Hi folks,
Debug is a great little program that has saved my butt a number of times.
However, I advise those NOT to just start punching in addresses to see what happens.
With debug in inexperienced hands, one can do the following:
Force a format.
Trash a file allocation table.
Write data to a system register that was not ment to accept data.
Reprogram I/O devices.
Force a cache flush.
Force a cache retrain.
Dump the contents of any register over existing data.
Corrupt data. (actually pretty easy!)
Force a system reset.
Force a cold boot.
Force a warm boot.
In the example given with the VGA adaptor, an address was entered and was requested to be displayed. With a minor modification of the command, one could "pop" or "push" an address.
Use care folks, its like experimenting with the format command.
