Compaq DS20E - AlphaStation - 1 GB RAM User Manual page 39

Memory size is determined.
The PCI bridges and attendant buses (indicated as IODn by the console) 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.
