6. LIST/MODIFY DRIVE PARAMETERS
This option
allows you to examine and/or change the:
A. The Spared Track Table
This table specifies physical track numbers which are
to be skipped over when the controller accesses data on
the drive. This
allows one to hide the existence of media
defects from the
external user (the data service will look
perfect to him).
B. The Sector Interleaving Spec
The defaults used here have been optimized for small
computers like Apple II's. Typically, we have selected a
value of:
9 for
10 and 20 MB drives
12 for 6 MB drives
C. The Virtual Drive Offset Table
This table allows one drive to behave as if it were several
smaller
drives daisy-chained together. The table entries
specify the track number at which these
virtual drives start.
Normally, one would not have occasion to disturb these
parameters
unless the drive has been re-formatted or a bad
track
develops.
7. LIST/MODIFY CONSTELLATION PARAMETERS
This option
allows one to examine and/or modify the:
A. Master Multiplexer Connection Table
(Le.-specify what is connected to it) This table is usually
set to assume all the slots have a mux on them.
B. Constellation Polling Constants
These numbers determine certain aspects
of the Con-
stellation polling environment.
