Prime Proprietary Operating Instructions
3.6.1.3 Master Clearing the System
The "SYSCLR" command places the CPU in a known starting position. The
CPU and 1/0 controllers are initialized, all CPU high speed register
file locations are reset to 0, and the Cpu is set to 16S addressing
mode.
The "VIRY" command runs diagnostics to verify the VCP and then
performs a SYSCLR. The following is an example:
ESC_ESC
CP> STOP
CP> SYSCLR
*** CPU VERIFIED ***

3.6.1.4 Booting the System
"Boot" or "bootstrap" automatically loads in pre-boot and loader
routines which then load the desired software. Booting is usually
done from disk. This method is outlined below. Refer to Service
Manual 80 for instructions on booting from a magtape device.
1. Install the appropriate media on the disk device you wish to boot
from. The media must be formatted with BOOT on its first record
(record 0). Wait until the device is cycled-up and ready (on CIC
drives, READY light does not blink).
2. Determine the sense switch settings for the device you wish to
boot from {see Table 3-6). Determine the partition's physical
device number (from FESM #80).
