Disk Opt v1.0 ■ Copyright 1988 by Jack A. Orman
Correct usage is:
DISKOPT /Sx /Tx /Rx
/S=Steprate. X can equal 3, 6, 9, or 12
/T=Disk motor off-time. X can equal 15 to 25
/R=Refresh rate. X can equal 01 to 99
** D I S K O P T **
Diskopt allows you to set the steprate of the floppy
drives on your system. This can speed up you disk access
if the drive is capable of handling the faster steprate
(lower number = faster access). If the drive makes a
grinding or other abnormal noise, set the steprate to the
next higher selection. Only 3, 6, 9 or 12 are valid rates.
Diskopt can also set the delay time that is used to
determine how long the floppy drive motor continues to run
after the disk access is finished (Lower number = faster
access). You don't want to set this number so low that the
drive motor is starting and stopping excessively, but you
can cut down on unnecessary drive idling. Determine the
optimum value by setting the /T value to 22; then type
DIR. Watch the drive light to see if it stays lit
continuously or if it goes on and off. If it stays on,
select the next lower value. Continue this process until
the drive light begins to flicker on and off. The next
higher number for /T is correct for your system.
Refresh rates: CAUTION! This is a setting that can cause
loss of data if it is set too HIGH. Tandy 1000 users should
be especially careful when playing with this setting. It
can be used to increase the actual processing speed of
your computer by increasing the time between refreshes of
the RAM. This allows the CPU to do more productive work
instead of refreshing those dynamic ram chips so often.
Use a program such as CPUMHZ.com to test the speed of your
system and then vary the refresh rate (start low and work
up). Apparent speed increases can be achieved in this
manner. If you set the time between ram refreshes to a
value that is too high, the capacitors that are the memory
cells in the ram will lose their charge (and consequently
the data bytes).
W A R N I N G: Use this program at your own risk! The
drive will probably not be damaged by any setting of
steprate or drive-off time but be cautious. If the drive
sounds like it's struggling, it probably is. So back off
on the steprate.
W A R N I N G !!! W A R N I N G
Messing with the refresh rate will cause data loss if you
set it too high! However, rebooting will cause all of the
setting to return to normal. Don't be afraid to play
around with the refresh rate to get better speed, but
don't use the refresh option until you are SURE that data
bits are not being lost. I will NOT be responsible for any
data loss, drive damage or other malfunctions resulting
from use of this program. USER BEWARE!
