- SYSLOAD: HI command
- Loads a dynamically loadable device driver or user job as
- a child job of the HI. The driver or job remains resident
- in memory until the system is reset.
-
- SYNTAX:
- sysload [poolmin, poolmax] pathname [driver-params]
-
- PARAMETERS:
-
- poolmin
- A decimal number specifying the minimum allowable
- memory pool size for the job being loaded, in
- K-bytes. The default is 296K. Do not follow the
- number with the character K, and do not use
- hexadecimal or octal numbers.
-
- poolmax
- A decimal number specifying the maximum allowable
- memory pool size for the job being loaded, in
- K-bytes. The default is 16 Mbytes (0FFFFFH). Do
- not follow the number with the character K, and do
- not use hexadecimal or octal numbers. For use with
- himem, poolmax should be equal to poolmin.
-
- pathname
- The fully specified pathname of the driver or job
- to be loaded. The pathname must begin at the root
- directory (for example, /rmx386/drivers/ramdrv); it
- cannot be relative to your current working directory.
-
- driver-params
- Parameters specific to the driver being loaded.
- These may be optional, depending on the driver or job.
- The syntax of any parameters is defined by each driver
- and I/O job; sysload passes the parameters without
- interpreting them.
-
- ADDITIONAL INFORMATION:
-
- A loadable device driver is a device driver built as an HI
- command. Because you load the driver while the system is
- running, rather than configuring it with the ICU, you can
- dynamically change driver configuration.
-
- Loaded jobs are user applications that can be added to the
- operating system in a semi-permanent fashion. Once the job is
- loaded with the sysload command, the job remains part of the
- operating system until it explicitly exits or until the system
- is rebooted.
-
- Typically, you only load a driver or job once each time the
- system is started. The loaded driver is not deleted even after
- you log off, since sysload loads the driver as a child job of the
- HI rather than the CLI. You may use the sysload command in a
- submit file, such as r?logon or loadinfo.
-
- If a driver is already loaded and you reload it without resetting
- the system, a new instance of the driver is loaded.
-
- The loaded driver or job do not have access to standard :ci: and
- :co: since it is not associated with any user or terminal.
- Therefore, all input parameters must either be specified on the
- sysload command line or the driver must read them from a file.
- Likewise, any output messages must be directed to a log file.
-
- For further information on this command, refer to the
- Command Reference manual.
