A MoBo with no MAC chip, therefore no LAN connection?

I just installed a Biostar 6100-939 motherboard. I am tryig to set up my internet connect (broadband cable modem via a NetGear router).

However, after a fresh install of XP-SP2, windows claims it can not find my network hardware. I started wondering if I was lacking a LAN driver.

A review of the motherboard's specs shows that it has a 10/100 LAN PHY chip from Realtek (RTL8201BL/CL).

However at the Realtek web site, regarding the RTL8201s it says:
The Ethernet hardware consists of two parts: a PHY chip, and a MAC chip. It's the MAC chip that requires the drivers. RTL8201x is a PHY only chip which does NOT need any driver at all. If you have RTL8201x in your computer system, there must be another MAC chip in the system too. Most likely, the MAC chip is embedded in the chipset. Please contact the board or computer provider to find out which MAC chip is in your system and how to get the drivers for it.

So how do I know what MAC chip I have, if I have one at all?

If this lack of a MAC chip (or a MAC chip driver) isn't the issue, any other thoughts as to why Windows "can't see my network hardware?"

Thanks

Install the drivers that came on a Biostar CD and/or download them from nVIDIA and install them. It's an nVIDIA nForce 410 / 6100 board. You'd want the platform driver set and the video driver from nVIDIA.

When installing the drivers, don't install the active armor / firewall stuff unless you want to risk difficulties.

Similarly it's not advisable to install the nVIDIA SW IDE drivers unless you need them for nVIDIA RAID.
