VGA Frame Buffer Size

#"
The STPC implements a single memory subsystem for both the system as well
as the frame buffer memory. In other words, the size of the DRAM available to
the system is reduced by the size of the DRAM allocated to the frame buffer.
The lower range of the DRAM, starting from the DRAM address 00h, is allocated
to frame buffer. The rest of the memory is used by the system.
#" ISACLK
Set the speed of the ISA bus here. The settings are tied to the speed of the PCI
bus. If the PCI bus operates at 33 MHz, a setting of PCICLK/4 (default) would
yield an ISA bus speed of approximately 8 MHz, the standard speed of the ISA
bus. While most devices operate at higher ISA bus speeds, try a slower bus
speed if your ISA device does not function properly.
#)

Some option ROMs do not operate properly
when shadowed.
