OQO Configuration:

External Sources:

• Handtops.com
• Ubuntu on OQO

• Screen Rotation works as described on [1]

External Monitor:

The external monitor unter GNU/Linux works fine and can be changed with the OQO Display Tool. Nevertheless the keys Fn video does not work to change the OQO display.

Mouse and Powermanagement:

udev must be running to support the tracpoint and powermanagement functions.

Powerlevel:

Using the kernel from the OQOLinux enables the powerstepping functionality. The OQO will switch to 33% if it is idle.

The maximal powerlevel can be controled with longrun. Make sure that the modules cpuid and msr are loaded.

Setting up Grub for dual boot System:

Since the OQO overwrites the MBR everytime time Windows is started you can set up a dual boot system, adding grub to the windows boot loader. There are two possibilities. You can use an image of the GNU/Linux Grub or use the Windows Grub.

GNU/Linux Grub:

Configure grub:

After you set up your grub config (/boot/grub/menu.lst) which should look something like

timeout 5
default GNU[[/Linux]]

title GNU[[/Linux]]
root (hd0,5)
kernel /vmlinuz root=/dev/hda6 resume=/dev/hda5
initrd /initrd.img

title Windows XP
chainloader (hd0,0)+1

do a

grub-install /dev/hda2

to install grub so the root partition of your GNU/Linux distribution.

Get grub image:

Get an image of the mbr of that partition with

dd if=/dev/hda2 of=grub.bin bs=512 count=1

and save it on an extern disk or host in order to copy it to your windows partition.

Integrate grub into Windows bootloader:

• Copy the grub.bin to C:\

• Make the C:\boot.ini writable with

ATTRIB -R -H -S C:\boot.ini

• Edit the c:\boot.ini and set the timeout to something larger than 0.
• and add a new line c:\grub.bin="Linux" as seen below.

[boot loader]
timeout=5
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons
c:\grub.bin="Linux"

• Change back the rights of C:\boot.ini

ATTRIB +R +H +S C:\boot.ini

Note: Make sure that you remove and add the writelock of the c:\boot.ini from the same comandshell.

---

Windows Grub:

If you don't want to get the grub images and copy it to the Windows partition you can use the Windows Grub.

Integrate grub into Windows bootloader:

• Make the C:\boot.ini writable with

ATTRIB -R -H -S C:\boot.ini

• Edit the C:\boot.ini and set the timeout to something larger than 0.
• and add a new line C:\boot\stage1="Linux" as seen below.

[boot loader]
timeout=5
default=C:\boot\stage1
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons
C:\boot\stage1="Linux"

• Change back the rights of C:\boot.ini

ATTRIB +R +H +S C:\boot.ini

Note: Make sure that you remove and add the writelock of the C:\boot.ini from the same comandshell.

Configure grub:

Open a command shell (Start -> Run and enter cmd) Go to C:\boot if you unpackt your Grub there (default).

Set up your menu.lst as you would for the GNU/Linux Grub.

Do a

grubinstall.exe -m menu.lst

to install grub.

Wireless LAN

The wireless LAN on the OQO was so far unreliable under linux and only worked when windows was booted before and a warm start was used to boot linux. Aparently this changed since Mai 2nd: [Posting on handtops]

Psinewave: I didn't notice it mentioned in this thread but it looks like the current CVS version (2006-05-03) of the Berlios Atmel at76c505a wireless LAN driver is now stable on the OQO 01+ with Fedora Core 4 and a reasonably standard (apart from the Transmeta stuff) 2.6.15 kernel ... I've had it sitting on my desk pinging away with SSH sessions for a couple of hours without dropping any packets ... the only change I needed to make was to add the vendor and product IDs (1557:0002) as mentioned in the original post.

Tom: I got the new WLAN driver running on our machine. Everything looks fine.

Use the kernel module usbvnet5A.

Update: According to tom, there is a problem with the driver on OQO 01. 01+ seems to work fine. --Kenn 15:11, 12 December 2006 (CET)

Power Button

Edit /etc/acpi/events/powerbtn to halt.

Ethernet

The OQO 01+ has a different Ethernet module than the OQO 01. I patched the rtl8150.c to include the product id 7720, but it does not work.

Does anybody have a solution to this problem?

Update: according to http://www.handtops.com/forum/752/4//OQO_Linux_Installation_amp_Configurati.html# there is a driver called "asix" that can be patched with the 1557:7720 vendor and product id to make the ethernet work on the oqo 01+. The driver is contained in the current 2.6.19 kernel, but not in the 2.6.10-oqo-5 kernel. --Kenn 15:54, 12 December 2006 (CET)
