The IOCC_CONFIGURATION CommandCode consists of all the CommandModifiers responsible for returning information about the characteristics of the devices supported by the driver, as follows:
IOCM_COMPLETE_INIT
Indicates that the driver can complete its initialization phase.
In the interval between driver initialization and receipt of this IORB, the device driver must not disable its INT 13h BIOS support because this support is needed to load other components of the operating system.
IOCM_GET_DEVICE_TABLE
Returns the DEVICETABLE structure in the buffer supplied by the caller. DEVICETABLE contains detailed information on each adapter and the associated units supported by the adapter device driver.
Remarks
Support:
Note: Any adapter device driver that registers by way of the RegisterDeviceClass DevHlp must process this IORB and return a valid DEVICETABLE, even if the driver supports 0 adapters.
