EXAMPLE OF HOW TO LOAD 3COM NETWORK HIGH
========================================
NOTE: MINSES pre: 1/27/86 and NB (NetBios) pre: 8/12/87 will not
work. If you have these you must update these.
Please remember that every system configuration is different and
so the example is here only as a guide. Don't follow it blindly !
Nothing beats reading the manual, then the General Network
Installation file and read.me file on disk.
Appllication Notes for use of ALL Chargecard on a PS/2 Model
30-286, 50, 50Z or 60 running 3COM+ or 3+Open DOS Workstation
software.
Configuration 1 - 3+ DOS workstation OR
(see also config.w3p and autoexec.w3p)
3+Open DOS workstation - XNS protocols
(see also config.w3o and autoexec.w3o)
Full NetBIOS or partial (not shown)
Windows/286 (No EMS, no Smartdrive)
VGA
1MB of Motherboard Memory
3COM Etherlink/MC network adapter.
Configuration 2 - 3+ DOS workstation OR
(see also config.3p and autoexec.3p)
3+Open DOS workstation - XNS protocols
Full NetBIOS or partial (not shown)
VGA
1 MB of Motherboard Memory
3COM Etherlink/MC network adapter
*** Caveats:
On 3COM's 3+ network operating system, if full NetBIOS must be
loaded high, you must use NetBIOS 1.2.1H, available for 3+
customers from 3COM by dialing XXX-XXX-XXXX.
(This module is included with 3COM 3+Open systems)
INSTALLATION AND CONFIGURATION PROCEDURE - Configuration 1.
1) Install the ALL Chargecard hardware per instructions. Follow
the instructions very carefully.
2) Use the IBM PS/2 Model 30-286 or 50/60 Reference diskette to move
the Packet Buffer RAM of the EtherLink/MC card to address
C000-C5FF.
3) Add
device=<path>\allemm4.sys /RAM /FR=NONE /X=C000-C5FF /EXT=64
line to config.sys. Do not load any Network drivers high at
this time.
/RAM - tells allemm4 to find any available logical RAM between
640K and 1MB. On a 286 PS/2, VGA memory (A000-AFFF, and
B000-BFFF) is not available, neither is ROM BIOS memory
(RAM will give you useable memory between B000 and B7FF
if it is free)
/X=C000-C5FF - excludes the 24K RAM Packet buffer area of the
EtherLink/MC card. This leaves the largest
contiguous area (104K) available (C600-DFFF)
/EXT=64 - Reserves the first 64K of extended memory (above
1MB) for use by himem.sys. Note ALL Computers
have developed their own XMS driver to replace
himem.sys. (Release date 15th March 1989)
4) Install Windows/286, telling it that extended and expanded memory
are available.
5) Add remaining lines to config.sys and autoexec.bat per the
appropriate config and autoexec files. The first line of
config.sys MUST be "device=himem.sys". (If you are using the
ALL Computers XMS driver, use as instructed) The second line
of the config.sys MUST be the "device=<path>\allemm4.sys..."
line. The remaining "device=..." lines are in autoexec.bat.
ALL's operating software includes its own "device", "files",
"buffers", and "lastdriv" commands. That's why these are in the
autoexec.bat rather than the config.sys.
The ALLOAD command loads COM and EXE files high
3+Open only: In the \3open\doswksta\lanman\lanman.ini file,
find the line containing the "redir" command. Add to the front
of it the full path to the ALLOAD command:
i.e. \<path>\alload redir .....
6) At this point you may want to experiment with loading drivers in
different spots to obtain best fit; you may also use the PS/2
reference disk to move the location of the Packet Buffer RAM.
Don't forget to change the /X=...parameter of the
"device=allemm4.sys...." line of the config.sys to reflect the
new location. Use the alload, device, or examem commands
interactively with no parameters to look at how memory is used.
Useful parameters to load drivers in different places are:
device /LM - loads driver into low memory (below 640K)
device /AF - Assigns (loads) driver into First available segment
device /AT - Assigns (loads) driver into starting from top of
memory
alload /sg:xxxx - loads EXE or COM file to specific loacation
*** Experiments have shown that spp.sys wants to be loaded first
using the /AF command. The order of the other device drivers
does not matter, but the included autoexec.bat were designed
to obtain best fit.
INSTALLATION AND CONFIGURATION PROCEDURE - Configuration 2
This is exactly the same as Configuration 1 except that your
config.sys first line should be as follows:
device=<path>\allemm4.sys /RAM /FR=NONE /X=C000-C5FF
You are not running Windows, so you do not need device=himem.sys
or ALL Computers XMS driver.

Further Examples:
Example 1: IBM PS/2 50 VGA Token Ring Adapter Card with 3270
Connection Adapter running 3COM - Usable DOS available
672K after 3COM and the 3270 emulator have loaded high.
The Token Ring Adapter Card ROM and RAM were set using
the Reference Disk to C800-CDFF (see Token Ring file
on this disk on Token Ring card settings)
TIPS: With VGA & EGA we can steal 32K from the Video
Buffer at B000-B7FF.
In some machines we can steal another 32K at
F000-F7FF. (You cannot do this in a PS/2)
With this particular example, the user did not
want High Resolution Graphics so we were able to
include the 92k from A000-B7FF. (see CONFIG.SYS
below)
CONFIG.SYS
files=20
buffers=20
lastdrive=g:
device=allemm4.sys x=c800-cdff fr=none i=a000-b7ff ram
NOTE: i=a000-b7ff can be used because this user was not using
High Resolution Graphics, if you are using High Res
Graphics then you should use i=b000-b7ff
fr=none basically says that you haven't got an EMS page
frame, if you need an EMS pageframe then you should leave
this out and the ALL Chargecard will automatically
default to giving you a 64k Page Frame
x=c800-cdff excludes the Token Ring adapter card ROM and
RAM which have been set to these locations by the Reference
Disk - (look in the Token Ring file for info on Token
Ring Adapter settings)
The ALL Chargecard automatically excludes the 3270
Connection Adapter RAM between CE00-CFFF
Files and Buffers have been left in the Config.sys because
with 3COM, the Network Card ROM & RAM, the 3270 emulator
all high, there wasn't enough space for them up there.
Normally you would load them through your Autoexec.bat
file.
AUTOEXEC.BAT
echo off
device /AF =spp.sys
device /AT =pro.sys 12 2 2
device /AT =buf.sys
device /AL =tokibm.sys
device /AT =idp.sys
device /AL =lgl.sys
runminds mindspro mindsbuf mindseth mindsidp mindsspp mindslgl
alload /sg:d400 nb
MINSES
msredir /z:4096
set comspec=c:\command.com
setname $$com$$
prtsc
if exist start.bat start
NOTE: If you are using a IBM Token Ring Card with the IBM 3270
Connection Adapter, their position in the BUS is critical.
The IBM 3270 Connection Adapter should be in Slot 1
(nearest the outside casing), the IBM Token Ring Card
should be in Slot 2 next door to it.
TIPS
----
In your Config.sys, if you are using a Clone Machine,
there is the possibility of stealing some more memory
from the F segment by using i=f000-f7ff in your
ALLEMM4.SYS statement - it is worth trying
If in trouble go back to basics.
Start with only DEVICE=ALLEMM4.SYS RAM in your
Config.sys file, nothing else.
Then after booting up, use ALLOAD <cr> from your command
line to observe High memory.
Then one by one load the software high, using Alload
and Examem to see what you have done. Some software won't
run high, so load it low.
Unfortunately trial and error tend to produce the optimum
system. Generally people make mistakes like not excluding
their network card ROM & RAM or trying to load software
where there is no free memory or NOT READING THE
MANUAL or READ.ME file on the disk.
