Be sure you use the link for product compatibility to verify before you use each.  I looked at a couple

and they appeared to be ok but I didn't look at all of them.  Remember that you need to load Notebook System Software

 and the Chipset Installation Utility in that order.  Suggested order for the remainder is Video,

 Network, Sound, and Modem (if you have one).  Any others in the order you choose.

 

I just took a closer look and found that the list doesn't include the chipset or the NSS.  You should be able to

find one for the chipset on the Intel site if one exists for Win 2K.  You may need to forget about

NSS, or you could try the one for Win XP as drivers for that os are similar to those for Win 2K.
