It's worth noting that attempting to re-POST many (most?) laptops will fail miserably - the code simply isn't available after boot. Saving/restoring state with VBE code tends to be more reliable, but there are some machines that need POSTing. In the long run, it's the sort of thing that needs a hardware database, which effectively requires it to be in userspace. -- Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
