// 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
// +------------------+ +------------------+
// | reserved | | Board_Identifier | 0x00
// +------------------+ +------------------+
// | reserved | | PROM_Stride | 0x08

//
//
// 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" ...
