1.6 Transient Commands CP/M Operating System Manual
For example, the command,
MOVCPM * *
constructs a new version of the CP/M system and leaves it in memory, ready for a SYSGEN
operation. The message
READY FOR 'SYSGEN' OR
'SAYE 34 CPMxx.COM'
appears at the console upon completion, where xx is the current memory size in kilobytes. You
can then type the following sequence:
SYSGEN This starts the system generation.
SOURCE DRIVE NAME Respond with a carriage return to skip the CP/M read (OR
RETURN TO SKIP) operation, because the system is already in memory as a
result of the previous MOVCPM operation.
DESTINATION DRIVE NAME Respond with B to write new system to the disk in drive B.
OR RETURN TO REBOOT) SYSGEN prompts with the following message:
DESTINATION ON B, Place the new disk on drive B and press the RETURN key
THEN TYPE RETURN when ready.
If you respond with A rather than B above, the system is written to drive A rather than B.
SYSGEN continues to print this prompt:
DESTINATION DRIVE NAME (OR RETURN TO REBOOT)
until you respond with a single carriage return, which stops the SYSGEN program with a system
reboot.
