Network Boot Floppy for Laptop

I have been successful in creating network boot disk for desktops, however, I would also like to do this for my Dell Latitude CPt and CPiA laptops. They have 3Com 10/100 network PC Card Adapters, and also Xircom Realport PC Card Adapters

Stepwiseinstructions, and or copies of your own boot disks would be much appreciated.

TIA
Charl
