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.

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

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. -- Dave Levenson Internet: dave@westmark.com Westmark, Inc.
