Sysreq key

My DELL Inspiron 1100 has a Blue labeled  "Sysreq"  under the  "Delete" key.
When I press  "Fn" as is also Blue + "Sysreq"  the Display just flickers.
Does the "Sysreq" have any fuction.?

Hey Gary, A Google search on just the word turned up this information.

If this is what it is, I suggest you update your virus scan and run a complete check, and the same with your spyware sofware.  Let us know how it goes, and good luck.

Like I said its a Key label on my Laptop Keyboard, not a Virus.

I found the below info , so perhaps its leftover from previous versions of Windows using DOS.?

"Other odd keys worthy of note on your keyboard include the SysRq key (sometimes appearing as SysReq), which shares the same key as the ?Print Screen? key. (Historical sidelight ? SysRq was the ?84th key? added when the 83-key PC/XT keyboard became the 84-key AT keyboard.) Unless programmed by a particular application, the SysRq key does nothing in most operating systems, including DOS, Windows, and OS/2. "

Just thought I might be able to be programed using XP.

Ah, memories! As explained in  this article, the SysRq key was added by IBM when they designed the AT. The key was intended for use by multitasking operating systems as a means of getting the system's attention. Microsoft OSs never used it, so the key just sort of languished.

I wrote a multitasker a loooong time ago that used the key. The multitasker ran from MS-DOS, and when that key was pressed, the multitasker cleaned things up and returned control to the MS-DOS command interpreter, "command.com". Apparently some versions of Linux use it for similar purposes.
