Description
Sets the default operating system.
vms or unix—Sets system to boot the SRM
firmware.
Sets a console password. Required for placing the
SRM into secure mode.
Disable or enable parity checking on the PCI bus.
On—PCI parity enabled (default value)
Off—PCI parity disabled
Some PCI devices do not implement PCI parity
checking, and some have a parity-generating
scheme in which the parity is sometimes incorrect
or is not fully compliant with the PCI specifica-
tion. In such cases, the device functions properly
so long as parity is not checked.
Enables fast SCSI devices on a SCSI controller to
perform in standard or fast mode.
0—Sets the default speed for devices on the
controller to standard SCSI. If a controller is set
to standard SCSI mode, both standard and fast
SCSI devices will perform in standard mode.
1—Sets the default speed for devices on the
controller to fast SCSI mode.
Devices on a controller that connects to both
standard and Fast SCSI devices will
automatically perform at the appropriate rate for
the device, either fast or standard mode.
