Subject:	OpenDOS Ctrl-Alt-Del confusing IDE controller
Reply-To:	dgymer AT gdcarc DOT co DOT uk

After I finally got round to installing OpenDOS last night (multi-boots 
into either OpenDOS or MS-DOS 7 using the NT boot loader - and I don't 
even have NT!) I discovered that OD does some rather odd things to my 
second IDE controller when I use Ctrl-Alt-Del to reboot from OpenDOS.

The machine I'm using is a P200 with twin PCI IDE controllers on the 
motherboard; the hard disk is the master on the first controller, and 
my CD-ROM (a Creative Labs CD820E ATAPI drive) is plugged into the 
second. (There's also an IDE interface on my SB16, but it's unused.)
Under DOS 7/Win 95 everything's fine, but under OpenDOS, using 
Ctrl-Alt-Del to reboot causes the IDE controllers to get confused, and 
stops the CD-ROM from being detected. (Interestingly, the hard disk 
busy light also stays on, although the hard disk works fine; this light 
does NOT normally come on when the CD-ROM is busy.) Rebooting with 
either the reset button or the 4DOS "reboot" command works fine.

BTW, the CD drive works fine under OpenDOS even without the OpenDOS 
security installed.
