Why complicate an interface just to make an already slow processor go unnoticeably faster? -Matt :>> On the 386 and 486, call gates are faster.

(Plus an additional parameter to completely disable the :multiplexer interrupt, as this should *not* be done until you've rebuilt :everything to use the call gate interface instead ;) : :--- :Marius Bendiksen, IT-Trainee, ScanCall AS : :To Unsubscribe: send mail to majordomo@FreeBSD.org :with "unsubscribe freebsd-hackers" in the body of the message : Matthew Dillon Engineering, HiWay Technologies, Inc. & BEST Internet Communications & God knows what else.
