hello, I got a following strange problem - I have an MSI board with nforce 3 250gb chipset, and integrated nVidia LAN - everything is working fine, until I do one thing - disable the LAN connection (as I understand it that is the same as disabling the network adapter). Guess what happens? an immediate bluescreen - everytime I do it, tried WinXP and Win 2000 - results very similar. bluescreen says that error occured in the main driver file, (nvlrm.sys or something like that). Actually, after hours and hours of research and misery, I worked out a simple solution - unplugging the cable instead of disabling the NIC - you may ask why is that a problem, but we had a dumb university network, running with some securew2 client enabling 802.11 authentication over EAP protocol or sth. like that, and this "sofisticated" solution never works - when I turned on the PC, it never authenticated corretly with DHCP server, and the only way to connect was to re-enable the LAN connection (that was a problem of many other students). I ASK, DO YOU THINK IT'S A FAULTY HARDWARE, an IRQ PROBLEM or what ? When I use a PCI NIC, there is no problem - but I prefer the on-board one for obvious reasons. thanks for any valuable suggestions.
