LV-67C Specifics

The assembling of new Gen 3 LV-67C based orbit node may have 3 major components.

How to Assemble the Case

There are a few considerations when it comes to the assembly of the LV-67C.

  1. The LV-673 has the mini-PCI slot mounted on the bottom of the motherboard. This means that when assembling the node it is critical to install the cards and pigtails onto the node before installation into the case, as the bottom will be completely inaccessible.
  2. Connect all the pig tails and route the wires to the right side (facing the rear) of the motherboard.

Flash The LV67-C bios

Make A USB Flash disk.

Building a flash drive to update bios on LV motherboards

How to build the USB boot stick:

You will need:

  1. Bios Image (Board Specfic)
  2. Rufus Utility, downloadable here

NOTE: The tools and bios files for the LV-67X line are located on the archive(Windows share: \\archive2\pub\Archive\PC\Bios)

To Create the USB Flash Disk:

  1. Run the Rufus utility
  2. Choose options to make the usbflash disk freedos bootable
  3. Once complete remount the flash disk and copy the folders containing the update utilities for the motherboards you need to update

This disk should now be capable of Flashing your bios.

In the LV-67B bios (and I suspect others in the LV line), the flash disk can be put into 1 of 3 modes USB-FDD, USB-HDD, AUTO. The Auto mode guesses either FDD or HDD. When in the FDD mode the bios treats the flash disk like a floppy. This mode DOES NOT work with the tools for building a USB flash Drive. The HDD mode does work. To use this mode however, you need to specify Hard disk as the booting device and the modify the Hard drive boot order to put your USB Flash disk first.

First Gen:

  1. Remove the lv-67c kit from it wrapping, Attach the pcm-cia and mini-pice cards (As below).
  2. Attach the video card assembly as prior
  3. Power On and listen for the post beep. Hit Delete immediately after. The screen setup will usually lag the input so you will have to hit the button before you can see the prompt.
  4. Once in the bios, goto the boot order menu and do the following:
    1. Disable the USB FDC: (select it and press x)
    2. Enable the USB HDDL SanDisk Cruzer Micro-(USB
      Enable the SanDisk USB cruzer drive in boot menu
    3. Save and exit
  5. Save and exit the system will power down. If left alone it will power back up and proceed to boot from the USB disk.
  6. After the post, in the serial console you will see the kernel boot messages pass by
    1. NOTE: The first time it boots from USB it will complain about the file system needing a check. Choose i to ignore this and let it finish booting.
  7. Once booted, login and issue a sudo poweroff command.
  8. Remove the video card and replace it with the Ethernet card. Disconnect the KVM usb cables.
  9. Power up again, it should still boot into the serial console and you will eventually get to a login prompt.
  10. Log in then issue this command
    sudo nvramtool -B lv67c_2011-8-29.bios
  11. The bios is now configured. Reboot once more and check the serial console for bios boot messages. It should try to pxe from the leftmost interface (verify the mac address).

Second Gen:
The second batch of LV67C motherboards do not need to have their bios flashed, only reconfigured.

  1. Attach requisite cables and Cards
    Attaching Video Cable and USB stick
    • Serial Cable
    • Video card with monitor cable attached (Do not use the onboard VGA)
    • Ethernet cable into Leftmost port
    • 24 pin and 4 pin power headers
    • Keyboard
    • Standoffs to prevent shorts
  2. Once the box has Posted (the beep) press delete quickly to get into the bios
  3. Adjust the following bios parameters
     Boot Features
       Halt on [No errors]
       Boot Time Diagnostic Screen [Disable]
     Advanced Chipset Control
       On Board Lan N Boot PXE Rom [Enabled]
     Console Redirection
       Com Port Address [Enabled]
       Baud Rate [155.2K]
       Continue C.R. after Post [On]
    Disable Halt on ErrorsEnable the Lan RomEnable Serial Console Redirection
    Note The N in Lan Rom refers to the Interface Number. If making a Gnu radio Node the device names will be shifted due to the additional NIC card. Thus the left most NIC will be eth1 which corresponds to Lan 1. If making a regular node then Lan 2 will be eth1 and only that rom should be enabled.
  4. Save these settings and exit. Once saved the node will power off and then back on again to "apply" the settings changes. You can unplug the node after the initial power off or let it reboot and then poweroff. You should be seeing output on the serial console now.
  5. Once powered off, remove the video card and attach the nic card (if needed). Connect the ethernet cable that carries Outdoor control vlan to the designated eth1 interface.
  6. Power on the node and hit del again to get back into the bios.
  7. If making a USRP node, in the boot menu choose the IBA GE slot 0100 v1321 boot item and exclude it from the boot sequence.
  8. Depending on node type you will see an item labeled IBA GE slot xxxx v1324. Where xxxx is the hex address for the device (e.g. 0900 for Lan 1). Set this device to be #1 in the boot sequence. Save and exit.
    Bios Boot Sequence Screen
  9. The node should now attempt to boot from pxe and if dhcp and tftp are setup correctly, the node should be able to boot into the pxe image.
