    Wake-on-LAN (WOL) for System76 lemu2?

    My System76 Lemu2 has this version of Phoenix BIOS:
    CALPELLACRB.86C.0000.X.0000000000

    I called System76, and this is the most recent BIOS for the Lemu2, but unfortunately the BIOS doesn't support WOL. (Or does it?)

    How do I get WOL functionality? I've tried
    Code:
    suduo ethtool -s eth0 wol g
    but to no avail.

    Thanks

    Have you entered the BIOS menu to check if it supports? You should start there...

    Yes, there is no power management menu in my BIOS menu, thus there is no ACPI WOL feature

    echo 0 > /sys/class/rtc/rtc0/wakealarm ;  echo `date '+%s' -d '+ 2 minutes'` > /sys/class/rtc/rtc0/wakealarm ;   /usr/sbin/pm-suspend
    , but it didn't wake after 2 minutes.

    Thanks again

    Our laptops don't feature wake on LAN capability. For that, you would need to go with our Desktops.

    Are there any free BIOSs for Intel(R) Core(TM) i3 CPU U 330 @ 1.20GHz that I could try? Thanks

    BIOSs are specifically developed for each motherbaord, and are not interchangeable. There are no other BIOSs that are compatible with your Lemur.

    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.

    Not even CoreBoot?

    I know my LemU2 has an Intel(R) Core(TM) i3 CPU U 330 @ 1.20GHz CPU and an Intel Corporation 82801 Mobile PCI Bridge, which this page says CoreBoot v4 supports. However, when I run make menuconfig for CoreBoot, there is no option for "CLEVO/KAPOK Computer Device 3100". Perhaps CoreBoot does not support CLEVO/KAPOK boards?

    Thanks

    No, our systems do not use a Clevo BIOS.

    Coreboot (and any other BIOS) has to be developed to support a specific motherboard. Many computer companies use more than one motherboard in even the same laptop model, and many of them use highly proprietary BIOSes in the first place, which makes developing Coreboot for them extremely difficult. Most of the systems Coreboot supports are desktop motherboards, and with all the laptops available out there, it's no wonder they haven't developed support for ours yet.

    BIOS support is much more complex than OS support. You can't develop for one specific CPU, chipset, PCI controller, etc. You have to develop for an entire motheboard (since the BIOS handles all low-level communication between hardware and software). If a particular component isn't supported within the BIOS, then that component won't be available to the OS (at best), and the entire system could end up unstable or permanently broken (at worst). In short, the number of BIOSes available for any given system is usually one; the manufacturer's.

    Cool Re: Wake-on-LAN (WOL) for System76 lemu2?

    Dang. The only time WOL really makes sense is for a laptop. You don't have to stress the case and your back opening it to turn it on when using an external monitor and keyboard. My desktops are either "on all the time" or not, and if they're not I sure don't want them turning on by themselves! Laptop's another matter though. Maybe I could rig up some kind of external button...
