The HOWTO disagrees with the kernel source.

Thanks for the information.

Whoops. I should have read the source better.
linux load=ide-generic hda=remap
This should give you "hda: unknown partition table". Does it do this? If
it does, then this makes me sure that the code just below the correct
line runs at all. If it doesn't, things are really strange.

This is a sign of a scratched CD. Some CDs read fine when read
sequentially (as CD copying programs do), but fail with random access.

linux clock=pit
One last preparation for tomorrow. I will send you an updated (i.e.,
with a kernel patch that adds some debugging printks) initramfs image
soon, and I want you to learn how to load the LiveCD kernel and the
initramfs from GRUB. This is very easy: just put them (i.e., "linux" and
"initramfs_data.cpio.gz" files) somewhere on your hard disk where GRUB
can find them. Add the kernel to GRUB without the root=... argument
(i.e., just "kernel /path/to/linux clock=pit load=ide-generic
hda=remap63"), and add initramfs_data.cpio.gz as the initrd. Then boot
to the GRUB screen, insert the LFS LiveCD into the CD-ROM drive, and
select this kernel in GRUB. It should behave exactly as if you have
booted from the CD. Once you complete this and notify me about this, I
will build the updated initramfs for you to try instead of the original one.
