Dell Latitude CPi a400xt hard drive upgrade from a 6 GB to a 80 GB not reconized it bios.?

I am upgrading a older 1999 Dell Latitude CPi model A400XT. Specs are: 400 MHz Intel Processor, 64 MB ram running XP Pro. (Service Tag VR4HH) with a 6 GB IDE hard Drive and I bought a 80 WD IDE hard drive. It is not being recognized in bios, in fact after I put in the new hard drive nothing is resettable. I have a few questions: 1. Is the 80 GB to big. 2. Can and how (at what site exactly) can I upgrade the bios? Would that fix it? 3. If I made the 80 GB an external would it be recognized?
I bought the Hard Drive on Craigslist so it is not returnable.
This is my Sister in Laws laptop and I am upgrading it for her.
Thanks for any help you can offer.

It probably just can't handle that size of a hard drive. I mean, you're laptop is over a decade old.
