yaVDR 0.3.0a & Asus M3N78-EM: NVRAM-WakeUp Howto

Update 2010-12-27: I’ve published a step by step instructions how to use ACPI for automatic wake-ups for an Asus M3N78-EM mainboard and yaVDR 0.3.0a. The ACPI method is easier to setup and does not need an additional reboot.

Here are the step by step instructions to set up NVRAM-WakeUp for an Asus M3N78-EM mainboard and yaVDR 0.3.0a:

  1. Enable “Power On By RTC Alarm” in the BIOS settings (Power > APM Configuration).
  2. Create the file /etc/nvram-wakeup.conf with the following content:
    ################################################
    ##  Mainboard autodetection information:
    ##
    ##    - Mainboard vendor:   "ASUSTeK Computer INC."
    ##    - Mainboard type:     "M3N78-EM"
    ##    - Mainboard revision: "Rev X.0x"
    ##    - BIOS vendor:        "American Megatrends Inc."
    ##    - BIOS version:       "0511"
    ##    - BIOS release:       "01/13/2009"
     
     
    /etc/nvram-wakeup.conf
    need_reboot      = ON_ANY_CHANGE
     
    addr_stat        = 0xDD          # Status byte
    shift_stat       = 3             # The position of the status bit in the byte
     
    addr_day         = 0x8C          # Day
    addr_hour        = 0x8D          # Hour
    addr_min         = 0x62          # Minute
    addr_sec         = 0x63          # Second
     
    addr_chk_h       = 0x30          # High checksum bit
    addr_chk_l       = 0x31          # Low checksum bit
     
    upper_method = VT82Cxxx
  3. Create the following custom templates (you may have to create the directories under /etc/yavdr/templates_custom):
    1. /etc/yavdr/templates_custom/etc/vdr/vdr-nvram-wakeup.conf/10_enable-nvram
      ENABLED="yes"
    2. /etc/yavdr/templates_custom/etc/vdr/vdr-nvram-wakeup.conf/20_commandline
      COMMANDLINE="-C /etc/nvram-wakeup.conf --directisa"
    3. /etc/yavdr/templates_custom/etc/vdr/vdr-nvram-wakeup.conf/30_specialshutdown
      SPECIALSHUTDOWN="/usr/sbin/grub-reboot PowerOff ; /sbin/reboot"
    4. /etc/yavdr/templates_custom/etc/vdr/vdr-nvram-wakeup.conf/40_force-reboot
      FORCE_REBOOT="yes"
  4. Rebuild /etc/vdr/vdr-nvram-wakeup.conf::
    # sudo process-template /etc/vdr/vdr-nvram-wakeup.conf
  5. Use the yaVDR web frontend to set the “VDR Shutdown” method to “reboot “PowerOff” kernel“.

Instructions to synchronize the system clock and the hardware clock can be found in Appendix A in my post “Ubuntu 9.10 & Via Epia-M1000B: Setup NVRAM-WakeUp to wake up VDR“.

    Hi,

    doesn’t ACPI Wake-Up work on this Board?

    Besides this: What Shutdown Method are you using?
    Have you tried S3?

    Greetings,
    Hendrik

    Hi Hendrik,
    as described in Step 5, my shutdown method is “reboot ‘PowerOff’ kernel” because the NVRAM wake-up needs a reboot for this mainboard. IMHO this mainboard should also support ACPI wake-up and I think, I’m going to give it a try in the near future.
