2 3Com NIC in 1 system?

Fellow geeks,

My manager is too chicken to install two NIC's so I decided to give it a shot this weekend.

I have 1 card that is a 3Com EtherLink XL 10/100 PCI (3C905C-TX) card and the other (pre-existing card) is 3Com EtherLink XL 10/100 TX NIC (3C905B-TX) card. The 905B has been running in my system for some time. I decided to add the 905C today. It decided to share an IRQ with my video card so I had to move it and got one of those IRQL_NOT_LESS_OR_EQUAL to minidumps because I forgot to ditch the old settings it installed. I took care of that in safe mode. Then it decided to do that every time I opened my browser. I took care of that by running IE setup again. All is fine now.

Here's the question part, it seems like it is only using the 905B card. The 905C shows up fine but the number of packets received and sent doesn't come close to the number of packets 905B manages. How do I get them to share the load? How do I get them to share the packet load like two processors can share loads? Or is it possible? I know someone out there has achieved getting two network cards to run together in some form.

Below are my machine specs:

Windows 2000 Professional with Service Pack 2 + updates, Tyan S2507 Tiger 230 mobo + via updates, dual 1 GHz PIII 133 processors, 512 MB of pc133 SDRAM, 3D Prophet II video, and one of those "crappy" Creative Sound Blaster Live XGamer 5.1 card (yes it makes those awful noises every once and a while:). Also, all is on its own IRQ with 905B residing on IRQ 17 and 905C residing on IRQ 18.

On both cards, I use “Client Service for Microsoft Networks”, “Client Service for NetWare”, “File and Printer Sharing for Microsoft Networks”, “Network Monitor Driver”, “CommView Network Monitor”, ”NWLink NetBIOS”, “NWLink IPX/SPX/NetBIOS Compatible Transport Protocol”, and “Internet Protocol(TCP/IP)” to meet my networking needs.

I should also mention that I use 802.3 for the frame type on both but the only difference between the two is 905B has a static IP while 905C has a dynamic IP.

In “adapters and bindings”, under "Advanced Settings" it has the 905C listed first in "Connections are listed in the order in which they are accessed by DNS and other network services". But it seems like the 905B adapter only manages traffic.

My nodes I jack into with a 2 CAT5 TP RJ-45 cables are 100 mbps nodes under ideal conditions. If I get these two cards running, with each holding its own IP, each could possibly have 100mbps? Or am I going about this wrong?

If anybody has any advice for me that would be great! I'm all ears.

Thanks in advanced,

MrvNDMrtN,

I just installed that service. Thanks.

I got another one of those 0xD1 BSOD's. Its making me wonder if these two cards are able to run side by side. Maybe after installing the QoS that should go away.

Thanks alot,
