Hello Everyone,
What I thought would be simple turning out to be a bit tricky.
I purchased a 200G hard drive and an Ultra ATA PCI card (IDE) controller card. I
did this for performance and later scalability. The problem I'm having is that
the new ide device wasn't being recognized(looked at /proc/ide, /var/log/dmesg,
etc). It seems that the problem can be rectified by passing the parameters to
the kernel in grub. I found this site:
http://www.captain.at/programming/ultra-ata/
"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
[...]
02:0b.0 Unknown mass storage controller: Integrated Technology Express, Inc.
IT/ITE8212 Dual channel ATA RAID controller (PCI version seems to be IT8212,
embedded seems (rev 11)
Subsystem: Integrated Technology Express, Inc.: Unknown device 0001
Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 11
I/O ports at a800
I/O ports at ac00 [size=4]
I/O ports at b000 [size=8]
I/O ports at b400 [size=4]
I/O ports at b800 [size=16]
Capabilities: [80] Power Management version 2
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. "
So I do the lspci -v:
02:09.0 Unknown mass storage controller: Integrated Technology Express, Inc.
IT/ITE8212 Dual channel ATA RAID controller (PCI version seems to be IT8212,
embedded seems (rev 11)

I/O ports at 2800 [size=16]
Expansion ROM at <unassigned> [disabled] [size=128K]

Although it seems that my ports are reversed I do the same thing (but found one
other bit on another site I added:
title Red Hat Enterprise Linux ES (2.4.21-20.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-20.EL ro root=LABEL=/ ide2=0x2820,0x2816
ide2=autotune
initrd /initrd-2.4.21-20.EL.img
When I reboot I can see that /dev/hde is found; however when the processes are
starting I get a kernel panic. I currently don't have a server set up to capture
the kernel panic dump but I did write down the code if it does any good:
8b 87 c4 00 00 00 85 c0 74 0c 8b 00 8b 5c 24 30 83 f8 ff 0f
I've tried variations of the B number (eg raising it lowering it) and I either
get a kernel panic or it hangs after it reports attaching the ide-driver (I
think to hde).
Does anyone have any idea.
Thanks,
James
