EC

[This is preliminary documentation and subject to change.]

SUMMARY

This is the device driver for an ACPI-compliant embedded controller. It allows communication with this drive through device reads and writes, and implements an ACPI operation region for IO through ACPI control methods. Note that the driver does not support device removal. The sample runs on both x86 and Alpha platforms, and is 64-bit compliant.

BUILDING THE SAMPLE

Type build while in the \\Ntddk\Src\Wdm\Acpi\Ec subdirectory. A successful build creates Acpiec.sys.
