•
BIOS1352 can be used in conjunction with a Monochrome Display Adapter (mono) card. The standard DOS
command MODE MONO will switch to the mono card and the DOS command MODE CO80 will switch to the LCD
panel.
•
BIOS1352 emulates mode 3, but any program that attempts to write directly to video memory, bypassing the video
BIOS, will not display correctly.
•
BIOS1352 can be used in conjunction with a VGA BIOS. In this case all TTY output will be displayed on the VGA
monitor.
•
When the SED1352 video memory is specified as 64K bytes, the SED1352 video memory will reside at D000h to
DFFFh. For 128K bytes of SED1352 video memory, the memory will reside at C000h to DFFFh.
