Operation 3-7
The primary CPU is determined for the last time. The primary CPU unloads
PALcode and decompression code from the FEPROM on the system board to
its B-cache. The primary CPU then jumps to the PALcode to start the SRM
console.
The primary CPU prints a message indicating that it is running the console.
Starting with this message, the power-up display is printed to any console
terminal, regardless of the state of the console environment variable. (If
console is set to graphics, the display from here to the “configuring I/O
adapters…” line is saved in a memory buffer an d printed to the graphics
monitor after the PCI buses are sized and the VGA device is initialized.)
The size and type of each memory DIMM pair is determined.
The console is started on the secondary CPU. A status message prints for each
CPU.
The PCI bridges (indicated as IODn) are probed and the devices are reported.
I/O adapters are configured.
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
DIGITAL 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 Chapter 4 for information about the SRM console and to Chapter 5 for
AlphaBIOS.
