SmartFirmware
The Open Desktop Workstations (ODWs) use SmartFirmware. The SmartFirmware user manual has good tutorials for a variety of boot configurations.
You can save environment variables in SmartFirmware by editing the nvramrc script.
- To begin editing, type
nveditand make any desired changes. - Use the commands below to navigate the editor; arrow keys do not work.
- control-e - end of line
- control-n - next line
- control-f - forward
- control-b - back
- control-c - exit
- When finished, hit control-C to exit the editor.
- Finally, type
nvstoreto save your changes.
Netbooting
The DHCP support in the firmware is slightly buggy and requires inserting a client and server IP of 0.0.0.0 in the boot-device string, like so:
setenv boot-device eth:dhcp,0.0.0.0,,0.0.0.0
(The double comma indicates an empty boot file name--it is supplised by the DHCP server.) eth is an alias for the 100Mbit ethernet device and geth is an alias for the Gigabit device. Now to boot, simply type boot and hit return. The red cables are hooked up to the 100baseT interfaces, and the yellow ones are hooked up to the 1000baseT interfaces.
Booting from disk
The current working boot configuration is as follows:
boot-device = hd:0 boot-file = /boot/vmlinuz-2.6.8-powerpc root=/dev/hda1 console=ttyS1,115200n1
You can modify these variables using the setenv command; optionally saving them in nvramrc according to the above instructions.
