Hoover" Sender: owner-freebsd-mobile@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org It seems that on Win98 compatible APM BIOSes, you need to have interrupts enabled. I have the 3.0 CD-ROM and am studying the code to figure out where to do the cutting. I'd make up a patch set for 2.2.6 (haven't upgraded the mother computer to 2.2.7 or above yet), but I installed PAO and I haven't taken the hour to sit down and figure out exactly where to apply the scissors.
