Hi, Thomas!
I don't know if this can be any useful to you, but...
According to
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-60400your NIC is listed as "Integrated Intel Gigabit Ethernet with Intel 82573E".
The "Network adapters" page in the "Hardware" section of eComstation.ru website has an entry that lists 82573e as unsupported, but no updated news since then (2005):
http://en.ecomstation.ru/hardware.php?action=item&id=626Now, this very chip is discussed in this thread
http://osdir.com/ml/netlabs.genmac.user/2006-09/msg00063.htmlSince last post was from Adrian Gschwend who asked for PCI ID, MAYBE support for this chipset was integrated into some GenMac release.
You may also want to try the NICPAK package by Chuck McKinnis (
http://www.os2warp.be/index2.php?name=nicpak ), but the Intel package there apparently comes with the same drivers as those pointed to in the above netlabs.genmac.user thread (i.e.
http://osdir.com/ml/netlabs.genmac.user/2006-09/msg00063.html ). Chuck also has his own personal page (
http://www.7cities.net/~mckinnis/os2/ ), where you can also find GENPAK, "a small selective installation utility for the GenMac drivers".
This page:
http://driverscollection.com/?H=PRO/1000%20GT%20Desktop%20Adapter&By=INTEL&SS=OS/2apparently has a link to an OS/2 driver for 82573 NIC, but the package has the same drivers as those included in
http://os2warp.be/nicpak/files/intel.zip .
So, in short (sorry for this probably useless list of sites...):
try some Intel driver first (perhaps the one provided in the NICPAK package); if this doesn't work (and I fear this may unfortunately be your case, according to the reports I found on the net), then try GenMac package (latest public version is at
ftp://ftp.netlabs.org/pub/genmac/ ). If your NIC isn't listed as supported, you might try setting the option "UNSUPPORTED" in the protocol.ini file (IIRC). This may or may not solve your problem, but I don't really know too much about that. Please refer to
http://news.gmane.org/gmane.org.netlabs.genmac.user/ for details. There was a thread about this option some time ago. You might ask in that newsgroup if there's anyone who managed to install the same NIC as yours.
Well, this is all I can do. Hope this helps a bit. Good luck!
