Are you sure that it is not simply a bug in the program doing the POST? Look at the scitech source and you will see many BIOS quirks that have to be emulated in order for the post to work. If your post program is missing any of these the post won't work. So far every time I have encountered a non-working post it was fixed by tweaking some things in the post program. > -- > Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org > > -- Jon Smirl jonsmirl-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
