ACPI Problems

[Guest]

I just built a new computer based on an Athlon 64 3000+ processor, ABIT AN8
Ultra motherboard and Windows XP Pro operating system. All the other
components are also new and represent current technologies, however Windows
indentifies my computer as a "Standard PC" which is a non-ACPI HAL. I think
my equipment should support an ACPI HAL, but need help in learning how to
determine if it truly is compliant.

If it can support ACPI HAL, I believe I have to reinstall Windows and I need
to know how to make sure the correct HAL will be installed if I go through
this process.

Thanks for the help!

I read that document but wasn't able to figure out from it what equipment or
software determines if the machine meets the requirements of ACPI. I tried
to search for the txtsetup.sif file but couldn't find it. I'm also not sure
if I can look at the 10 tables that are built by BIOS to see what information
they have in them. Can you help with either of these?

One issue that came to mind in looking at the document is that since I built
the computer myself, that might create create problems in the creation of
certain tables because the example shows OEM ID = "Compaq" and I'm not sure
how this would get filled out properly when it is just an individual
constructing the machine.

You got just about all I know about it. What's your BIOS date?

[[Microsoft says some BIOSs--particularly those created before January 1,
2000--may not be able to take full advantage of Windows XP's hibernation and
power management features.]]

Start | Run | Type: regedit | Click OK |
Navigate to ...
HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System
Value Name: SystemBiosDate
Data Type: REG_MULTI_SZ
Value Data: This should show the BIOS date.

Make sure you have the latest bios for your motherboard.
Make sure you have enabled ACPI in your bios (while you are at it, you might
as well enable APIC if it is an option).

Once you've done this, Windows setup should install the proper HAL

I assume that ACPI is already enabled in BIOS, because while there is no
specific option to enable or disable it, in the power management screen of my
BIOS it does list the following:

ACPI Suspend Type

and this is set to S3 (suspend to RAM). I couldn't find any option for
enabling APIC. How can I tell if it is enabled?
