kernel accessing pata cd rom drive instead of sata OS hard drive for filesystem
 

We notice that for some reason, when booting up our computer with the Red Hat operating system located on a removable Sata drive,
we get a kernel panic message because the
system is trying to access the CD ROM drive (PATA master) instead of the OS (SATA Master) drive for
The /dev/root directory. The kernel starts to load before displaying the
following message:

Creating root device

Mounting root filesystem

Mount : could not find filesystem ‘/dev/root’

Setting up other filesystems

Setting up new root fs

Setuproot : moving /dev failed : no such file or directory

No fstab.sys, mounting internal defaults

Setuproot : error mounting /proc : no such file or directory

Setuproot : error mounting /sys : no such file or directory

Switching to new root and running init

Unmounting old /dev

Unmounting old /proc

Unmounting old /sys

Switchroot : mount failed : no such file or directory

Kernel panic – not syncing : attempted to kill init![/B]


The only way to get the system to boot is by disabling the
PATA interface in the BIOS. I tried hard coding the SATA OS
drive (root = /dev/sda2) in the GRUB file but that didn't have nay affect.
