VX-Net - AEMM.SYS and AMLOAD.EXE

Recent versions of VX-Net (including the current release, 3.14) give the option to define a workstation as using the 286 expanded memory driver AEMM.SYS. For historical reasons, NETGEN will append /p:,4 /r to the DEVICE=AEMM.SYS line in the CONFIG.SYS file that is produced for the workstation, giving :-

DEVICE=AEMM.SYS /p:,4 /r

Version 4.02 of AEMM.SYS (as found on recent DOS System Disks, and in VX-Net 3.14) does not need these switches, and so they should be edited out, leaving just:-

DEVICE=AEMM.SYS

in CONFIG.SYS.

Also, we would advise that version 4.02.04 (beta) of AMLOAD.EXE be used, as this version will detect that AEMM.SYS is loaded and will not over-write the memory used by AEMM.SYS, unlike earlier versions.

The use of AEMM.SYS and AMLOAD.EXE together will result in the loss of 64K of memory to AMLOAD, as AEMM.SYS sets up a 64K page frame in the memory that AMLOAD would otherwise have used. This will mean that on a XEN-S, for example, AMLOAD will be restricted to 128K of memory, as opposed to the 192K it would otherwise have had available. This may have implications on applications being loaded, as there will be less above memory to load the network stack into, causing more network software to be placed into conventional memory, and therefore reducing the amount of conventional memory available after logging on.

AEMM.SYS Version 4.02 is available on the Apricot Technical Support Bulletin Board in File Area 42, and AMLOAD.EXE Version 4.02.04 (beta) is available from the BBS in File Area 38.
