RIS Boot disk

http://www.roudybob.net/?p=124

The Network Interface Card (NIC) that Virtual PC 2004 uses is not PXE compliant.  PXE is short for Pre-Boot Execution Environment.  PXE-enabled NICs allow a computer to boot from the network - just like they can boot from a CDROM or a floppy drive.  They access an image on a server over the network that allows them to boot up and run operating systems, software, diagnostics, etc.

And check the comments as well for another HOWTO!

Incidentally, check http://support.microsoft.com/?kbid=891372 if the bootdisk won’t find a DHCP server.

This is just nine colours of awesome, in that it also goes through RIS deployment into VPC
