### SYSTEM DATA - VIDEO PARAMETER TABLES

Notes: The default parameter table (see #01263) is located at F000h:F0A4h for 100% compatible BIOSes. Under PhysTechSoft's PTS ROM-DOS this table is fictitious.

    Format of video parameters:

    Offset  Size    Description     (Table 01263)
    00h 16 BYTEs   6845 register values for modes 00h and 01h
    10h 16 BYTEs   6845 register values for modes 02h and 03h
    20h 16 BYTEs   6845 register values for modes 04h and 05h
    30h 16 BYTEs   6845 register values for modes 06h and 07h
    40h    WORD    bytes in video buffer for modes 00h and 01h (0800h)
    42h    WORD    bytes in video buffer for modes 02h and 03h (1000h)
    44h    WORD    bytes in video buffer for modes 04h and 05h (4000h)
    46h    WORD    bytes in video buffer for mode 06h (4000h)
    48h  8 BYTEs   columns on screen for each of modes 00h through 07h
    50h  8 BYTEs   CRT controller mode bytes for each of modes 00h through 07h

Note: QEMM v7.5 Stealth appears to copy only the first 40h bytes of this table into always-accessible memory
