Could you explain that a bit further?
My understanding was that the f12 I see after I choose winpe at the Altiris blue screen PXE boot menu, is from the winpe image?
The only reason I believe that is because neither DOS and *nix ask you to hit f12 for network boot.
Wouldn't disabling PXE boot in the BIOS of the machine mean that it then cannot boot from the NIC card?
Thanks
