Tosh:
Actually, I figured out how to do it:
1. Using fdisk, I created two partitions on the drive:
/dev/sdc1 = 15 MB
/dev/sdc2 = The rest
I marked the first one bootable
2. I used dd to copy the diskboot.img to /dev/sdc1
3. Formatted /dev/sdc2 as ext3 and copied the
iso images there
4. When I boot from the usb drive, I selected hard
drive install and pointed the installer to
/dev/scd2
It worked perfectly!
Thanks,
Neil
