In progress. Rough outline
How you update the firmware depends on what method you can use and what board type you have.
Finding your current firmware version
The version of the firmware is displayed by OpenFirmware when the laptop boots and prior to loading the kernel. The version number is a series of 5 digits after the text
OpenFirmware CL1
An example would be 'Q2B74'. The last 3 digits of this string (B74) are the most important. The 'B' stands for BTest and indicates the target board for the firmware. We try hard to keep backwards compability so it will (with a few exceptions) run on an ATest board.
The 2 digits are the revision number of that firmware. Higher numbers equal more recent firmware versions.
BTest Upgrade
This is the procedure for B1 and B2 boards. The ATest procedure is here
- Using the auto updater - Manual upgrade. - Insure battery and AC. - put on a key - flash
