BIOS setups

Enabling USB

WRAP-Boards with 5V Input

Normally the WRAP-Boards have 12V Input. Anyway, we have one device where the input voltage has been changed to 5V. To enable USB support for this device you must:

1. connect USB adapter board to the WRAP-Board
2. enable USB support in the BIOS of the WRAP-Board:
   1. press "S" during memory test when the WRAP-Board boots up to enter the BIOS
   2. If the menu says "(U)" then this means USB is disabled. Brackets "(U)" mean disabled, and stars "*U*" mean enabled. Press "U" to enable (*U*).
   3. Press "Q" to quit and the answer Yes to save the settings.

Example

Here the USB is disabled in the BIOS, because it is enclosed by Brackets (press U to change this):

(9) 9600 baud *3* 38400 baud (5) 57600 baud
*C* CHS mode (L) LBA mode
(E) Etherboot enable
(U) USB enable
(D) Conservative DRAM timing
*R* Serial console enable
(X) Xmodem upload (Q) Quit

Upgrading BIOS

Goal: After the upgrade of the BIOS the WRAP-Board will have the following order of devices it will try to boot from:

1. If a CF card is inserted, then boot from this
2. Otherwise try to boot from Network (PXE / Netboot)

BEWARE: A failed/wrong BIOS upgrade might brick the WRAP-Board -- so use at your own risk!!!

On Debian Etch 4.0 (probably the same for Ubuntu) you need the following packages for this: minicom lrzsz It probably also works with any other terminal program that supports sending files with xmodem. Here is a minirc.wrap.conf for minicom (save as /etc/minicom/minirc.wrap.conf and start minicom with minicom wrap.conf to connect):

1. press "S" during memory test when the WRAP-Board boots up to enter the BIOS
2. press "X" to send the new BIOS via xmodem
3. press CTRL+A then S to get to the Upload menu of minicom. Select "xmodem".
4. select the file wrap2.upd (can be found here, md5sum is at wrap2_upd.md5sum. Hint: press space bar twice to navigate into directories within minicom)
5. wait until file upload completed
6. Remember to enable USB and Etherboot thereafter! Then press "Q" to quit and save the options.
