What I would like is for Toorox to install and take the whole hard drive. I have an older Dell machine using SCSI drives. Toorox does see the drive and existing Linux partitions. It seems to go through the install with no errors. But when you reboot it is unable to find the kernel or apparently the boot partition.

Any suggestions would be appreciated.

Hi awalker1!

You are welcome. Sounds like a "not included kernel module" for your device.
From live - open a terminal and check:
dmesg | grep scsi

Sorry, i was a little bit fast! You do not see the penguin(s)?
Then it is a grub (bootmanager) problem. Any error message?
Have you installed grub into the MBR of your boot hard disk via the toorox-installer or modified an existing bootmanager?

Here is some further information.

I was able to get the Grub boot process started. I can now see the Penguins and it starts loading. But it stops giving a kernel error:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

When booted into the DVD I can mount and access the drive without any issue. This is an older LSI SCSI card and I think it is a module problem. Is there a way I can fix this?

Yes, it is a module problem. You have to find out which modules are needed
for your card.
From DVD:
dmesg | grep scsi
and the dependencies of the module:
lsmod | grep MODULE_NAME
Then you have to create a ramdisk with the scsi modules inside.
Here is a good ramdisk tutorial using initramfs:
http://en.gentoo-wiki.com/wiki/Initramfs
Copy the necessary modules from /lib/modules/2.6.28-gentoo-r2/kernel/drivers/scsi/... to the initramfs directory.
There is a line in the init script:
# do your magic here
There you have to insert:
insmod /PATH_TO/MODULE_NAME1
insmod /PATH_TO/MODULE_NAME2
insmod /PATH_TO/MODULE_NAME3
...
Copy the finished minirt.gz to /boot of your mounted Toorox partition and edit /mnt/toorox-partition/boot/grub/grub.conf:
Remove # in the initrd line.
Finish! Toorox should boot now.
