I am trying to install debian on my wife's computer. It already has Windows XP installeld and running on its own partition and used to have Mandrake 10 on another Partition. Both WindowsXP and Madrake 10 recognized all hardware components including the built in network chipset.
I tried different debian CDs including Sarge testing net-install and Etch testing net-install and finally Sarge Stable DVD from Linux Format Magazine Cover CD. All these CDs have the same problem.. network is not work-ing :-)
I even tested the network chipset by using Knoppix Live 4.0 DVD and it was detected and automatically configure properly.
Here are some information I gathered so far, and all help is greatly appreciated:
