[oclug] Lexar Secure problem

[M&D Hickson]

Ok, I got FlashLinux onto the JumpDrive -no problem...almost. I had to
make an entry in my initial (Mandrake) GRUB file as this machine won't
boot from USB and rebooted. The Jumpdrive brings up the FlashLinux
splash screen and begins to boot but stops part way through with:

block device /dev/scsi//host0/bus0/target0/lun0/part1 is not a valid
root device
the root block device is unspecified or not detected
please specify a device to boot, or "shell" for a shell
boot()::

I made the changes LinuxFormat said were required ie:
change every instance of 'real_root=/dev/sda1' to
'real_root=/dev/scsi//host0/bus0/target0/lun0/part1'

and added the entries from the USB grub.conf file to my main (mandrake)
grub file changing hd0 to hd2 (they suggest hd1 but assume that you only
have one hard-drive). I made the same changes (changing hd0 to hd2) to
the USB grub.conf file after the first failure to complete booting.

The following is typical section of what I now have in my USB grub.conf
file and my main Mandrake grub file:

title=Encryptec Linux [1024x768]
root (hd2,0)
kernel (hd2,0)/boot/kernel-2.6.7-gentoo-r14 root=/dev/ram0 init=/linuxrc
splash=silent vga=0x317 screen=1024x768
real_root=/dev/scsi//host0/bus0/target0/lun0/part1
initrd (hd2,0)/boot/initrd-2.6.7-gentoo-r14

I assume somewhere in this process is where I've made an error. I'm
hoping someone (Jean-Francois Messier ? :-) ) can kick me back onto the
right path. Perhaps you could give me some indication of what you have
in your USB grub.conf file?

thanks
