Using the OpenBoot Diagnostics
OpenBoot is an industry standard (IEEE1275) ROM-based firmware
implementation that controls your SPARCbook between the time it is
powered on and the Solaris operating system takes control. During this
time OpenBoot carries out the hardware testing and initialization before
booting the operating system.
OpenBoot also provides a user interface and programming language,
based on Forth, which can be used to perform diagnostics and change
user-configerable options stored in NVRAM.
Displaying the OpenBoot user interface
Display the OpenBoot user interface as follows:
1.
Power on your SPARCbook.
2.

Checking SCSI devices
To check whether your SPARCbook can communicate with SCSI
devices, enter the following command:
ok
probe-scsi
This produces a list of SCSI devices attached to your SPARCbook.
On SPARCbook 3 models, the list should include the internal disk (if
fitted) at target 3, and any external SCSI devices. On SPARCbook 3000
models, only external drives are listed.
