First, I should warn you that this reply is of very technical nature, so don't try to answer unless you have a good idea of it.

Could you elaborate a little why having separate IRQ's for different devices should get better performance? I'm not really familiar with how IRQ's work on the x86-architecture on a low-level technical level.

Every IRQ has a separate interrupt-handler right? (Seperate adress in memory to jump to)

And with ACPI most devices are supposed to use the same interrupthandler. (On my system it sets all pci-cards IRQ's to 7, but leaves most system-devices on different IRQ's)

So if I got this correctly the interrupthandler has to decide from which device the interrupt came from if the IRQ is shared. That shouldn't be such a big deal should it? And it shouldn't affect PCI performance as the interrupthandler is handled by the CPU. And since the CPU is quite a lot faster than the PCI bus these days, the added time it takes until the CPU has send a receipt back to the interrupthandlingchip wouldn't be noticable one could think.

All this is just speculation, but I wan't some evidence before i turn off ACPI, and not just trust what cremware claimed in their beta 2.04 w2k drivers. Turning the computer off manually is such a bummer methinks and that doesn't work without ACPI.

Nice list of tips, by the way.

Well it's a good start but missing a few important details... and with XP you don't really need the .ini tweaks you mention. I think XP is better than 2000 for audio, but if you're a Logic user, it's probably a good idea to keep 9x around until 5.0 is released.

BTW I will put my old guides up once I have completed more detailed versions with pictures for my users.

yeah yeah! gimme gimme. I was wondering why you put those links down..

Before I even started tweaking XP, I spent lots of time getting my backup routines right.. I've had a IBM HD crash on me once, and I'm never going to let it happen again. Sometimes it's the basics that count.. BACKUP FOR A BACKUP!!

Make a drive image of a clean OS. Install audio apps, do tweaks, and make another image.
Put all your work on another physical disk and make double backups of those! Don't let data loss ruin your work if music is what you sell!
100GB HDs aren't around just to be filled up with mp3s and whatnots. Use them as removable backup media!

Well... I guess this is a little extreme.

But it is mission critical at times.

I have just replied to another thread regarding this.
Please do not take site content without permission.
A link to http://www.bluelifeaudio.com would be the way to go...

Please have a bit of respect for the work we are all putting into it.

Here's a few from my guides... (the basic text will reappear for PlanetZ users once I have completed the "enhanced" version with pictures.)

You do not need ACPI, APM will do

Btw, I went for the test: installed "ACPI Multiprocessor PC" instead of "Standard PC".
Had to reïnstall Win2k: 'overwrite all newer files?' -> yes and so then I had to get all ServicePacks again. Updated Intel HD and other drivers again cos they were overwritten during Repair Install Win2k. First time I did not choose to overwrite, and I had to do the Win2k setup again.

Finally got ACPI Multiprocessor installed, Pulsar still often gives CopyProtectionViolation Errors, and then it won't load the DSP's/project.
Just takes some extra time for second attempt.

Yep, Atomic is right... APM can provide the functionality for switching off the computer automatically. I personally have left it off... I've been switching my computer off manually for the last 2 or 3 weeks, I really can't understand why people would rather have an unstable system than do this ?!?

Yes, an unstable PC.. I've spoken to countless people now, who have had major problems with ACPI, which have miraculously disappeared when they REINSTALLED with Standard PC (not just a change of driver on the same installation).

peace

Full format and reinstall or would a reinstall over the old installation do?

If you over-install (I choose to overwrite all newer files with the original ones when I changed ACPI to non-ACPI), make sure you go back to WinUpdate and get all the updates again. WinUpdate will tell you already have them installed *BUT* they are overwritten during the over-install. I hope uninstall of the all the updates is not be needed!
As you'll see, ie. Outlook Express won't load anymore after reïnstall. After updating again Win2k, all worked normally.
