A little more info to help others.
I looked for but could not find the broadcom .inf file in the windows partition. I did not want to search through the "12" recovery disks to find it. (why does it take 12 CD's to hold a Windows OS?) (I think half of the disks contain proprietary software from Compaq).
So I found the driver for my wireless card with a Google search, downloaded and saved it.
I then installed wine, then opened the .exe file with wine. I could then see the .inf file.
I then opened Network & Internet Configuration and configured the Wifi, choose "Use a Windows driver (with ndiswrapper)", choose "Install a new driver", search where you have the .inf file, click open. After the driver installs finish the Wifi configuration.
Hope this is useful.
