I use an AT&T PC6300 Plus (80286 based) PC with a 2Meg expanded memory card.
I use the AEMM.SYS driver to access it.
I use the AEX.SYS driver to allocate 1Meg of the expanded memory as extended
memory and then make that 1Meg into a ramdisk with RAMDISK.DEV.
I use SMARTDRV.SYS to establish a 512K Cache in expanded memory.
The remaining 512K of expanded memory is available as expanded memory for
whatever program wants to use it.

I also allocate the "upper" 384K of the 1Meg on the motherboard as
another ramdisk.
(I think RAMDRIVE.SYS and SMARTDRV.SYS are from MicroSoft).

Here is a fragment of my config.sys.

device=C:\DRIVERS\RAMDRIVE.SYS 384 /U
device=C:\DRIVERS\AEMM.SYS
device=C:\DRIVERS\AEX.SYS 1024
device=C:\DRIVERS\RAMDISK.DEV /M=1024/E/DIR=128
device=C:\DRIVERS\SMARTDRV.SYS 512 /a
