Thanks everyone! Lots of useful snippets.
Sounds like if my BIOS co-operates then it shouldnt be too difficult. Just got to make a boot disc on cd then, must admit I'd never thought of using USB for booting though.

If I hadnt just bought a new card reader then using the released flap for that would have appealed.
Any more brain waves greatfully accepted
