I have an older Gigabyte Technology GA-MA770T-UD3P motherboard with an on-board network card described like this:
Model: "Gigabyte Onboard Ethernet" Vendor: pci 0x10ec "Realtek Semiconductor Co., Ltd." Device: pci 0x8168 "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller" SubVendor: pci 0x1458 "Gigabyte Technology Co., Ltd" SubDevice: pci 0xe000 "Onboard Ethernet"
The BIOS of that board is described like this:
Vendor: "Award Software International, Inc." Version: "F12" Date: "03/22/2011"
However that BIOS has an interesting feature: It can determine the length of the wires of a network cable being plugged into the network card (if the other end is "open" (i.e..: not plugged into a switch), and I wonder how that works.
I've seen no other motherboard/networks card/BIOS combination that offers a similar feature, while I wonder: If one network card can do it, aren't all the others able, too?
