How to check the OS and firmware versions

  This page is monitored by the OLPC team.

Note:

If you have build Update.1, the information can also be found under the 'XO main menu', in the section called 'About XO'.

Step 1: Operating system (OS)

1. Type Ctrl-Alt-F2 (the F2 key is the same as the Group key ()
2. Read the build number from the first line of text that appears in the console window

Sample transcript:

OLPC build 650 (stream ship.2: variant devel_jffs2)
kernel 2.6.22-20070919.2.olpc.0987654321abcdefabcedf on an i586

The OS build number in the above example is 650.

The Ctrl key has a solid diamond on it (♦); the Alt key has an open diamond on it (♢); . (See Keyboard Shortcuts for more details.)

Step 2: Firmware

su -l
olpc-bios-sig

or

su -l
more /ofw/openprom/model

Sample transcript:

OLPC build 650 (stream ship.2: variant devel_jffs2)
