I am fighting the new HP DC5700 model PCs. When using the ZEN Boot CD,
the network card is not recognized. Does anyone have any suggestions on
how to create the ISO for the boot CD? Or does anyone have an already
made ISO with the network drivers for this model PC.

HP DC5700
NIC - Broadcom Netxtreme Gigabit Ethernet (B57XP32.SYS File Version in Windows)

Any help would be appreciated. I downloaded the new Linux drivers from
Broadcom but I have no way to compile them.
