Scrolling Mode
The Formula Color™ display adapter allows the application to write on a virtual 25
lines by 80 columns display. On the other hand, the user can see only a portion of
this virtual display at a time, which we call the physical display.
The "scroll" parameter controls which portion of the virtual display is seen by the
user. The display can always be scrolled by the application program.
Software: the physical display position is fixed. It can be moved only by the
application program.
Track: the physical display follows the cursor vertically only through BIOS.
Virt: it is only possible to scroll the display by the keyboard.
Both: Both the Virtual and Track mode are enabled.
Contrast
The CMOS value of LCD contrast represents the only parameter that can be
modified outside the BSETUP.EXE application. As a matter of fact, selecting the
contrast mode [FUNC]-[4] gives you the ability to change this value using the up and
down arrows; this changing does not affect the EEPROM value.
