TokenExpress(TM) Adapter: Driver Installation, IBM - AS400 Connectivity
IBM AS400 CONNECTIVITY
This file contains instructions specific for the installation and
operation of Intel's TokenExpress adapter driver. Refer to the
appropriate Network Operation System documentation for any NOS-specific
questions or other information.
These instructions apply to Release 5.0 of the software.
Installing and configuring the Intel TokenExpress adapter DLC driver for
IBM Environments.
General Guidelines
The TokenExpress adapter installation program (INSTIBM.BAT) is dependent
upon whether or not your application requires the IBM Netbios protocol.
If Netbios is NOT used, the installation program creates a \NETWORK
directory on the specified destination drive and copies the TokenExpress
adapter DLC driver (OC02DLC.SYS) and the TokenExpress interrupt
arbitrator (OC01IA.SYS) files into it.
If Netbios IS required, the IBM interrupt 5c arbitrator (DXMA0MOD.SYS)
and the Netbios (DXMT0MOD.SYS) files are copied to the \NETWORK
directory along with the TokenExpress adapter DLC driver (OC02DLC.SYS).
The IBM interrupt 5c arbitrator and Netbios files are found on the IBM
LAN Support Program diskette (must be purchased from IBM Corporation).
To install the TokenExpress adapter DOS DLC driver, do the following:
1. Insert the Intel adapter driver diskette #2 into drive A:.
2. Run the TokenExpress adapter driver installation program by typing:
A:\IBM\DOS\INSTIBM src dest
where "src" is the drive containing the driver diskette and "dest"
is the drive where the files will be written. For example,
A:\IBM\DOS\INSTIBM A: C:
3. Follow the directions on your monitor to complete the installation.
4. Remove the Intel driver diskette from drive A: and reboot your
system.
If you require NETBIOS, the INSTIBM.BAT file copies the IBM
interrupt 5C arbitrator (DXMA0MOD.SYS) and the NETBIOS
(DXMT0MOD.SYS) files to the \NETWORK directory instead. The
TokenExpress DLC driver is always used.
Note: f you do not require NETBIOS, the INSTIBM.BAT file creates a
\NETWORK directory on the destination drive and copies the TokenExpress
adapter DLC driver (OC02DLC.SYS) and the TokenExpress interrupt 5C
arbitrator (OC01IA.SYS) files to it.
5. Complete your installation for AS400 using the IBM installation
guides.
Special Considerations
An optional country code can be specified when loading the interrupt 5C
arbitrator OC01IA.SYS. Drivers loaded subsequently may then use this
country code to display messages in the selected language.
The country code is specified in the CONFIG.SYS file as follows:
device = (path)\OC01IA.SYS <optional country code>
The supported values are:
01 US English
45 Danish
49 German
The TokenExpress DLC driver supports four (4) optional parameters.
These parameters are specified in the CONFIG.SYS file as follows:
device = (path)\OC02DLC.SYS -E<...> -N<...> -L -A
The parameter definitions are:
-E<AdapterNumber><EarlyRelease>
AdapterNumber identifies the adapter as either primary or secondary (0 =
primary, 1 = secondary).
EarlyRelease enables/disables Early Token Release. ETR is enabled by
default (0 = enable, 1= disable). This parameter is ignored if the date
rate is 4 Mbps.
-N<AdapterNumber><NodeAddress>
AdapterNumber identifies the adapter as either primary or secondary (0 =
primary, 1 = secondary).
NodeAddress - Zero (0) or a locally administered node address. A '0'
forces the use of the adapter's burned-in address (BIA) and overrides an
application's use of a local address. The locally administered node
address is a 12-digit hexadecimal number starting with 4, 5, 6 or 7.
-L causes the driver to copy all transmit data into a local buffer
before transferring it to the network. It may be necessary to use this
with the TokenExpress ISA Adapter if all of the following conditions are
met: 1) the adapter is configured as a Bus Master, 2) an expanded memory
board is installed, and 3) the application transfers data directly from
expanded memory to the network. In addition, this parameter may be
needed if the expanded memory manager does not support VCPI and/or the
DPMI standards.
Specifying this parameter causes the driver to use more memory and
should only be specified if necessary. Do not use this parameter if the
adapter is configured to operate in programmed I/O mode.
-A causes the driver to treat the first adapter found as the secondary
adapter (1) and ignore any other adapter. If this parameter is not
specified, the adapter with the lowest I/O address setting is
automatically designated as the primary adapter (0) and the other
adapter is the secondary adapter.
Example: To configure a system having two TokenExpress adapters with
locally administered addresses (the first adapter using address
400000001066, the second adapter using 400000002067 and having Early
Token Release disabled), the following entry would be placed in your
CONFIG.SYS file:
device=<path>\OC02DLC.SYS -N0400000001066 -N1400000002067 -E11
Using the Intel TokenExpress 16/4 adapter in PC Support/400 DOS Extender
Workstations
When installing a TokenExpress adapter in a PC Support/400 DOS Extender
workstation, an I/O address conflict results if the default address is
selected. This conflict originates from the PC Support/400 memory
manager, which reserves I/O address (A20) for an IBM Token-Ring adapter.
If any other adapter is present at that address (determined by reading
the adapter's Burned-In-Address), the PC Support/400 program will fail.
Changing the I/O address for the TokenExpress adapter to one of the
alternate addresses (A24, A50, A54) will eliminate the conflict and
allow proper operation of the PC Support/400 program.
Notes for use with Qualitas' 386MAX Memory Manager
The 386MAX Memory Manager program allows physical memory above 1 Meg to
be mapped into the address space between the video RAM and the BIOS ROM.
You can free up conventional DOS memory by loading DXMA0MOD.SYS,
OC02DLC.SYS and DXMT0MOD.SYS into this area.
Additional considerations:
* The driver may not work if 386MAX is used to backfill the lower 640
Kbytes (used if your 80386 machine does not have 640K low DOS
memory without the 386MAX).
* Automatic recovery of unused shadow RAM by 386MAX should be
disabled when using the TokenExpress MCA adapter because the shadow
RAM may not be accessible. This is done by adding the "noxram"
parameter to your existing 'device = 386max.sys' statement as
follows:
device = 386max.sys noxram
* Do NOT use the option 'EMS=0' when installing 386MAX.SYS. If using
386MAX version 4.08 or higher, you may use the NOFRAME option
instead.
* The 386MAX program provides an VCPI interface. The DLC drivers
should work with similar products that support the VCPI standard.
