Hi all,

Today I was starting some testes with OLPC using the steps described below.

Install OLPC in USB Disk

” Linux

If you can devote an entire USB flash drive or hard disk for trying images out, using the images is easy.

To try out an image, simply download the appropriate .img.bz2 file, e.g.,

olpc-stream-development-42-20060714_1709-rpm-ext3.img.bz2

unzip it, and transfer it to a USB storage device via dd, e.g.,

# bunzip2 olpc-stream-development-42-20060714_1709-rpm-ext3.img.bz2
# dd if=olpc-stream-development-42-20060714_1709-rpm-ext3.img of=/dev/sdb bs=1M
# sync

Remember to:

* Make sure any old partitions from the storage device are unmounted.
* Do this as the super user / root
* Replace /dev/sdb with the device file of the USB storage device. The images do contain a partition table and boot loader, so make sure to write to the device and not a partition on the device (e.g. not /dev/sdb1)
* The USB storage device must be 1024 MB or larger. All existing data will be lost.

Now you should be able to boot the OLPC operating system off the USB storage device. “

During the boot you will find the problem with the VGA video. Solution below.

“Problem:External monitor reported “Video mode not supported”.

Solution: Using serial port console, change “1200×900″ to “1024×768″ in /etc/X11/xorg.conf and comment out “cp -f /dev/X11/geode-xorg.conf /etc/X11/xorg.conf” in /etc/init.d/olpc-configure for X-window to start properly on an external 1024×768 monitor/ATest board. “
