Note that the port address must be the same as the physical address set on the S5D13503 evaluation board.
Example:
13503BIOS d=color g=256 i=8 m=128 p=310 t=single x=320 y=240 f=2
Comments
•
13503BIOS can be used in conjunction with a Monochrome Display Adapter (mono) card. The standard DOS
command MODE MONO will switch to the monochrome card and the DOS command MODE CO80 will switch to
the LCD panel.
•
13503BIOS emulates mode 3, but any program that attempts to write directly to video memory, bypassing the video
BIOS, will not display correctly.
•
13503BIOS can be used in conjunction with a VGA BIOS. In this case all TTY output will be displayed on the VGA
monitor.
•
When the S1D13503 video memory is specified as 64K bytes, the S1D13503 video memory will reside at D000h to
DFFFh. For 128K bytes of S1D13503 video memory, the memory will reside at C000h to DFFFh.
