ACPISIM

[This is preliminary documentation and subject to change.]

SUMMARY

This is a 3^rd party ACPI Operation Region provider driver sample. This sample is compatible with both 32bit and 64bit platforms.

BUILDING THE SAMPLE

The sample is build with the standard DDK BUILD utility in the standard checked or free DDK build environment. Simply type build from the \\ntddk\src\wdm\acpi\acpisim\driver directory. A successful build produces ACPISIM.SYS.

An installation file, ACPISIM.INF is provided in the \\ntddk\src\wdm\acpi\acpisim\inf directory. Sample ASL required to enumerate the 3^rd party operation region device is included in the \\ntddk\src\wdm\acpi\acpisim\asl directory. Install ACPISIM.SYS by compiling a BIOS containing a device with the PnP ID of ‘ASIM0000’, and install the driver using the INF when Windows enumerates the virtual device.
