Were you running 98 before? If so you need NT drivers for the integrated stuff. If HP can't provide them your only options are....
Disable them in BIOS and use add in cards.
Find out what those Solderins are and try to get NT drivers from the Mftg sites.
Go back to win 98. And there is a good chance the actual drivers are on one of those "recovery cd's" that come with OEM systems like yours
