;
; The Microfield T8/2 High Resolution Graphics Controller provides a
;  resolution of 1280 X 1024 pels or 1024 X 768 pels.  It provides for
;  display of the PS/2 VGA Graphics on the same monitor by means of
;  capturing the VGA video data and expanding it to a full screen display.
;
; The T8/2 is capable of driving two classes of monitors.  Which class of
;  monitor is chosen is configured with a jumper.  The jumper is neccesary
;  because the VGA video data must be correctly displayed even if the
;  normal POS configuration fails.
;
;    The two classes of monitors are:
;      1.   64 Khz, Non Interlaced, Fixed Horizontal Frequency Monitor.
;           High  Resolution, 1280 X 1024 Pels.
;                 VGA video data is captured at 31 Khz non-interlaced
;                    and displayed at 64 Khz non-interlaced.
;                 MCGI High Resolution Mode is displayed at 64 Khz
;                    non-interlaced.  (64 Khz non-interlaced specific
;                    microcode required.)
;
;      2.   31 Khz Horizontal Frequency Monitor.
;       a.  High Resolution, 1024 X  768 Pels, Non-Interlaced Multi-Sync
;              Monitor Capable of Accepting Horizontal Frequencies in the
;              Range of 31 KHz to 48 KHz.
;                 VGA video data is captured and displayed
;                    at 31 Khz non-interlaced.
;                 MCGI High Resolution Mode is displayed at 48 Khz
;                    non-interlaced.  (48 Khz non-interlaced specific
;                    microcode required.)
;
;       b.  High Resolution, 1024 X  768 Pels, 31 Khz, Interlaced, Fixed
;              Horizontal Frequency Monitor
;                 VGA video data is captured and displayed
;                    at 31 Khz non-interlaced.
;                 MCGI High Resolution Mode is displayed at 31 Khz
;                    interlaced.  (31 Khz interlaced specific
;                    microcode required.)

	pos[0]=XX0XXXXXb

;
; The POS byte is formatted as follows:
;    ( The Power Up Default In All Cases Is Zero.  This May
;      Or May Not Be The Same As The Recommended Setting. )
;
;
;     Bits 7 & 6 select the Interrupt Channel as follows:
;
;        76 <- Bit Position
;
;        00 - Disable Interrupts
;        01 - Interrupt Channel  9    ( Recommended Setting )
;        10 - Interrupt Channel 10
;        11 - Interrupt Channel 11
;
;
;     Bit 5 is Reserved and Must Be Undefined:
;
;        5 <- Bit Position
;
;        X - Must Be Undefined    ( Fixed Resource, Always Zero )
;
;
;     Bits 4 & 3 select the DMA Channel & Arbitration Level as follows:
;
;        43 <- Bit Position
;
;        00 - DMA Channel 7  &  Arbitration Level 7    ( Recommended Setting )
;        01 - DMA Channel 6  &  Arbitration Level 6
;        10 - DMA Channel 5  &  Arbitration Level 5
;        11 - ( Equivalent to 00, But Do Not Program )
;
;
;     Bit 2 selects whether the T8/2 is enabled for VGA capture mode:
;
;        2 <- Bit Position
;
;        0 - Enable  the T8/2 for VGA Operations    ( Recommended Setting )
;        1 - Disable the T8/2 for VGA Operations
;
;
;     Bit 1 selects the I/O port address for the T8/2 Command/Status Register:
;
;        1 <- Bit Position
;
;        0 - Use 030D for Command/Status Register
;        1 - Use 03DD for Command/Status Register    ( Recommended Setting )
;
;
;     Bit 0 is the Card Enable Bit and Must Be Undefined:
;
;        0 <- Bit Position
;
;        X - Must Be Undefined    ( Set & Reset By Configuration Manager )
;
