System Memory Map (continued)

4GB-128KB

FFFE-0000 to FFFF-FFFF

Notes:

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.

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.

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

QEMM-386JM

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.
