How does one completely reboot a PC/XT/AT from software control? Before you say "... use interrupt hex 19 ...", please note that the BIOS bootstrap service accessed via interrupt hex 19 is not a complete reboot. It just loads the boot segment from drive A: and executes it. What I want is the reboot that occurs when one presses Ctl-Alt-Del (without using hard coded addresses which could be BIOS dependent). Anyone have any ideas? If I get a solution, I'll post it to the net. Thanks all in advance. --------------------+------------------------------------------------------- Graham Wilson | UUCP: uunet!mnetor!lsuc!
