Using IntControl(32...) to Return Memory Address

Keywords:    IntControl(32,,,,)	  IntControl (32,,,,)

Question:

Could you provide any examples of the IntControl(32,,,,) command? What are the limitations to its use on NT?

We would like to determine BIOS information on our systems for Y2000 purposes. Is it possible for the IntControl(32,,,,) to return the value at address F000:E061 for example, similar to the way MSD can? Or is this not what the function is intended for.

Answer:

IntControl32. Assuming somehow that you have managed to get an address of some memory location that you wish to inspect, IntControl 32 would let you read it.

It is limited to memory areas that the script has read access to.

It's usage is very rare, and was used to refer to data pointed to in a structure in a BinaryBuffer returned as a result of a DLLCALL operation.

Unless you have a very specifiec need, I would avoid it like the plague.

On the BIOS information question, check my math....

	F000= 15 * 65536
	E061 = (14 * 4096) + (0 * 256) + (6 * 16) + 1

	address=F000+E061

	value=IntControl(32,address,"BYTE",0,0)

	Message("Byte Value at %address% is",value)
