Say Y here if you intend to run this kernel on the Compaq
Personal Server.
Saying N will reduce the size of the Footbridge kernel.
The Compaq Personal Server is not available for purchase.
There are no product plans beyond the current research
prototypes at this time. Information is available at:

Server, send e-mail to <skiff@crl.dec.com>.
