I was given a Toshiba 5105-s501 laptop with a :"bad hard drive", so I
picked up a 40gig from one of my computer outlets this week and
installed it.

Its still not seeing that there is a harddrive in it. Booted an XP Cd
and it loads the software..then says it cant find a harddrive

No way to get into the bios on this machine that I can find.

Anyone have any ideas about how to set one of these machines up?

Try the OLD hard-drive on another machine. You can connect it to
desktop PC with adapter. If it works ok, then the drive controller
on the laptop has failed.

If the laptop works, you might need recovery disks for it
from Toshiba to setup the new harddisk..
