Always did, or would have had there not been a OUT port bug in the original EMM386 reboot routine that was fixed. I don't know why it was originally set it up that way, but hard to believe it was done without a reason. But I'm seriously thinking about adding explicit warm boot flag into the Ctrl-Alt-Del handler, removing the OUT port reset there, and letting FFFF:0 real mode BIOS address handle things. I suppose it's possible the original coder thought things could be so munged up that the reset to real mode from protected mode might fail before FFFF:0 access and cause lockups, but that's not much different from other types of crashes which mess the PC's mind up so badly you have to hit the reset switch anyway. Can't think why else you'd want a POST to happen. ------------------------------------------------------- This SF.net email is sponsored by: The Robotic Monkeys at ThinkGeek For a limited time only, get FREE Ground shipping on all orders of $35 or more.
