how to change to uniprocessor HAL?
Compaq Presario S4020WM running Windows XP Home (SP1) with the latest
updates Device Manager, Computer says "ACPI Multiprocessor PC" (drivers hal.dll ntkrnlpa.exe ntoskrnl.exe) The AIDA32 v3.93 sysinfo tool under Operating System, Operating system suggests: "Only 1 CPU installed, you should change to uniprocessor HAL." HAL=Hardware Abstraction Layer ref: http://support.microsoft.com/?kbid=309283 I googled and the only way I can see to make this change is to reinstall the op system, but I know of no such options during installation! Attempting to update the drivers offers nothing new, and says the best drivers are already installed. Is my computer's performance less than optimum with the present setup (vs uniprocessor HAL)? If so, how? Suggestions? -E |

It should be ACPI Uniprocessor PC. Have you right clicked on the current
entry and select Scan for hardware changes? HH "Euclid" wrote in message link.net...

No, but I tried it...
It scans, then comes back as the same thing: ACPI Multiprocessor PC. All of the Microsoft literature suggests that the only way is to reinstall the op system. During that installation process, it is supposed to offer an option to press F6 to make some kind of setting/selection related to SCSI. At that point there are supposedly two "hidden" options, to press F5 or F7 (rather than F6). Pressing F5 supposedly offers the option to select ACPI Uniprocessor PC from a list. It has been a long time since I last installed this Compaq OEM WinXP Home op system, so I might not remember, but I don't remember any such option being offered. I'm still wondering if it is worth the effort. Is my computer's performance substandard because of this? What is the effect? -E "HH" wrote in message ... It should be ACPI Uniprocessor PC.

The only way to tell would be to run some processor benchmark tests. I use
Wintune for simple Dhrystone/Whetstone (Integer/FPU) testing, but it is no longer available online since Windows Mag went kaput. Try to find some testing software, then post your results. As for such an option when installing a Compaq OEM version of the OS, I doubt you would have it either. HH "Euclid" wrote in message link.net... No, but I tried it...

This machine doesn't have a HyperThreading CPU, does it? From XP's
perspective, that IS two CPUs. Tom "HH" wrote in message ... The only way to tell would be to run some processor benchmark tests.

No. It has an Athlon XP 2400+ processor.

Perhaps I'll look for that option when/if I reinstall this op system someday. -E |
