I have RHEL4 in my computer. I need help installing Airlink101 PCI WLAN card.

card Details:

Airlink101 card is AWLH4030 and it Atheros Super G 108 Mbps.

OS Details:

Version: 2.6.9-34.EL
Single Processor
Arch: i686
RHEL WS 4 (Nahant update 3)

I am real new to linux, so a bit detailed on how to install by steps would be of great help and a reference like that is equally good.

Thankx in advance.
