Use a USB flash drive to install a snapshot

[Joe S]

Has anyone been able to configure a usb flash drive to boot a snapshot
install? I don't like to burn so many cd's. I tried to install via
PXE, but the laptop I use (Thinkpad X24) doesn't support PXE. I've
been able to install 4.3 from usb flash drive thanks to these
instructions: http://www.azbsd.org/~marco/openbsd/flashkeyinstaller/
