flash bios dos usb stick

[Trent Shipley]

I am trying to build a bootable DOS memory stick so that I can flash my BIOS.

The instructions (http://en.gentoo-wiki.com/wiki/FreeDOS_Flash_Drive) say:

And finally, you can install GRUB :
grub 
grub> device (hd5) /dev/sdb 
grub> root (hd5,0) 
grub> setup (hd5) 
grub> quit
--------------------------
The line:  grub> device (hd5) /dev/sdb 
is giving me trouble.

I know that the stick is mounted at /dev/sdd  but I don't know how to find the 
value that goes in the (hd5) part of the command.

http://www.freesoftwaremagazine.com/articles/grub_intro/
suggests 

# grub
grub> find /boot/grub/stage1
 (hd0,1)
 (hd2,0)

followed by

grub> find (hd2,0)/boot/im<TAB>
grub> find (hd2,0)/boot/images/

but this has been decidedly unsuccessful.
