[SLL] booting a new kernel - unable to mount root fs

[Mathew D. Watson]

I have been trying to boot the new kernel I built last week, but I have 
not yet succeeded. After studying the GRUB manual (and many failed boot 
attempts), I have finally gotten my menu.lst file to the point where I 
can't find anything wrong with it.

The new kernel is /boot/vmlinuz-test.

The last several lines of /boot/grub/menu.lst are as follows.

### END DEBIAN AUTOMAGIC KERNELS LIST
title		linux-test
root		(hd0,0)
uuid		7882317c-a329-41cb-b59d-f7a7d0212c0c
kernel		/boot/vmlinuz-test root=UUID=7882317c-a329-41cb-b59d-f7a7d0212c0c ro

I have tried this without the root (hd0,0) line.
I have also tried using root=/dev/sda1 as a kernel argument.

The error message is:
unable to mount root fs on unknown-block(0,0)

Other messages complain about a bad root=.

I googled on the error message and found a posting that said:
you must run "make-kpkg kernel_image" comand with --initrd option.
Or just disable this initial RAM support in menu.

Unfortunately, I nuked my kernel source and build while messing with 
GRUB, so I can't run the make-kpkg command without starting over.

Is there a way to boot my kernel as it is without running make-kpkg or 
without disabling ram support in the menu?

How do I disable ram support in the GRUB menu? I think I need to press 
"e" and then provide a kernel option somehow.

Where can I read about the options passed to the kernel?

For reference:
The following entry from /boot/menu.lst boots the stock kernel.
