Michael,
I've had to deal with a similar problem - the kernel detecting ide
drives on the wrong interface or not detecting the drive at all. This
problem turned out to be my machines non-standard hardware. The ide
autodetect code assumes the ide interfaces to be present at certain I/O
addresses, and using certain IRQ's. If (as was the case with my machine)
your machine uses different IO addresses or IRQ's, the autodetection will
fail.
In my case, my cdrom drive is actually on /dev/hde, but when I had
only two hard disks, the kernel autodetected it at /dev/hdc . I wasnt even
aware of this being an error, since my cdrom drive worked fine. When I
added a third hard disk however, it quit being detected at all. Eventually
I figured out that I needed to pass in boot params to the kernel for the
ide interface.
What params? Read /usr/src/linux/Documentation/ide.txt
Regards,
Kenneth
