahead or going to setup. Choosing 'continue anyway' has no effect.
I can circumvent this going to F12 to manually choose to boot from the 'Primary Master' (rather than the SATA primary, or the CD, or Hard Disk Drive C:). I still get the warning about secondary drive 1 not found, but now I can choose to go ahead. At this point, grub takes over and everything is fine, boots fine, both drives show up.
In fact, I installed CentOS from the DVD, and during installation there was no hint of a problem with using the two drives.
In the BIOS setup, I do not get all the drives to choose from -- just Hard Disk Drive C: and the CD.
Can anyone suggest a way around this?
