Use Debug to determine VGA Adapter

[Hpro]

For expereinced computer users it is very easy to find out the manufacturer and model of the VGA adapter - but may even then sometimes one can run into troubles to find the exact match.

This here shall be a very easy step to do this using Debug which comes with Windows and can be accessed from within Windows or from the command prompt or DOS PROMPT - the outcome will always be the same

Open debug either from the Run command line (use Browse to locate it)or by typing DEBUG at the command prompt

YOu will see a flashing cursor there just type in the following code and then press enter - on the right side of the screen you will see all or most the info you are looking for - entering ..

Example
-D C000:0 and press enter will reveal the VGA adpater installed into the computer.
-d again will let you see more data - for some VGA adapters there it may be necessary to repeat this several times..

To quit DEBUG use Q and enter.

Using DEBUG

[Toaster]

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.
