Hoping someone can help me here. I need to disable ACPI on my laptop. It has the Insyde BIOS, rev 3.0. I've re-flashed the BIOS with the modded revision as in the modded thread (V1.45, 2.1 SLIC) but this has not worked. I presume the mod was to allow OEM installation of operating systems. I want to use the laptop as a DAW (Digital Audio Workstation). I'm currently getting undesirable DPC causing 5ms delay which is interfering with my soundcards audio streaming. The laptop is running Windows 7 Professional. I've already disabled unused devices and services in device manager, but there are several ACPI devices that cannot be turned of in Windows.
