SUMMARY

This kernel mode driver is the system supplied SMBus Smart Battery Subsystem Miniport driver. This driver serves as an example of both a battery miniclass driver, and as an example of a driver to access a SMBus device.

To build the driver, type build in the \\Ntddk\Src\Wdm\Acpi\Smbbatt directory. A successful build produces Smbbatt.sys. The necessary Inf file is battery.inf and is located in the %WINDIR%\inf directory.
