I'm pretty sure about this. If would be very complicated for HPFS.IFS to
know that there is a call the chkdsk elsewhere in config.sys. If the
autocheck option calls out drive D: it is going to get chkdsk'd via the
IFS.

If I understood your description of your config.sys, you have:

IFS=C:\OS2\HPFS.IFS ... /AUTOCHECK:CD
DEVICE=C:\OS2BOOT\CHKDSK.SYS
CALL=C:\OS2\CHKDSK.COM D: /C

The way this works is nothing gets chkdsk'd unless there is a dirty
shutdown. If there is a dirty shutdown, the autocheck invokes chkdsk for
C: and D: and then forces a reboot. The call the chkdsk.com never gets
executed. After the reboot, the autocheck does nothing because the drives
are not dirty. The chkdsk.com runs but bypasses the chkdsk logic because
it was invoked with the /C option and the drive is not dirty.

What should work, and should save a reboot is:

IFS=C:\OS2\HPFS.IFS ... /AUTOCHECK:C
CALL=C:\OS2\CHKDSK.COM D: /C

The caveat is that everything called for by config.sys, directly and
indirectly, must come from the C: drive until after the call to
chkdsk.com. In some setups, this might not be possible, so the chkdsk.sys
method is the only viable alternative.

As I said, I have not tested this, but I would be surprised if were
otherwise.
