I am trying to utilize some old pc's using pilot linux (knoppix customizations) but most of the pc's bios do not support booting from cd.
what I am wondering is:
can I use a pxe capable nic to find the pilot.iso or the iso unpacked on the network on a server directory and boot from that?
(using Tftpon the server)
I'm also looking at a usb hub (usb over IP) that can plug into the network that I might plug a usb stick into that may allow booting from that :

dunno if this will work or not...
any ideas?

Has anyone used PXES Universal Linux Thin ?
http://pxes.sourceforge.net/
does it save as .img? .iso?
