Timeslicing, Swapping, Security Code, Session Accounting

Commands to set the timeslicing quantum, the priority swapping boundary, system security code and session accounting can be entered at any point in the boot process (except in the middle of an RP sequence).

QU,timeslice,priority

Set the timeslice quantum to the given value in milliseconds. Set the

 

priority boundary where timeslicing is to begin. If this command is not

 

given, the values are those set at generation.

BG,boundary

Set the boundary where priority swapping is to begin. If this command

 

is not given, the value is that set at generation.

SS,newcode

Change the system security code from the value in the system file to the

 

newcode.

AC[,ONOFFOA] For systems with VC+ only. Turns session accounting on (ON), off (OFF), or on without logoff endofsession information displayed (OA). AC with no parameters turns accounting on. If this command is not given, the session accounting state carries over from the last time the system booted.

Note that the system utility METER uses information gathered by the session accounting system; session accounting must be enabled for METER to function properly.

EN (End) Command

The command input to BOOTEX is terminated with an EN command. The EN command also must be used to terminate the RP phase. Because an end of file or CRLF is interpreted as an EN command, a CRLF can terminate the RP phase as well as command input to BOOTEX. When command input to BOOTEX is terminated, BOOTEX loads the modified system into memory and starts it.
