Wake-on-LAN (WOL) for System76 lemu2?
 
My System76 Lemu2 has this version of Phoenix BIOS:
CALPELLACRB.86C.0000.X.0000000000
I called System76, this is the most recent BIOS for the Lemu2, but unfortunately the BIOS doesn't support WOL.

How do I get WOL functionality? I've tried
Code:

ethtool -s eth0 wol g
but to no avail.

Thanks

"BIOS doesn't support WOL."

I guess you could look to an open bios but I still doubt that will fix it.

WOL and acpi/apm and motherboard and power supply and nic all have to support wol.

Are you sure it doesn't support WOL?!?! If you enable PXE booting, you may find that options to WOL kind of "magically" appear, like drives often do when you have them plugged in at boot...

The only other thing you can try is to set the BIOS to wake from a power-off situation and rig a way to turn on power to the machine, such as with a Z-wave enabled appliace adapter.

That,... or just sleep the machine all the time and figure out some way to initiate un-suspend by LAN.

I get the feeling that a tech from system 76 told you this.

" Re: Wake-on-LAN (WOL) for System76 lemu2?
Our laptops don't feature wake on LAN capability. For that, you would need to go with our Desktops."

Coreboot, e.g., doesn't support my chipset.

I'm sure I can get WOL working (somehow) :)

How do I enable PXE booting? Thanks

I'm pretty sure it was a Sys76 tech…

My Bios is a proprietary Phoenix Tech BIOS. I hear theirs are bare-bones and junk.

JaseP 09-27-2012 10:15 AM

For PXE booting,... look under either the tab for boot settings or advanced chipset features in the BIOS... Hunt around...

My ASUS EEE PC 702 (8GB SSD) from 2007 (or so) has Network/PXE booting capability,... I'm sure that more modern laptops would too, unless it's been crippled...

My LemU2 uses a CLEVO 3100 subsystem. The CLEVO manual for it says, on PDF pg. 197, that it supports WOL, even with the Phoenix Tech BIOS.

As you posted the specifications indicate that the computer supports WOL but did not find anything in the manual under the BIOS section where it is mentioned on shown in a set up page.

So how are you sending the magic packet? Are you using the correct MAC?

Also, it is possible that WOL is only supported in certain states. One of my HPs only wakes up from S4 i.e hibernation.

My dd-wrt router sends the packet.

Do you have another computer available to test WOL?

wakealarm

Yes, I'll try it, but I'm pretty sure the problem is my laptop. I set /sys/class/rtc/rtc0/wakealarm to 2 minutes into the future, but after 2 minutes after going into suspend, it didn't awake.

I do not remember reading anything in the manual about BIOS alarm functions which is different then WOL. Try send a magic packet from a different computer on the LAN other then the router and post back.
