presiao 700z trouble

OK, bear with me, because I am very,very bad with laptops, not to mention I cant get around to well on a desk top.
Fixing (cough) a compaq presiao 700z which is all boggered up from to many kids. Fixed a desktop from the same family, which had 2 viruses,4trojans, and over 900 items of spyware and malware, not to mention enough APPs starting at boot to run a small country. So you can see what I am up against.
1st, when I get into the BIOS (Phoenix), it only has 3 tabs, Main-Boot-Exit. No advanced or Power,,, no PCI Configuration etc... Is that normal on a laptop?
There is 2 NIC's. a onboard and a 802 docked to the side. I want to use the onboard so I can run a ethernet cable directly to it, not use the wifi. But I am not getting a connection. And I thought maybe since it was onboard, it may be disabled in the BIOS. In device manager it shows OK. Nor, do I see any other obvious problems with it.
Anything to help me get this online would be greatly appreciated.
Thanks

peace be with you
