Fields

ulBankLength    Length of the bank.
                Represents the combined length of all parameter packet fields. 
                This is a required field for all calls, including those made by
                way of the 32-bit DosDevIOCtl, with a minimum packet length of  
                10 bytes.

usBank          Current bank.
                The current bank value to be set/returned. The bank size is
                64KB regardless of the value specified for the video mode type
                field.

usVideoModeType Current video mode type. 
                Defines the adapter video mode type to the device driver, and 
                has one of the following values:
