sound card/network card

[abe flonet com]

I had Redhat 8.0 on my system. Recently I bought a new motherboard(ASUS 
P4PE)/processor which had a Broadcom BCM5702 gigabit ethernet and a ADI 
AD1980 soundcard built on the board.  When i booted the machine up it 
recognized the new hardware however after i booted neither the sound or 
network work.  For the network card, i tried to install the drivers off the 
cd.  After following the instructions, i got to the point to ismod <driver> 
and that returned "no such device found" (same with modprobe: 
driver).  That part did try to probe with the correct driver, but it wasn't 
working right.  For the sound card, I tried to run sndconfig which found 
the card but was unable to install the drivers for it.  Has anyone had any 
experiece with this board?

Thanks
Abe
