Installing a 3Com 3C905B-TX

I'm having trouble insatalling a 3C905B-Tx in an NT Server.  When I install the NIC, the installation process appears to go okay, but then it runs the diagnostics, which fail.  The node address is reported as all zeros and all the diags fail. 3c90xcfg reports that no adapter is installed.  I've downloaded the latest drivers from 3Com.

I've swapped the NIC with one from a Windows 98 machine.  It works fine in the W98 machine and the one from the W98 machine still fails in the server.  I've also swapped PCI slots with the VGA controller.  This would appear to eliminate hardware.

The server hardware is a Micronics Spitfire EX with dual 300Mhz PII cpus and the software is Winnt4.0 service pack 1.

I would get service pack 3, even if it is not determined that service pack 1 is the cause of the NIC problem.

Thanks estest, I'm in the process of doing that.  The only problem with that is, that I have another machine at another site with the same configuration that works.  Also service pack 1

You really need to install SP3 and download the newest 3com drivers!

I've installed SP3 and still have the same poroblem.  Could it be something to do with plug n play in my CMOS setup?

As previously mentioned, apply sp3.  Also, make sure that the drivers that you have are version 3.1.  For NT you only need the second diskette from 3com and make sure that you point to OEMsetup.inf, not w95el90x.inf.  You should also reapply sp3 following NIC installation and everything eill work.

You must disable plug and play in BIOS and ensure you are using 3Com 3.1 drivers

I was using 3Com 3.15 drivers, but the trick was disable plug'n'play in the BIOS.  Thanks RatBag
