Updating the Operating System
You should also retain a hard copy of your system’s current configuration. If you use the
CONFIG option with UPDATE, UPDATE replaces the configuration files in the group
CONFIG.SYS on disk with any that may exist in the CONFIG.SYS on the system load tape
(SLT). If you use this option, you can unintentionally replace your system's current
configuration files with the ones that UPDATE provides. In the event of an unintended
replacement, if you have a listing of your current configuration, you can easily regenerate
your system's current configuration.
Use SYSGEN to generate current configuration listings. For information on using
SYSGEN, refer to Chapter 4 , “Using the System Generator (SYSGEN).”
The above information has provided you with an overview of the update process. If you are
planning to update your system, please follow the instructions in the HP e3000 MPE/iX
System Software Maintenance Manual which came with the system tapes.
