[A83] Re: Problems with Virtual TI [OT]




Ok, since no one else is giving a decent explanation, here it is:

The SysReq key was brought in under the 286 for a System Request.  What it 
does it move the machine from being a normal 16-bit machine with a memory 
cap of 640K to a Protected Mode machine with access to more the 1Mb of 
memory capability.  Different OS's use it for different things now, such as 
switching to a 'fix' mode.  On many keyboards, it has become a CTRL 
function of the printscreen key, as screenshoting is more important to some 
people than keeping their machine up without restarting.  The SysReq key 
has become like Scroll Lock and Pause: Only people who really know what 
they are doing use them.  Pause, for example, can help debug your startup 
under DOS or Windows by stopping the load sequence until you press Enter.
