I recently purchased two used Supermicro servers, model 5015M-T that contain the "PDSMi" motherboard. After loading XP-Pro w/SP3 the Intel PRO/1000 ethernet ports would not pickup the boards MAC addresses. I loaded the newest Intel Network Connections Driver version 14.8, after rebooting same problem, no MAC's. I removed 14.8 and loaded 14.7 just like others have done in this forum, same problem. Then I removed 14.7 and loaded 14.6, rebooted and everything works fine. This motherboard has the Intel 82573V & L PCI Express ethernet. It is also my conclusion the two newest versions (14.7, 14.8, PROXP.EXE) are bad, or at the very least are not compatible with gear that is still current.
Ahh Yesh, Found the same problem, however, have been unable to reinstall any previous versions, W2003Srv SuperMicros PDSBM-LN2+ systems, I agree, there seems to be an issue with the drivers,
