Hi Jonathan,

I like this! Nevertheless I have a good reason to use it (there may be a
better way, but it worked fine for me).

I run a BBS that I want to power-off once a day to force a cold start, and
at a time that everybody (at least me) are supposed to sleep. I do this
just in case something peculiar happened during a holiday period (which may
help only in some cases!).

Just before system power-off by an external time-operated switch all
sessions finish (by themselves), apart from one. This session waits a
little and then issues a SETBOOT command specifying an existing but
non-bootable drive (/IBD:d). This prevents a reboot of OS/2, so my HPFS
volumes won't be CHKDSKed at next power-on. A nice 'feature' of SETBOOT: it
does not change the default boot-up partition. So with power-on a normal
boot follows.

Cheers, Rob
