Srm Console Power-Up Display - Compaq ES40CSLP Installation, User & Service Manual

Troubleshooting and Diagnostics
If the SROM code could not find any available memory, you would see a display similar to the
following on the console terminal.

Indicates failed DIMMs
DIMM 2 on MMB1 failed.
š
Indicates that some DIMMs in this array are not the same. All DIMMs in the affected array
are marked as incompatible (incmpat).
›
Indicates that a DIMM in this array is missing. All missing DIMMs in the affected array are
marked as missing.
œ
Indicates that the DIMM data for this array is unreadable. All unreadable DIMMs in the
affected array are marked as illegal.
Finally, you would see the above messages and a final message such as "SROM 0 No Mem" on
the control panel display. In such a case, the system would not come up to the console program.
You would need to replace the bad DIMM sets.

6.5.5 SRM Console Power-Up Display

At the completion of SROM power-up, control is transferred to the SRM console program. The
console program continues the system initialization process. Failures are reported to the
console terminal through the power-up screen or a console event log.
The console program initializes the I/O system, which includes the PCI bus and connected
devices such as SCSI disk controllers, the display device, the floppy drive, and the keyboard.
The display and keyboard devices are initialized first, and then a user interface (UI) is
displayed. As initialization continues, startup messages are displayed within the UI.
Next, a memory test verifies that the memory is fully functioning. After memory is tested, SRM
detects and initializes SCSI disk controllers connected to the computer. As each controller is
detected, SRM probes its SCSI bus and reports each of the SCSI devices that it detects. After
SCSI initialization is complete, Tru64 UNIX or OpenVMS systems display the SRM console
prompt, Pnn>>>. The number indicates the primary processor. In a multiprocessor system, the
prompt could be P00>>>, P01>>>, P02>>>, or P03>>>.
Example 6-2 shows the messages that are displayed once the SROM has transferred control to
the SRM console.
