I'm forwarding this message to the mailing list since the devs need to
know about bootdisk failures.

Can you boot other cd's using this drive?  The earlier livecd had a
problem where the kernel was missing the driver for my scsi card, but in
that case the system did start booting the kernel, it just failed when
the kernel needed to mount /.  Failing to boot off of the cd at all
suggests that either the bios isn't set properly, or your burned cd
might be corrupt.

No, that wouldn't be the best idea.  Can you boot from Tomsrtbt?  If so,
then after booting into tomsrtbt you can set up the filesystem (creating
and turning on swap space as one of your first steps), mount the cd,
extract the stage1 tarball onto a ready partition, use ifconfig or dhcp
to set up networking, chroot, and you'll be off and running.

Toms has the appropriate scsi support already compiled in (most likely),
so you don't need an initrd.  In fact, you don't want to build a
bootdisk from the image; you just need enough to get you going.

Hope that helps,
