=== Installation Caveats === |
|||
* '''If you have a B1 system:''' |
|||
# Perform the auto-reinstall procedure at http://wiki.laptop.org/go/Autoreinstallation_image '''before''' upgrading to this firmware version |
|||
# '''DO NOT''' use olpcflash to write new firmware images. Doing so will erase the manufacturing data that was added at the factory. |
|||
* After you reflash, you must power cycle by physically removing power from the system. A warm-start or button-induced restart is not sufficient. Please remove both the battery pack and wall adapter for 10 seconds. |
|||
''ATest users only:'' If you use olpcflash to write this image, you must use the --brick option.<br> Example: <code>olpcflash --brick -w image.rom</code><br> This will update your EC code. |

OLPC Firmware Release Q2B14 - 2006-12-30
This is the first firmware release that is compatible with the Open Firmware filesystem in Linux (which lets Linux read the OFW device tree).
MD5: f8d276b3656818dca04e4e6da11a31f4
Changes since Q2B11
- OFW: Fixed memory reporting problem that caused problems when Linux called back into OFW
- OFW: Sped up page table setup code by running it from RAM, thus shaving a couple of seconds from the OFW startup time.
