On looking at this mailing list i found the site http://acpi.sourceforge.net which appears to show that my problems are to do with something called the DSDT. The site has a fix for my motherboard but in order to use it i would have to recompile my kernel, i think, which isn't something ive ever done before so i wouldn't really be comfortable doing it. On further reading it appears someone has written a patch to enable people to change there DSDT without recompiling there kernel everything ( http://gaugusch.at/kernel.shtml ) which has been included with some distro's of linux. Does anyone know if there is a change of having this included with fedora? or if its already included and i dont know about it? thanks Simon -----Original Message----- From: fedora-list-admin@xxxxxxxxxx [mailto:fedora-list-admin@xxxxxxxxxx] On Behalf Of Dave Jones Sent: 20 December 2003 19:30 To: fedora-list@xxxxxxxxxx Subject: Re: ACPI disabled because your bios is from 00 and too old On Sat, 2003-12-20 at 18:35, Simon Bell wrote: > Ive recently installed fedora core 1 onto an old desktop machine.

Like all heuristics, sometimes it makes the wrong decision. It doesn't actually know if its bad, but it does trap an awful lot of bios's that are bad from that era. If you know for a fact that it works ok with acpi=force, filing a bugzilla report with dmidecode info means we can whitelist it for future kernels. You may also want to run the same question by acpi-devel@xxxxxxxxxxxx to make sure no-one there knows of something bad in these systems.
