CONFIG80 works in much the same way as CONFIGUR. It is used for specifying the type of drive
located at each physical drive address on the H-17 controller. The parameters which may be
entered are:
Track Density - May be either 48 for 40 track drives, or 96 for 80 track drives. Note that
only the first digit needs to be entered (either 4 or 9).
Number of Sides - May be either "1" for single sided drives, or "2" for double sided drives.
Step Rate - May be any value from 4 mSec to 40 ms in increments of 2 ms. Enter a
carriage return after inputting the step rate.
Once all desired changes are entered, enter either "X", "Y", or "Z" to write the new BIOS back to
the disk and re-enter CP/M. The "X", "Y", and "Z" commands work in exactly the same way as
under CONFIGUR.
XDIR is a utility which provides a greatly enhanced disk directory display. It uses the same
command syntax as the standard CP/M DIR command, except that it also allows viewing $SYS files
by giving a file specification followed by the letter "S". It will display all files on a disk, sorted in
alphabetical order, with the size in Kbytes of each file, as well as a count of the number of
files on the disk, number of directory entries used, number of directory entries left, total disk size
in Kbytes, total space occupied by files, and total remaining space. XDIR is run with a command
line of the same format as the standard CP/M D -IR command:
XDIR *.COM will give a listing of all COM files with the $DIR attribute.
XDIR *.COM S will give a listing of all COM files whether flagged as $DIR or $SYS.
XDIR will give a display of ALL files on the currently selected drive.
XDIR C: will give a display of ALL files on drive C:.
XDIR B:*.COM will give a display of all COM files on drive B:.
XDIR E: A*.* will give a display of all files on drive E: with names which start with "A".
FBAD is a non-destructive disk test and bad sector lockout program. FBAD can be run on ANY disk,
at ANY time. It WILL NOT alter ANY data or files on the disk. FBAD reads the ENTIRE disk, including
system and directory areas, to locate any unreadable sectors. If a bad sector is found, the
following actions will be taken:
