1. I didn't find a good sentence about how you installed motherboard drivers. It appears you let Windows do that. Stuttering would be normal since the IDE drivers are going to be quite slow.
2. Read http://winhlp.com/node/10
Firstly, I can afford to play around; I've had XP on ide1 since Fall 2001. I've left it at SP1 stage, and everything -- including sound -- works fine.
Recently, I bought a used 40GB ATA100 drive and attached it to the HPT370 UDMA/ATA controller on my 440BX motherboard. Then, I installed a fresh copy of Windows XP Home and SP2 (I wanted to use PivotPro with my new LCD monitor and it seems to need SP2).
And here's my problem -- severe sound stuttering on internet radio (possible all sources of sound but I haven't checked them out).
Windows XP installed itself as ACPI; doubtless, it is supremely confident it can handle any interrupt challenges it faces. HA!
Windows has assigned IRQ9 to my 3COM ethernet card, my Soundblaster Live card, and the HPT370 controller. All my devices are old (6-9 years) and no longer supported; in fact I think the most recent drivers are all pre-SP2. I've upgraded the drivers as much as possible. Moving the cards has had no effect on the problem or on Windows' IRQ assignments. And selecting IRQs in the BIOS can't help; Windows overrides BIOS IRQ selections when in ACPI mode. I can't think of any other solution except manually assigning IRQs.
But to do that, I have to update the "Computer" drivers from ACPI to Standard PC. I'm assuming I can use the Hardware Update Wizard and select the driver, manually.
My questions ---
1. Should I get the HAL.DLL from the original Windows XP CD or should I get it out of the SP2 cabs?
2. Do I have to install a new ntkrnalpa.exe and a new ntoskrnl.exe, also? If so, where do I get them?
3. Is it possible to switch back to ACPI without reinstalling Windows?
4. Will Windows boot after I've done this?
5. Has anyone here done this? Had success?
I know I'll lose ACPI power and shutdown benefits and it may not work anyway, but given the restraints my system is working under, has anyone got a better idea of how to solve the "stuttering sound" problem?
Any help will be most appreciated.
