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. -- Dave "Gizmo" Gymer dgymer AT gdcarc DOT co DOT uk http://www.mal.com/~dgymer/ -- Never attribute to malice that which can be adequately -- explained by stupidity.
