What do you mean by "entire System Information"?

The call (if such a wide ranging call were to exist) would have to be operating system specific.

Are your running linux?, windows 95, 98, Me, Nt,..., BSD, ... ?

GetSystemInfo(SYSTEM_INFO*)

GetSystemMetrics(int nIndex)

Have a look at MSDN for more detail.

What you're asking is very difficult.  You'd need a book on DOS that documents the BIOS services.  They would be able to give you much of this information.  There is no library (as far as I can remember) that you can call into in TurboC that would return all of this information.

Memory, however, was a black art under DOS, it would very much depend on what memory managers you had loaded and what version of DOS you are running.  Memory came in a few flavours: normal, upper, extended and expanded.  

I'm afraid my 'memory' just isn't that good and I'm not going to be able to help you with any of the details here.

Regards,
Mike.

Use a book called 'ADVANCED MS-DOS PROGRAMMING' BY RAY DUNCAN it gives u a list of all Documented as well as UNDOCUMENTED BIOS SERVICE ROUTINES which can be invoked using interrupts (i am talking about the int86 function) see help on int86 in TURBO C

I believe there IS AN INTERRUPT for getting 'BASIC' System information like BASE MEMORY and how many terminals type of Adapter and stuff...check out the book it is a complete reference if u still don't get the last resort is INTEL MANUALS if u can find one!!
