Hi,

	I noticed that you have a Dell Precision 410 workstation. I run
several of those (25 of those in fact) as a cluster for our research
group: 

		http://cocoa.ihpca.psu.edu

They have been running great! If it be of some use to you, you can
download the kernel I use from:

	http://bart.aero.psu.edu/linux/vmlinuz_latest

Although this is a somewhat older kernel (2.0.35 #18), it works perfectly
with all the hardware (I had struggled quite a bit with this a couple
of months back to get everything right). My 3c905B runs at  100 Mbps
full duplex without any problems whatsoever (in fact I have two of these
on my server which is also a Dell 410).

| Last week I tried to install redhat 5.2 on a Dell Precision 410.  This

| network when the system was started.
| 
| After trying a lot of things, it seemed that the adapter was configured as

| the problem disappeared.
| 
| Because the problem didn't appear with NT (I installed NT again on the
| machine to test it; I wanted to know if it was a hardware or a software
| problem), I think this may be called a bug in the Linux driver.
| 
| I hope this information may be useful.
