In all honesty, Bart PE is a stripped down/modified version
of the Windows Pre-Instatalltion Environment (PE) that MS
provides to OEMs. The PE disks have a lot of drivers that can
be removed if the hardware support (things like hard drive
RAID controllers, misc sound and video cards, etc) is not
needed.

out the gateway, to the ISP...nothin' but net!
