Hi.

Does someone know if and how it is possible to access the contents of
the BIOS of a PC'386 via C program under UNIX (Interactive UNIX and
SCO UNIX)?

I would like to get a few informations out of the BIOS, e.g. the version
number, to calculate a checksum. The idea is to make a software package 
executable only on one PC.

Any solutions?
Any C programs ?
Any other solutions to protect software from running on several PC's?

Thanks.
           Peter.

	This article was crossposted to unix-pc.general.  That group is
not for discussion of IBM-type PCs running unix.  It is for discussion
of a 68010 machine known as the AT&T unix-pc, also the 7300 and the 3B1.
It runs system V unix. Please do not discuss IBM PC/unix issues in this
group.

		Thanks for your attention.	Jeff

I not trying to get anyone PO'ed, but once again a cross-post was mis-directed.
If Peter is a new poster then I'll simply explain that the unix-pc heirarchy is
ONLY for the AT&T UnixPC/7300/3B1.  If Peter is not so new, then shame on you
Peter!  Please, if and when you follow up to this article, don't cross-post to
the unix-pc newsgroup.  Thank you.

I haven't tried this, but I would expect that you could look at the
special file /dev/mem arount location 0xf0000 or so.  The program
which does this needs to be executed by root, or be set-uid root.
