Address (hex)

Description

 

 

 

C0000–FFFFFh ROM

256 KB BIOS in Flash EPROM, shadowed into DRAM during runtime.

 

 

C0000–EFFFFh

Run time user memory space. Usually, memory between C0000h and CFFFFh

 

is used for the BIOS of add-on VGA video cards.

 

 

A0000–BFFFFh

Normally used for video RAM as follows:

 

EGA/VGA

0A0000–0AFFFFh

 

Monochrome

0B0000–0B7FFFh

 

CGA

0B8000–0BFFFFh

 

 

00502–9FFFFh

DOS reserved memory area

 

 

 

00400–00501h

BIOS data area

 

 

 

00000–003FFh

Interrupt vector area

 

 

 

Memory beyond the first megabyte can be accessed in real mode by using EMS or a similar memory manager. See your OS or programming language references for information on memory managers.
