Poll: ACPI in Windows 2000?

I'm trying to gauge the preferred "Computer Type" here for those of you using Windows 2000. Mainly because I'll be re-installing Win2K soon and I'm wondering if it'd be possible to set up a stable ACPI system that runs just as good as my present non-ACPI setup.
 
I am getting the IRQL not less or equal BSOD under ACPI with my webcam. I didn't excatly reinstall using standard PC but I just changed the HAL driver. Seemed to work fine now. Although I have since reinstalled my system using standard PC.
 
ACPI works great. Funny thing, in the MSI BIOS last time I checked they spelled it "IPCA function"

hehe 🙂
 
I dont like it. It's a good idea, but so far it hasn't done anything for me. I've had much fewer problems since I got away from it.



 
I have heard rumors of increased performance when turning acpi off (or running a non-acpi system) compared with acpi. Does anybody know of some benchmarks to back up this claim? I would rather not mess with my perfectly 100% stable system messing around with it, only to find that there is no difference in speed.
 
I tried it with ACPI HAL and had some flakey problems so I did re-install to convert to Standard PC HAL. I like Standard better but that just my opinion and it may not work for everyone.
 
I've used both Standard PC and ACPI HAL with my Asus CUV4X PIII 960 and it works fabulous. Suspend-to-RAM is kickass. I'm using all the finicky hardware that supposedly doesn't work good under ACPI (namely the SBLive and ATI AIW Radeon). Everything works, perfectly. Not one BSOD! No performance drop either.
 
I was contemplating trying out ACPI HAL because I'd be re-installing Win2K soon anyways, and I noticed I have this one app which needs the ACPI HAL to operate. I use "ShutDown Now" to automate remote shutdowns of my machine for a number of reasons but without the ACPI HAL all it does is make Win2K go to a screen that says "It is now safe to turn off your computer". A bit silly since choosing Shutdown from the Shutdown menu causes it to completely power-off. Well, Suspend-to-Ram sounds nifty so when I get around to reinstalling Win2K I'll try the ACPI HAL and see how it goes.

Thanks for all the responses.
 
Don't worry about it, you can switch contrary to what Microsoft recommends. If one doesn't work just change the system type, there's no need for reinstall.
 
potz- I don't think that is such a good idea. This is from the MS knowledge database and concerns switching without doing a re-install to accomplish it:

WARNING: Note that you should not attempt to change from an ACPI HAL to a standard HAL or from a standard HAL to a ACPI HAL under any circumstances. Doing so will result in your computer not starting properly or at all. This occurs because the Plug and Play device tree that would be currently loaded is for ACPI, and it does not get reconstructed or revert to a standard HAL Plug and Play device tree. Because of this (the device tree structures being drastically different), the system is unaware of any hardware changes after the computer restarts to include the location of the boot device. Microsoft does not recommend or support this procedure as it will result in data loss.

Sounds scary enough to me. This can be found here under Setup and Top Issues.
 
Thanks for the note, Shark.

What I figure I'll probably do is run a comprehensive group of benchmarks before and after to ensure that performance of all aspects of the computer does not deteriorate, including gaming performance and sound performance (the only 2 risk factors I've heard - I don't think ACPI affects CPU or HD/Memory performance).
 
I actually just switched over to Standard PC today, since I was a tad uncomfortable having my Radeon, SBLive, On-board RAID chip and NIC all on IRQ 11. The changeover went smoothly - Win2k recognized my hardware over again almost without a hitch (the RAID controller took a few minutes to get set up properly). Things seem to be going well now, although the switch didn't actualy fix my problem - this machine still freezes up for a few seconds every once and awhile.
 
Ever since I found out about the F5 & F7 trick during install, I haven't been using ACPI. Every once in a while, I'd get some intermittent freezing problems. Disabling ACPI has fixed this, but there is no performance difference as far as my machine goes.
 
I occasionally get freezing problems now and again and right now ACPI is *NOT* installed. I do have a Live! and a VIA chipset mobo, though. Getting a TB Santa Cruz soon though, I'll see if that has any effect before re-installing my system with ACPI enabled. I hope SC supports ACPI.
