Does FreeBSD permit > irq sharing ? Provided that your hardware (properly) supports IRQ sharing, then FreeBSD will support it without problems. If you start to notice problems (crashes, problems using devices, FreeBSD not detecting certain devices) then it's time to go into your BIOS and fiddle with the features that control IRQ sharing and PnP operation there. -- Matt Emmerton GSI Computer Services To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
