Windbg & rebooting

Several of you have complained about Windbg not reconnecting to the
target when the target is rebooted. We are looking into this.

We do know of 1 issue that may be the cause of much of your problems.

There are some versions of the Intel chipset that causes some
interference with proper COM port operation during reboot. Intel is
aware of the problem The work around is to disable Legacy USB support
in the BIOS. Legacy USB support is only needed if you have a USB
keyboard attached. My understanding is that newer chipsets from Intel
will contain the fix.

We would like more information about the status of this problem from
you. If disabling legacy USB and trying different COM speeds do not
work then please let us know.

Yep. That fixed it on both machines that I was having problems with
(machines with different bioses, but the motherboards must have the same
buggy chipset)! It allows the reboot with the debug and free kernels of
Win2k on both machines, so it looks like that’s definately a working fix.
You might want to post this to the microsoft.public.windbg newsgroup and
the ntdev list as well…

Thanks a ton for the help!!!

stressful…
