I'm looking for the best tutorial for grub

All the tutorials I read for Grub didn't have anything to say about using SATA and IDE drives (i.e. Grub 0.97). From what I understand, Grub has crazy way of support for IDE drives. I had to use the SuperGrub CD to find out what Grub saw my IDE drives as, as well as my SATA drives. It seems there are no tutorials to explain this if you are muli-booting. Any suggestions?

Here is a great grub tutorial:

AFAIK it should not matter to grub if your hard drive is IDE or SATA. Perhaps your /etc/fstab is not set up correctly, or perhaps your IDE controller is not supported by your distro.
EDIT: If you have mixed IDE and SATA drives in your system, grub will often install to the MBR of the IDE drive by default.
See this from Herman's grub site:

If I am not mistaken, GRUB gets information from the BIOS on what the drives and partitions are. GRUB itself makes no distinction between PATA, SATA, SCSI, etc.

To see GRUB's version of reality, open the GRUB shell (enter "grub" at a root prompt), and type "geometry (hd0)" -----or hd1, hd2, etc.
