Troubleshooting 2-7
By the time the power-up display is completed,
1.
the CPUs have run their self-tests,
2. the SROM has completed its preliminary tests and loaded the SRM console from
flash ROM on the TIG bus into memory,
3. the SROM has passed control to the SRM console,
4. the SRM has polled the system, run its system diagnostics, and has sent the
display characters.
If the system’s operating system is NT, you will not see any of the power-up display
before the line that says “Testing the System.”
➊
Memory size is determined by the C-chip.
➋
The PCI bridges and attendant buses (indicated as IODn by the console) are
probed and the devices are reported. I/O adapters are configured. At a
minimum, the devices are responding to probes by the console program.
➌
The system, disks, and network are tested by the console.
➍
The SRM console banner and prompt are printed. (The SRM prompt is shown in
this manual as P00>>>. It can, however, be P01>>>. The number indicates the
primary processor.) If the auto_action environment variable is set to boot or
restart and the os_type environment variable is set to unix or openvms, the
Compaq Tru64 UNIX or OpenVMS operating system boots.
If the system is running the Windows NT operating system (the os_type
environment variable is set to nt), the SRM console loads and starts the
AlphaBIOS console.
Refer to Chapters 4 and 5 of the AlphaServer DS20 User’s Guide for
information about the SRM console and AlphaBIOS.
