Some riser card can cause problem. But in this case, I think you may be confused 64-bit v.s. 66MHz. The 32-bit card may only work under 33MHz frequency. If your 64-bit PCI slot can detect your NIC PCI CLK, and set its CLK to 33 MHz, the NIC should work. I just tested a Intel 82559 NIC (32-bit/33MHz) on E7500 motherboard. When nothing plugged into the slot, BIOS says it operates at 66MHz. When Intel 82559 NIC plugged in, BIOS says it operated at 33MHz, and the NIC works OK. So, you should check the BIOS info during the boot time. 3COM card may work little different. > 4) Installed SCSI card into a Dell 2550 running FreeBSD4-STABLE. > Same behavior as in colo hardware.
