Figure 7-7: Graphics-Device VGA Sub Device Properties Dialog
In Figure 7-7
,
the
BIOS File
option enables you to load different VGA BIOS ROMs into
the device. The VGA ROM is assumed to be a maximum of 32-Kbytes, and is assigned to
ISA bus address 0x000C0000 - 0x000C7FFF, which is the industry-standard location.
This file must be a standard binary file, with the correct header and checksum
information already incorporated.
The VGA enabled
checkbox enables or disables the VGA registers. If it is not checked,
the VGA registers are not updated and the display window will not display from the
VGA frame buffer.

accelerator is enabled by default.
