//  The video PROM contains the following structure starting at offset zero
//  from the PROM base address. Each entry is 8 bytes wide with the low byte
//  containing data and the upper 7 bytes reserved.
//
//      63               8 7                  0   Offset
//      +------------------+ +------------------+

//
//      Board_Identifier - supplies two bytes identifying the video board.
//
//      PROM_Stride - supplies the stride of the PROM in bytes.  Possible
//                  values are:
//
//                      1 - data every byte
//                      2 - data every 2 bytes
//                      4 - data every 4 bytes
//                      8 - data every 8 bytes
//
//      PROM_Width - supplies the width of the PROM in bytes.  Possible values
//                 are:
//
//                      1 - 1 byte wide
//                      2 - 2 bytes wide
//                      4 - 4 bytes wide
//                      8 - 8 bytes wide
//
//      PROM_Size - supplies the size of the PROM in 4 KByte pages.
//
//      Test_Bytes_[3:0] - supplies a test pattern ("Jazz").
//
//    This strucure viewed from the video prom, i.e. the system
//prom reads it taking into account PROM_Stride and PROM_Width
//follows:
//
//typedef struct _VIDEO_PROM_CONFIGURATION {
//    ULONG VideoMemorySize;
//    ULONG VideoControlSize;
//    ULONG CodeOffset;
//    ULONG CodeSize;
//} VIDEO_PROM_CONFIGURATION; *PVIDEO_PROM_CONFIGURATION;
//
//
//    VideoMemorySize - Supplies the size of video memory in bytes
//
//    VideoControlSize - Supplies the size of video control in bytes
//
//    CodeOffset - Supplies the offset in bytes from the beginning
//                 of the video prom to the first byte of code which
//                 is also the entry point of the initialization routine.
//
//    CodeSize - Supplies the size of the code in bytes.
//
//
//
//  Following this structure there is a IdentifierString -
//  Zero terminated string that identifies the video card "JazzG364", "
//  JazzVXL" ...
