Default 162Bug Controller and Device Parameters
The 162Bug initializes the parameter tables for a default configuration of
controllers and devices (refer to Appendix B). If the system needs to be
configured differently than this default configuration (for example, to use
a 70MB Winchester drive where the default is a 40MB Winchester drive),
then these tables must be changed.
There are three ways to change the parameter tables:
1. Using the BO or BH commands. When you invoke one of these
commands, the configuration area of the disk is read and the
parameters corresponding to that device are rewritten according to
the parameter information contained in the configuration area. This
is a temporary change. If a cold-start reset occurs, then the default
parameter information is written back into the tables.
2. Using the IOT command. You can use this command to reconfigure
the parameter table manually for any controller and/or device that is
different from the default. This is also a temporary change and is
overwritten if a cold-start reset occurs.
3. Obtain the source. You can then change the configuration files and
rebuild the 162Bug so that it has different defaults. Changes made
to the defaults are permanent until changed again.
Disk I/O Error Codes
The 162Bug returns an error code if an attempted disk operation is
unsuccessful.
