Hello, Perhaps someone here can help me. I recently purchased a Tyan Tiger MPX (S2466N) dual-athlon board, with on-board 3c920 NIC. I have been having difficulty getting multiple Tulip (DC2114x) NICs to work with this board. First, I had ordered a DLink DFE-570TX quad-channel DC21143 board to run on the server. Using both the dc and de drivers, I have beeing experiencing issues where the device doesn't appear to be delivering interrupts properly. The card does work perfectly fine on my UP EPoX 8K7A+ (AMD-760) motherboard at home. Thinking that it was perhaps a compatibility issue between the board and the bridged card (PCI-PCI DC21152 bridge), I went out and got four Asante FriendlyNET DC21140AF NICs for the system (cards I use at home). The problems persist. Anyway, I am not extremely familiar with the inner-workings of the MP spec and APIC-based hardware, and am at a loss as to what is going on. Unfortualtely, this board doesn't provide many PCI tweaking features in the BIOS, like Slot-INTPIN assignments, IRQ-PIN assignment, etc... BTW, this is running 4-stable, which I upgraded to from 4.5-R, to get the ATAPI and AMD768 support. 4.5-R experienced the bad behavior, though. I have the mptable, dmesg, and pciconf -l output if anyone could help me with this. -- coleman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
