hi there,
I just got a new dell 580s with windows 7 and I3-530 processor. I 
partitioned the drive within windows and proceeded to install debian 
using the latest x86 net disk (I burnt the latest 150M ISO to a CD for 
the installation). Everythng goes fine except that it fails to detect 
the ethernet adapter. I'm then prompted to pick a driver from a long list.
I called Dell to ask which adapter I had inside and they said it was the 
Broadcom 57788. I couldn't find this exact model number on broadcom's 
website but from their website I learnt that they have a bunch of 
drivers like tg3, bnx2 and b44. I tried all three but none works.

I proceed with the install without network thinking it may work 
afterwords and was able to log in as root, etc. However, without the 
network support I can't do much.
Any help will be appreciated.
