DC FLIGHT v1.0

FREEWARE Program

You are free to distribute this program, just so long as you keep the
operating instructions enclosed and intact.
--------------------------------------------------------------------------
Operation
---------
DC FLIGHT installs a routine into the read/write vector (RWABS) of storage
devices- floppy disks, hard drives, ramdisks, etc. Each time such a device
(all with the exception of the floppy) is accessed, the floppy drive A light
will come on until the operation is finished.
Now you can monitor the usage of ramdisks and caches, since, generally, there
was no way to know when they were active.
NOTE: Some ramdisk and cache operations may be too quick for you to notice
the floppy light.
Also, this is a great substitue for hard disks which may not have a working
"busy" light or at least not in plain sight.
Installation
------------
From the:
1) Desktop
Run DCFLIGHT.PRG from the desktop.
An info alert prompts you to [Install] or [Exit] DC FLIGHT.
Install places DC FLIGHT into the device chain (see above) and
stays resident.
Exit(ing) terminates the program with no installation.
2) AUTO folder
Copy DCFLIGHT.PRG to your AUTO folder. (Best if last. See below.)
Upon execution, program information is printed to the screen.
DC FLIGHT is placed into the device chain (see above) and stays
resident using only 392 bytes of memory.
NOTE: You will want DC FLIGHT to install itself after all storage devices
have been installed, so that DC FLIGHT will be able to show accesses
throughout the vector chain.
Hard disks normally are setup to AUTOboot, so that is taken care of.
Any other devices that have drivers in the AUTO folder, should be placed
before DC FLIGHT.
If they are an accessory, then that is another story...
