If your notebook support USB, it should boot from USB drive. Look at this article: http://www.gentoo.org/doc/en/liveusb.xml

I have found info on the web about booting onto a flash.  However, all
appears spurious at best.  I want to put gentoo and ubuntu on a flash
(not at same time).  Will my t42 boot off usb?   If so can anyone
outline howto?
Thanks.
