I can not find the link right now, but there are boot disks and CDs
that will let you but from a USB device on systems that do not
support it. I ran across it on one of the live-USB sites.

It would be really useful to have the link...

Mike,
maybe my experience with booting from an external usb disk will help.
I also wasn't
"able to boot off usb devices since the BIOS is not arranged to do so"
[either that or I am too dense to properly fiddle with the BIOS].

So, what I did was copy the vmlinuz, initrd.img somewhere
onto  my internal HDisks, specifically in my case on /dev/sdb1.
Here is my grub.conf stanza for f10 booting off of the 2nd partition
of my usbdisk, [label rootusb2]

#24...68 ->  29..78
title Fedora (2.6.27.29-170.2.78.fc10.i686)usb2new TEST bootf10usb2 vga=795
root (hd1,0) #sdb1
kernel /bootf10usb2/vmlinuz-2.6.27.29-170.2.78.fc10.i686 ro
root=UUID=8f24a787-132c-4dc8-9126-9d85292e349f quiet vga=795
initrd /bootf10usb2/initrd-2.6.27.29-170.2.78.fc10.i686.img


I also did this recently with an f11 hdinstall into usb3.

Detail:
my usb disk is seen as sdc when booted up into my my main f10 on sda1
but when this bootf10usb2 boots it is seen as sda2, i.e,
disk order is reordered tousb=sda, hd1=sdb, hd2=sdc.

from blkid run from my mainf10on sda1:
/dev/sdc2: LABEL="rootusb2"
UUID="8f24a787-132c-4dc8-9126-9d85292e349f" TYPE="ext3"


However, this does not affect the "root (hd1,0)" for sdb1
ie that retains nonreorderd syntax,
even though when booted up f10usb2 sees sdb1 as sdc1.

This solution is not perfect of course.
I can't just take this external usb as is
to another computer and have this f10usb2 boot up
because the kernel, initrd can't be found.

HTH
Jack

Google "grub usb boot" and you'll probably be lucky.

I've not tried it yet, but someone told me to look at 
http://wiki.sugarlabs.org/go/Soas#Boot - it looks as though their boothelper 
link will be what you need.
