PCI 1.0 Gigabit Ethernet Nics

Does anybody know of any PCI 1.0 Gigabit Ethernet Nics. I got an old lga 775 mobo laying around and I'm going to mod it into a Pfsense router with a lga 771 processor hack.

Bought one of those for my pfsense router. Works great.

One thing to keep in mind is that that all of the PCI slots share 1.3gbps of bandwidth which means that if you have more than one you are limited to a total speed of 1.3gbps. I'm not sure if up and down speed are separate either.

But yeah you can get them cheap and they work okay if you don't need the speed. If you look on ebay there are pci-x cards which may or may not work on your board, probably best to avoid them if you're unsure.


I can confim on X38 LGA 775 works flawlessly for me.

Yeah. One at a time, half-duplex.

Conceptually, the PCI Express bus is a high-speed serial replacement of the older PCI/PCI-X bus.[6] One of the key differences between the PCI Express bus and the older PCI is the bus topology; PCI uses a shared parallel bus architecture, in which the PCI host and all devices share a common set of address, data and control lines. In contrast, PCI Express is based on point-to-point topology, with separate serial links connecting every device to the root complex (host). Due to its shared bus topology, access to the older PCI bus is arbitrated (in the case of multiple masters), and limited to one master at a time, in a single direction. Furthermore, the older PCI clocking scheme limits the bus clock to the slowest peripheral on the bus (regardless of the devices involved in the bus transaction). In contrast, a PCI Express bus link supports full-duplex communication between any two endpoints, with no inherent limitation on concurrent access across multiple endpoints.

So with a 2 Port nic I would be getting like 650 mbps and for a 4 port Nic I would be getting about 325 mbps for each port. I can live with that. I'm thinking this here fellow. I have an old psu and a hard drive(cached networking drive thingey) all I need is 64 GB ssd for pfsense and some cobbled togethor I/O and case. Perfectly affordable pfsense box.
