SOLVED;GRUB woes

I decided to reinstall Arch 0.8, from scratch, just for the sake of doing it. (Keep sharp. )
I have 3 sata drives. When I originally installed Arch, I only had 2 drives.

1- Seagate 80GB recognized as sdb
2- Seagate 160GB recognized as sda w/Windows vista
3- WD 250GB recognized as sdc w/Windows XP

Now I installed Arch to sdb1, grub to sdb and swap to sdb5.

Seagate 80gb is set to first boot device.

I am at work, so I don't have my grub with me, but I recall the root being (hd1,0).
The vmlinuz is directed to sdb1.

When using this configuration (setup by the Arch installer) I get an "unknown files system type" error. The drive names have shifted or something! It is being directed to one of the NTFS drives, apparently!
Now, when I hit "e" to edit the grub arguments, I changed it to root (hd0,0) and sda1, and I get a bit further; it starts to boot, but then I get a kernel panic error, not syncing, after a few moments!
What am I doing wrong, if someone can tell from the information above? Do I need to edit fstab, perhaps?

PS. Many moons ago I ghosted drive 1 (Windows XP) to drive 3, formatted drive 1 and used it for Arch...don't know if that matters.

Typical SATA controller confusion. Check out UUID or other persistent block device IDs. There is a wiki page somewhere in the Arch wiki that explains how to.

Ok, I'd like to use /dev/disk/by-label.

My kernel line will look like this:
kernel /boot/vmlinuz26 root=/dev/disk/by-label/root vga=773

but what about the root(hdx,x) line?
Won't I end up in the same boat with random names haunting me if I keep it as root(hd1,0) ?

Well thanks so much for the tip. /dev/disk/by-label works beautifully in grub and fstab.
I suppose since I have 2 SATA controllers, they were fighting it out for supremacy or something, because during the installation the drive I installed Arch on was recognized as sdb, but after rebooting, it changes.....weird....

Even if you've already solved the problem, this might come in handy for somebody;
