I have an AT&T 6386/SX WGS (16 MHz 80386SX box). It comes with 2 MBytes
of RAM, which it calls:
	640Kb	basic memory
	384Kb	dedicated memory
	1024Kb	extended memory
During its setup, you can enable/disable shadow RAM for both the BIOS
and the EGA/VGA ROM. You can also specify that the remaining dedicated
memory can be used as extended memory. I have done so, and during the
bootstrap it claims that 256Kb have been moved from dedicated to extended
memory.
