Note:
At least 128 K byte of memory is always assigned to Expanded memory.
A block of 128 K byte in the reserved memory area can also be assigned to Expanded memory. The
Expanded Memory Manager (EMM) manages the interface between the program and Expanded memory,
bringing data in and out through the page frame as required. Before you can use Expanded memory, you must
install the EMM4J.SYS device driver, as described below.
You do not need to install the Expanded memory driver unless your application program supports use of
Expanded memory.
Device Drivers
Four device drivers used for managing memory are included in ROM. They are:
EMM4J.SYS -
device driver that supports LIM-EMS Expanded memory.
HIMEM.SYS -
device driver that supports the use of Extended memory for storing a Terminate and Stay
Resident (TSR) program or device driver.
RAMDRIVE.SYS -
device driver that supports RAM disks in conventional, Extended and Expanded
memory.
