I have an old IBM laptop A20m running a Celeron 500MHz with 512 MB RAM,
running Windows 98SE.

The laptop is a hand-me-down and it is not actually registered to me in any
way. I do have the original IBM disks.

I would like to upgrade to XP.

Here comes the dumb questions...

Do I purchase an upgrade, or a stand alone XP full version? And what about
which service pack#? And Home Edition or Pro?

Where is the best legitimate place for making the purchase? What should I
expect to have to pay?

Many thanks.

-Dennis
