Ultra ATA - 133 PCI Controller (ITE - Integrated Technology Express, Inc.) on Fedora Core 2
I was installing an additional IDE controller card into my machine, so that I have 2 NTFS harddisk's
on the motherboard's IDE controller (master/slave - primary/secondary) and an addtional disk
with Fedora Core 2 on the new ATA controller.
My BIOS detected the new card as SCSI device and I was able to boot from the HD, but it resulted in
a kernel panic:
mkrootdev: label / not found
mount: error 2 mounting ext3
pivotroot: pivot_root(/sysroot,/sysroot/initrd) failed: 2
umount /initrd/proc failed: 2
Freeing unused kernel memory: 148k freed
Kernel panic: No init found. Try passing init= option to kernel
The solution is to pass additional parameters to the kernel in GRUB:
title Fedora Core (2.6.5-1.356)
root (hd0,0)
kernel /vmlinuz-2.6.5-1.356 ro root=LABEL=/ rhgb quiet selinux=0 ide2=0xa800,0xac02
initrd /initrd-2.6.5-1.356.img
Here is how I figured out the correct values for ide2 (and ide3). I booted with the Fedora harddisk as
slave disk on the motherboard controller and issued the lspci command:
# lspci -v

You see the lines starting with "I/O ports". Construct the kernel parameters with the following formula:
ide2=A,B+2
where A is the address of the first I/O port and B the address of the second I/O port plus 2.
