System Memory Map (continued)
4GB-128KB FFFE-0000 to FFFF-FFFF
Notes:
1 Not all video modes are used at the same time. You can save some
memory by defining which video modes you are using. Typically,
0B-0000H to 0B-7FFFH is only used when you attach a monochrome
monitor. Both the text and graphic VGA modes are often used when you
attach a VGA monitor.
2 You can remap the video BIOS to 0C-0000H using the SETUP program or the
System Configuration utility if your applications require the video BIOS to
reside at that location. Do not enable remapping to 0C-0000H unless your
application requires it; this saves 32KB of memory for other uses. The
built-in video BIOS is always located at 0E-0000H.
3 You can shadow external ROM BIOS information to memory between
0C-0000H and 0D-FFFFH using the SETUP program or the System
Configuration utility. The option allows you to begin the shadow block at
each 16KB boundary.
4 Some memory managers, such as move the extended BIOS
data area from 09-FC00H to a lower address in base memory to provide
more contiguous memory above the area used by MS-DOS.
