I located a file for upgrading the BIOS for my Compaq
machine but it requires Windows to install it. I
deleted the Windows that came with the machine several
months ago, so, for now, that option is out.
I created a file with the following commands:
sysctl hw.acpi.thermal.user_override=1
sysctl h
A few weeks ago, I upgraded my Compaq Presario desktop
machine from FreeBSD 6.2 to 6.3. I soon noticed this
message on the screen. Apparently, the system is
measuring the temperature of absolute zero.
At first, I thought it to be an installation error on
my part, but reformatting the hard drive
I have a Compaq Presario SR2180NX, which uses a P5LP-LE motherboard.
When I bought the machine second hand three years ago, I originally installed
and ran FreeBSD 5.5 without the error message. I recall that it began
appearing after I installed and ran 6.3, though I don't think it did under 6.2
