Hi All,

I have played with my win xp installation. I have changed my computer type to Standard Computer. I cannot revert to ACPI compliant machine.

Is it possible to change back to it? Or have I to reinstall Win XP?

Thanks in advance for any solution.

Sorry, but a reinstall is at hand; note point 3 in the article below:
"3. Device Manager does not permit the change from a Non-ACPI HAL to an ACPI HAL. You must use a new install of Windows XP or Windows Server 2003 for this type of change. Change from an ACPI HAL to a Non-ACPI HAL only for troubleshooting purposes. "
