I have been running an ASUS TX97-X with the 1001.003 ACPI beta bios for more
than 4 years now. My system was Windows 98 SE, and I have had no problems
with it. ACPI worked well and stable.

But I have now upgraded the system to XP Pro and I cannot get XP to pass the
ACPI test during installation of the OS. It halts with Stop: 0x000000A5
(0x00000002 .....) when i force it to install ACPI. This is because the
board is not ACPI compliant with respect to XP, but the ASUS manual states
ACPI compliance with future operative systems and I thik it is strange that
Windows 98SE can controll all the neccesary ACPI features while XP can't!

It is not important to me to use ACPI or APM. The one and only important
issue is to get information from you that enables a STR (Suspend To Ram)
after a given periode of inactvity in Windows XP Pro (SP2).

All the TX97-X bios's (ACPI or APM) are capable of doing this if You boot it
in DOS, but even if I try not use any kind of AMP/ACPI features in WinXP,
the OS still prevents the bios from entering suspend mode. I guess this has
to do with the installed "Standard PC" hardware abstraction layer (HAL)
still trying to take controll over the BIOS.

Does anybody know a cure or a fix for this?

ASUS TX-97-X rev 2.3
AMD K6-III/400MHz
ACPI BIOS 1001.003 beta
256MB RAM
160GB HD
ASUS V3800 TNT2 16MB

Oh c'mon, you didn't really believe that, did you? AFAIK even manual
writers are not in possession of magic crystal balls.

It is probably not completely without reason that said ACPI beta BIOS is
no longer available. Old ACPI BIOSes tended to have incomplete and/or
buggy ACPI support. NT 5.x generally has a much more complete (and most
certainly: rather different) ACPI implementation than Win9x.

Suspend to RAM (S3) is an ACPI feature that first appeared on late
i440BX boards. If you would be content with ordinary standby, however...

What did you expect from a Real Operating System[tm]? NT5 is not DOS
after all and hardly uses BIOS functions at all.

You'll need to install or enable the legacy APM device in XP.
Instructions on how to do this can be found on the web. Then at least
you should be able to enable automatic standby in XP's power options.
(I've never had to do it myself, since APM cannot be used on
multi-processor machines.)
