ABOUT ACPI and PCI LATENCY

france666reds · Mar 20, 2003, 06:52 AM

I'm newbie not only in KX Drivers forum but also in tuning my system correctly.

Kx works well if ACPI is disabled and if PCI latency in Bios is modified.

I can't understand these terms.
What do You mean with ACPI, may I verify if I have ACPI Disabled or not?
HOW DISABLING?

And About PCI Latency - Is it important? Why? and then how to modify?

Configuration:

XP Home sp1
P IV 1,6 ghz
Audigy 1 platinum
Cubase 5.1.r1
Sonar 2.2 XL
etc
256 mb RAM

Hello,

It's easy to check if ACPI is enabled - go to Control Panel and System and open up the Device Manager from there, and right at the top you should see 'ACPI PC' if it is in ACPI mode or 'Standard PC' if not (or something similar).

It's also (in theory) easy to change it from here. However, it may have some unwanted side effects - unfortunately the best thing to do is to install XP clean as a Standard PC and not an ACPI one.

PCI latency, you -shouldn't- have to worry about, people correct me if I'm wrong - ACPI is the big baddie under XP.

Just in case anyone's wondering, you press F5 at the very beginning of installation when it says 'press F6 now toinstall RAID drivers' (...or something...)
