7.8 Display Driver

7.8.1 Function

Display driver (VGA_C.DRV, VGA_NC.DRV) is a Windows display driver for a screen size of

192 x 384 dots. If this driver is used, maximized or iconized windows will not extend beyond the

screen size and dialog boxes can be displayed in the center of the screen.

The relationship between the Display driver and application programs is shown in the following

diagram.

7.8.2 Startup Method

Display Driver can be loaded by making the following specification in the [boot] section of

SYSTEM.INI. VGA_C.DRV or VGA_NC.DRV are included in SDK. If Windows is installed by

the installer, VGA_C.DRV will be automatically copied into the F-ROM drive (D:) and

SYSTEM.INI is also automatically created. Therefore, the user does not have to be concerned with

this setup process.
