HI,
The last version of redhat I tried was 9.0. I have tried 8.0 and 9.0 and earlier versions. I also tried mandrake 8.2 and 9.0. Nothing so far has kept me shut up as SuSE, LOL (which is a good sign) (y)
Since you have the Nvidia port on Auto I see one of two possible scnearios
1.) Somehow, your system is disabling the Nvidia "automatically" because you have another port
OR
2.) Linux does nto like the driver (if any is installed) for you Nvidia Lan port.
You would have to investigate deeper to find out if the LAN port ios turned off. Does hte LAN port pick up in windows? If so It definately means either Linux does nt have a driver for it, or linux does not recognize it.
I took a breif look at your system specs. Even though Linux is not yet 100% on top of hardware issues as Windows is, I still don't beleive the statement "Linux will not work on my machine". LOL. To get Linux to work on more hardare we need more ppl to use it to make hardware vendors think twice about not crating Linux drivers
Anywho, see if the port works in windows. If it does, we may have to hunt down a good Nvidia LAN port driver for linux for you (or if you are motivated enough u can write one!)
