Booting A22e from pendrive

[flashback]

First Thank you for setting up such a helpful support forum .

My A22e doesn't have a floppy drive and i need to have a more flexible\reliable way to boot other than from CD which i think its dying.
i don't know if i misunderstood what the bios indicated that when the floppy drive is disabled and USB support is enabled it says in the right pan that this will allow booting from usb FDD -b]or any other removable media [/b]
i used this tool (http://www.nu2.nu/mkbt ) to make the flashdrive bootable and i know by testing on other machines that it works.

my question is:
has any A22e user was able to boot from a flash drive?

another related question if you don't mind guys.........
if i was able to boot from a flashdrive can this method (http://forum.thinkpads.com/viewtopic.php?t=1363 ) work for A22e too ?

Thanks.
