How to Deconfigure a Device Manually
To support a degraded boot capability, the OpenBoot firmware provides the
asr-disable
command, which lets you manually deconfigure system devices. This
command “marks” a specified device as disabled , by creating an appropriate “status”
property in the corresponding device tree node. By convention, UNIX will not
activate a driver for any device so marked.
What to Do
1. At the
ok
prompt, type:
where the device-identifier is one of the following:
■
Any full physical device path as reported by the OpenBoot
show-devs
command
■
Any valid device alias as reported by the OpenBoot
devalias
command
■
Any device identifier from the following table
Note –
The device identifiers above are not case-sensitive; you can type them as
uppercase or lowercase characters.
