From: Michael C on 21 Apr 2008 23:24 I've always had a wake on lan on my PC which I use almost daily to wake my home machine up from the office. I upgraded to a bigabyte board but never checked to make sure it had wol. I appears it doesn't. Is there any way with a bit of inventiveness and a soldering iron that I can get WOL to work. From what I understand it's fairly simple and just sends 5V to the board. Can I just get it to trigger the power switch? Thanks, Michael

Like recognizing the "magic packet" format, when seen on the link. You can purchase a LAN card with WOL capability. There are two standards for WOL. If you have an old motherboard, you need to use an old LAN card. The old method uses a cable that goes from the LAN card, to a header on an old motherboard. The new method uses a dedicated signal on the PCI slot called PME. If you find a LAN card that advertises WOL, and yet there is no header on the LAN card, that means the card is using the PME pin on the PCI connector instead. For a PME capable motherboard, you look in the BIOS, as there will be an enable/disable for PME. The LAN card can be plugged into any PCI slot, as the PME signal is bussed to all slots. When you enable PME in the BIOS, that will allow the LAN card to wake the computer. If the built-in LAN chip on the motherboard had Wake On Lan capability, PME was wired up, and then for some strange reason, there was no 3VSB to power the chip, then yes, get out your soldering iron. But is is improbable that they would miss out the simplest thing, and do all the complicated stuff. A bit more research may show you that the capability was there, all along. Maybe if you mention the motherboard model number, it would give someone a chance to read up on it. Paul

It had a gigabit wol card with a wol 3 pin connector to the motherboard. > You can purchase a LAN card with WOL capability. I was thinking of using the one I have and running 5V and ground from the power supply to the 3pin WOL connector on the card. Then I just need to work out what to do with the other pin. Can I wire it straight to the power button or will I need to do more than that? Naturally this is a last resort if nothing else works. > The new method uses a dedicated signal on the PCI slot called > PME.

I would have thought it should be there but I can't find any mention in the manual at all. I've got a spare card that claims to support WOL but doesn't have the 3 pin connector but I couldn't get it to work in my previous PC. Possibly because it didn't have pci 2.2 as you said. I'll give this card a try tonight. > Maybe if you mention the motherboard model number, it would > give someone a chance to read up on it. I don't have the exact model on me at the moment but I'm pretty sure it's this one. The layout is exactly the same as this board but I think mine has a couple of extra SATA ports. http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2630 > > Paul >

The chip supports Wake On Lan. The BIOS has PME enabled by default. All you need to do now, is find the advanced setting for the RealTek chip, and enable WOL in there. http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&ProdID=11 Datasheet for the RTL8111B is here (one of three FTP servers provided by RealTek). AMD Magic Packet and a couple other options are mentioned. I don't know all the various flavors of packet that can be used. Some chips also have a more basic, wake on activity, which is virtually useless for computer applications (because it stays awake a lot). ftp://210.51.181.211/cn/nic/spec-8111b(140).pdf I'd work on some control panels, before warming up the soldering iron.

I had a look through the manual and it appears the motherboard supports PME (page 42 on the link I sent). I have a lan card which I believe also supports PME so I can probably get that to work. It would be handy if the onboard gigabit lan supported wol but searching the manual for WOL or "wake on lan" doesn't produce a single hit. All the PCI slots are full (it only has 3) so I'll have to discard (pun intended) something. :-) Michael |
