OpenBoot[tm] PROM (OBP) Commands
Power On Commands
- STOP bypasses POST. STOP-A aborts POST.
- STOP-D forces a diagnostic power on. The NVRAM Parameter diag-switch?
is set to true.
 Not supported by USB Keyboards.
- STOP-F forces input and output to ttya. Input from the Keyboard is
disabled except for L1-A.
Not supported by USB Keyboards.
- STOP-N forces a set-defaults of the NVRAM.
Not supported by USB Keyboards.
With Sun Blade 1000/2000, power on and
wait for the power button LED
to blink and the speaker to beep, then
quickly depress the power button twice.

The upa-port-skip-list NVRAM variable is used to skip probing of UPA
ports. The following UPA ports are used:
| Processors |
UPA Ports 0, 1, 2, and 3 |
| Frame Buffers |

| Psycho |
UPA Ports 4, 6, and 1f |
- ok setenv upa-port-skip-list 3,1d (Skip CPU3 and FFB1)
The pci0-probe-list NVRAM variable is used to control the probe order for
onboard PCI devices (/pci@1f,4000). The probe order for PCI devices plugged into
the backpanel slots cannot be controlled. Devices omitted from the pci0-probe-list
are not probed.
Devices in the pci0-probe-list are:
- 2 = scsi (rma backplane & external connector)
- 3 = scsi (4 disk backplane)
- 4 = Empty slot - Back panel slot 10
- ok setenv pci0-probe-list 3,2,4 (Probe in order 3-2-4)
Due to internal PCI changes introduced in OBP 3.12, the Cheerio node is pseudo-probed
and device 1 must always be included in the pci0-probe-list. Prior to OBP
3.12, an entry for device 1 was not required. The default probe order for OBP
3.12 is 1-3-2-4.
Devices in the OBP 3.12 pci0-probe-list are:
- 1 = Cheerio (flash, nvram, superio, serial, audio, and I2C)
- 2 = SCSI (rma backplane & external connector)
- 3 = SCSI (4 disk backplane)
- 4 = PCI Slot 10
- ok setenv pci0-probe-list 1,3,2,4 (Probe in order 1-3-2-4)
The pci-slot-skip-list NVRAM variable is used to skip probing of PCI devices
plugged into the backpanel slots. If slot 10 is in the pci-slot-skip-list,
it will be skipped even if device 4 is included in the pci0-probe-list.
- ok setenv pci-slot-skip-list 4,6 (Skip slot 4 and 6)
The memory-interleave NVRAM variable controls how OBP sets memory interleaving.
If interleaving is enabled with mixed memory bank sizes, the smaller memory size
is used and POST displays a smaller memory value than is physically installed.
- ok setenv memory-interleave max-size
| Setting |
Description |
| auto (default) |
OBP chooses best setting |
| max-size |
Configure for maximum available memory space |
| max-interleave |
Configure for maximum memory bandwidth (high
interleaving values) at the expense of memory size |
| 1 |
Use 1-way interleaving |
| 2 |
Use 2-way interleaving |
| 4 |
Use 4-way interleaving |
The env-monitor NVRAM variable determines how OBP responds to environmental
monitoring via the I2C serial bus.
- ok setenv env-monitor advise
| Setting |
Description |
| enabled (default) |
Issue a warning and shut down the system in 15 seconds
if an unsafe condition is detected |
| advise |
Issue a warning if an unsafe condition is detected |
| disabled |
Do not monitor for unsafe conditions |

The diag-trigger NVRAM variable is used to control which resets will automatically
enable POST when diag-switch? is true.
- ok setenv diag-trigger power-reset
Run diagnostics on power-on resets.
- ok setenv diag-trigger error-reset
Run diagnostics on power-on resets, fatal hardware
errors, and watchdog resets.
- ok setenv diag-trigger soft-reset
Run diagnostics on all resets (except XIR) including
UNIX init 6 or reboot
- ok setenv diag-trigger none
Does not run diagnostics on any resets.
The asr-enable and asr-disable commands enable and disable system
devices. The .asr command displays the settings.

The disk-led-assoc NVRAM variable defines
the PCI slot location for the dual channel Ultra/Wide SCSI controller connected
to the lower and upper 8-drive backplanes.
The value 0 defines the location of the onboard SCSI controller that connects
to the 4-drive backplane.
The value x defines the PCI slot location of the lower SCSI
controller that connects to the lower 8-drive backplane.
The value y defines the PCI slot location of the upper SCSI
controller that connects to the upper 8-drive backplane.
