How would I create a delay that is 5 to 10 seconds long in assembly. An example would be really helpful.

The operating system I'm using is windows 2000, and the the architecture is for the x86 intel processor.
In Win32Asm? Or DOS16Asm?
Try looking up GetTickCount() for the former.
The GetTickCount function retrieves the number of milliseconds that have elapsed since Windows was started.
DWORD GetTickCount(VOID)
Parameters
This function has no parameters.
Return Value
If the function succeeds, the return value is the number of milliseconds that have elapsed since Windows was started.
Remarks
The GetTickCount function is identical to the GetCurrentTime function. Applications should use the GetTickCount function because its name matches more closely what the function does.
The GetTickCount and GetMessageTime functions return different times. GetMessageTime returns the Windows time when the given message was created, not the current Windows time.
The internal timer wraps around to zero if Windows is run continuously for approximately 49.7 days.
For DOS... there is also a TickCount but it's accessed by a location or via a BIOS int call, although the 'by location' method is preferred.

Delay for certain amount of time:
mov ah,86h
;CX
X = #of ¦Ìsecs to delay
int 15h
mov ah,86h
;CX
X = #of ¦Ìsecs to delayint 15h
That call also works but not on all BIOS versions... not on my really really *OLD* 286 computer for instance he he he.... Besides if it's seconds, you can just access the BIOS's clock which is 18.22065 (IIRC) clock ticks per second. If it's in milliseconds then that call is preferred, it's probably supported anyway.
