This is well documented in the HP Manual:

System Startup, Configuration, and Shutdown
Reference Manual which can be found at this
location for version 7.5.

Snippets of interest are:

The SYSSTART file must be created by MANAGER.SYS and needs
to reside on LDEV 1 to function properly. Once
the file is created, use the following commands to copy the
file to the appropriate location:
:HELLO MANAGER.SYS
:FILE SYSSTART;DEV=1
:FCOPY FROM=tempfilename;TO=*SYSSTART;NEW

If an error exists in the SYSSTART file, the startup process ignores
it and continues execution.
