Well, it would appear that I have solved the kernel CDROM blindness problem with my DFI P5BV3+ mobo. I reconfigured my hardware this evening, putting the CDROM drive on the primary controller as a slave and putting my Linux system on its hard drive as the master on the secondary controller. The BIOS still doesn't assign an IRQ to the secondary controller, but at least Linux recognizes the drive and can boot from it using a floppy. Morale of the story: - Don't bother with DFI motherboards, at least the P5BV3+, if you have more than one hard drive and a CDROM drive. - Attach your drives so that the CDROM drive is the slave on the primary controller. other drives should follow on the secondary controller. - Read Documentation/ide.txt if you have an ide question. - Don't give up. There is more than one way to skin a cat (and if you are skillful, it may look like a rabbit). BTW, my BIOS still does not assign the secondary controller an IRQ and it refuses to recognize my WDC Caviar 32500 drive on the secondary controller. (Fortunately, Linux is smarter than my BIOS. Chalk another one up for Open Source!) Cheers, Sean T.
