And here's something I found out recently...
On some of the newer machines out there at the moment (esp. Dell) there IS a key stroke command to force it to give you a boot device option (Floppy, HDD, Network, CD etc...) so you don't keep on having to go into the BIOS and change your boot order. F10 and F12 on boot up seem to be the norm on newer boards.
Just something that's made my life a little easier
