IMHO:
Steer clear of RH 7.3! I have heard of way too many people suffering from
multiple system problems with it. Mandrake is a very competent solution.

Subject: Re: [olug] ACPI Under Linux
Brian,
Thanks for the response. Here is the additional info I have, including
how my power management is set up in the BIOS along with what the
documentation says the /proc directories should be. As I said in the
original message I only have the /proc/acpi directory which the
documentation doesn't mention. Hopefully, someone locally has played
with ACPI. I'm thinking of going to Mandrake 9.0 and abandoning RH7.3,
but this Gigabyte GA-7VKML motherboard isn't listed under the compatible
motherboards. I forgot to mention in the original message that I had
already updated to the latest BIOS available from Gigabyte.
THANKS
