Thanks a lot to all who replied.
The OS on the USB stick is Minix3 - not a Linux.
So, it is not clear what I need to copy from the Minix
to the boot directory of my Fed 7.
I guess I need to ask this question of the Minix users list
to see if anyone of them has booted Minix3 via Grub.
Thanx,
JD

Hi
I haven't actually done this ... only something similar !!!!
1. Make sure your USB stick partitions are labelled uniquely, just makes
life easier. (/etc/fstab on the stick must match) /root_stick say for
root partition
2. Copy the kernel and initrd from you stick to your F7 /boot directory
- obviously check the stick file names are unique. vmlinuz_stick,
initrd_stick say.
3. The "F7" grub entry for the stick can then look something like
root (hdx,y) The same as your F7 entry
kernel /boot/vmlinuz_stick ro root=LABEL=/root_stick
initrd /boot/initrd_stick
Alternatives ...
Using F8 I have managed to boot an external "BIOS invisible" USB stick
1 grub on a CD
2 syslinux on a second USB stick
