Need NIC driver for PowerEdge 1950 - for Vista Business 64 bit

[tankman1989]

I'm installing Vista Business 64 bit on a dell poweredge server that has 2 broadcom NIC's that aren't supported on the Vista DVD. I tried downloading the drivers from the service tag page on Dell's website but I can only find drivers for server 2003 and 2008, which won't work with Vista. I can't even figure out the chipset of the NIC, so any advice here is greatly appreciated!

I know that this computer will work with the Windows 7 install DVD so is it possible to get the driver from that?

I installed a secondary Intel NIC which was recognized and am getting the drivers via auto-search online...
