I am trying to set up grub to boot from /dev/sda1

After copying LFS from /dev/hda4 to /dev/sda1 I realized I need to compile
SCSI support into the kernel. After successfully (no errors) doing that, I
wanted to set up grub to allow me to boot from /dev/hda1 (Mepis), /dev/hda4
(first LFS build) or /dev/sda1 (copy of 1st LFS build).

I chrooted into the environment before compiling the kernel
compiled the new kernel on /dev/sda1
followed all the steps in LFS 6.0 (make menuconfig, make, make
modules_install) then moved on to the grub setup. After typing grub I did
the following at the grub> prompt:
root (sda0,0)

and the system returned:

Error 23: Error while parsing number. My questions are:

1) Is there a place that I can find out what this error code (and others)
mean so I can try to figure things out before asking everyone?

2) Is there something special about SCSI hard drives I should know in order
to boot from them? (I did compile everything into the kernel that mentioned
SCSI)

3) How do I fix this?

Thanks

I believe it would just be
root (sd0,0) since 0 is a in grub talk.

grub does not speak 'sd0, sd1', etc.

Instead it sees hard drives as hd0, hd1, etc.

In my case, my SCSI hard drive is hd1 because my machine has 1 IDE drive (primary) and 1 SCSI drive (secondary).

If the SCSI drive was the only drive, grub would treat it as hd0.

Just thought anyone who boots from a SCSI would like to know.
