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.
