AI-LANBIOS Low-level Driver for the Intel 82593 MLM hardware and derivatives
(INTEL593.DOC)
----------------------------------------------------------------------------

Introduction
============
The INTEL593 low-level AI-LANBIOS driver for Intel's "82593-MLM hardware
and derivatives" was developed by Intel Corp. in conformance with the
specifications outlined in the Artisoft AI-LANBIOS Driver Development Program.
The low-level driver interfaces directly to the network hardware and
provides basic unreliable data transfer capabilities. The AI-LANBIOS
high-level driver provides the reliable data transfer capabilities
including all NETBIOS functions.
The INTEL593 driver makes use of two system DMA channels for data transfer
operations. It also requires memory from the system memory space for its
transmit and receive buffers. This approach does not require any memory on
the board.
NOTE: As two DMA channels are used by one "82593-MLM hardware",
it is not possible to have more than one INTEL593 driver installed
in the same system.
Compatibility Statement
=======================
Version 3.10 of INTEL593 is compatible with Artisoft's LANtastic/AI Network
Operating System v4.1, except for the following functional considerations:
-INTEL593 driver requires two additional command line switches for its use
of system DMA channels.
-If a NETID Block is found on the computer in which the 82593 is installed,
the parameter values obtained from NETID Block will override the command
line switch values.
Vendor Information

Running INTEL593
================
The INTEL593 low-level driver must be run before the AI-LANBIOS. The
INTEL593 driver interfaces to the AI-LANBIOS using a DOS multiplex
interrupt number. The default multiplex number is C7. If you are only
running one low-level driver and one copy of AI-LANBIOS then you will
not have to worry about which multiplex number to assign. Multiplex
numbers 00 through BF are reserved for DOS use so you must use a multiplex
number between C0 through FF.
One invocation of the INTEL593 driver supports one "Intel 82593-MLM hardware
or derivative". Multiple copies can not be run as enough DMA Channels are
not available.
The INTEL593 low-level driver program name is INTEL593.EXE. The syntax for
INTEL593 is
INTEL593[switches . . . ] [ ; comment]
where [switches . . . ] denotes zero or more optional command line switches.
Switches may be delimited by blanks or slashes (/). If a switch takes a
value, the switch must be followed by an equal sign (=) or a colon (:).
Some values may be hexadecimal numbers while other values may be decimal.
All switch values are range checked and illegal values produce errors.
You may place a comment on the command line by preceding the comment with
a semicolon (;). You must precede the comment character with a blank.
The valid switch formats are:
SWITCH
SWITCH:value
/SWITCH
@file
The valid INTEL593 switches are enumerated below. The letters "ddd"
denote a decimal number. The letters "hh" denote a hexadecimal number.
Values enclosed in [] indicate default values if the switch is omitted.
Values after [] denote the valid range of the switch.
----------
@switch-file
This option specifies that further switches are to be taken from an
switch file. Any switches after the @switch-file name will be used,
and the switch settings take precedence over any settings in the switch
file. You may invoke switch files from within switch files as often as
you wish. The file should contain valid switches and may contain comment
characters (;) at the beginning of each line or after switches.
For example,
INTEL593 @setup
The file SETUP contains
; INTEL593 AI-LANBIOS driver setup file
IOBASE=300 ; Use I/O address 300
verbose ; Display verbose information
----------
HELP or ?
This switch displays information about the valid command line switches,
but does not install the INTEL593 driver. For example,
INTEL593/help
INTEL593 ?
See the messages section for a detailed description of the HELP display
output.
----------
XEROX [OFF]
This switch specifies that support for XEROX style packets has to be
provided. Specifying this switch will force the driver to transmit only
XEROX style packets.
NOTE: This doesn't affect the receive operation. The driver will continue
to receive IEEE802.3 style packets.
----------
IOBASE=hhhh [300] 0000-03e0
This switch specifies the I/O base address configured on the hardware
containing Intel 82593.
The IOBASE switch value must match the value specified on hardware.
The default value is IOBASE of 300.
Unless you have changed the settings on the hardware, the IOBASE switch is
unnecessary, as the driver default is same as the factory default.
----------
TX_DMA=dd [6] 6-7
This switch specifies the DMA Channel used for Transmit Commands. You will
need to change this value only if the DMA Channel 6 is being used by some
other application in your system.
----------
RX_DMA=dd [7] 6-7
This switch specifies the DMA Channel used for Transmit Commands. You will
need to change this value only if the DMA Channel 7 is being used by some
other application in your system.
----------
IRQ=dd [10] 2-10
This switch specifies the IRQ level used by hardware to interrupt the CPU.
You will need to change this value only if IRQ 10 is being used by some
other application in your system. But make sure that it matches the jumpered
IRQ on the hardware.
----------
MPX=hh [C7] C0-FF
This switch specifies the multiplex (MPX) interrupt number to use for
communication to the high-level AI-LANBIOS. You will need to change this
value only if the MPX number is in use by another application or low-level
driver.
----------
PACKET_SIZE=dddd [1500] 574-1500
This switch specifies the maximum size of transmitted IEEE 802.3 packets.
You may need to change this value when using certain bridges that do not
support the full 1500 byte packet size. Even when you reduce the packet
size, the low-level driver can still receive large packets.
----------
REMOVE
This switch removes INTEL593.EXE from memory. You must remove TSR programs
in the opposite order they were loaded. For example, if you loaded
INTEL593.EXE and then AILANBIO, you must remove AILANBIO before INTEL593.EXE.
For example if you have loaded
INTEL593.EXE
AILANBIO
To unload these copies of INTEL593.EXE and AILANBIO:
AILANBIO/REMOVE
INTEL593.EXE/REMOVE
The REMOVE option will remove the most recently run copy of AILANBIO.
----------
VERBOSE
This switch causes the INTEL593 driver to be installed and detailed
information about the configuration of the INTEL593 driver to be displayed.
See the messages section for a detailed description of the verbose output.
INTEL593 messages
=================
The INTEL593 driver produces two types of messages: Informative and Error.
All error messages are preceded by the text "ERROR:" and cause the INTEL593
driver not to be installed.
--------

This message appears when the HELP or ? switch is used. Each valid switch
is listed with the acceptable range of values (if any) and the base (hex
or decimal) that the numbers must be entered in. The acceptable file size
range for indirect files (@) is also listed. The low-level driver is not
installed when this switch is used.
--------
MESSAGE:
---- MLM-82593 AI-LANBIOS Compatible driver removed ----
The INTEL593.EXE driver has been removed from memory.
--------
MESSAGE:
Reading Configuration Parameters from NETIDBLK
The NETID Block was found in the memory. The parameters read from the NETID
Block will override any other specified parameters.
--------
ERROR: MLM-82593 Board is not responding to initial setup. Check
Configuration.
Meaning: The initial configuration of 82593 is not successful.
Remedy: Check that the configuration parameters for the hardware are OK.
Wrong IOBASE, TX_DMA or RX_DMA may cause this message to appear.
--------
ERROR: MLM-82593 Configuration failed
Meaning: The initial configure command issued to 82593 is not successful.
Remedy: Contact your Network support.
--------
ERROR: MLM-82593 Individual Address Setup failed
Meaning: The initial IASETUP command issued to 82593 is not successful.
Remedy: Contact your Network support.
--------
ERROR: MLM-82593 AI-LANBIOS Compatible driver is not loaded
Meaning: You have issued the INTEL593/REMOVE command and do not have
INTEL593.EXE loaded into memory.
Remedy: Only issue this command after the program is loaded.
--------
ERROR: Can't REMOVE -- interrupts re-hooked
Meaning: You have attempted to remove INTEL593.EXE and the interrupts are
in use by another TSR, or INTEL593.EXE was not the last TSR
loaded.
Remedy: Remove any TSRs loaded after INTEL593.EXE. For example, if you
load INTEL593.EXE then AILANBIO.EXE, you must first remove
AILANBIO.EXE, then you can remove INTEL593.EXE.
--------
ERROR: Installed AI-LANBIOS Compatible driver is different version
Meaning: You have loaded a version of the INTEL593.EXE program and
attempted to remove it from memory with the /REMOVE switch. The
version with which you are attempting to remove INTEL593.EXE is
not the same version that was loaded.
Remedy: Remove INTEL593.EXE with the same version of the program that was
loaded.
--------
ERROR: MPX number hh is already in use - Try another number
Meaning: Multiplex (MPX) interrupt number hh is being used by another
application or low-level driver.
Remedy: Try another MPX number.
--------
ERROR: No network hardware found at I/O base address ????H
Meaning: The MLM-82593 hardware could not be located. This error message
appears displayed because the adapter card is not present or the
IOBASE specified on the command line is different from what is
jumpered on the adapter.
Remedy: Check to see that the IOBASE switch specified on the
INTEL593.EXE command line matches the I/O Address setting on the
hardware.
--------
ERROR: Illegal switch - ??????=nnnn
Meaning: The switch ??????=nnnn is not a recognized switch.
Remedy: You may only specify legal switches on the command line.
--------
ERROR: Illegal character after switch name - ??????xnnnn
Meaning: The switch ?????? is followed by a character other than "=" or
":" or the switch does not take a value.
Remedy: Only use the characters "=" or ":" to specify switch values and
do not place characters after switches that do not take values.
--------
ERROR: Switch value not in range - ??????=nnnn
Valid range is ssss to eeee
Meaning: The value nnnn is not in proper range. The value ssss
represents the lowest acceptable value and the value eeee
represents the highest acceptable value.
Remedy: Limit your range of values to the acceptable range.
--------
ERROR: Illegal digit in switch value - ??????=nnnn
Meaning: An illegal digit (character) was encountered in the numeric
switch value.
Remedy: You must restrict numeric decimal values to the numbers 0-9.
You must restrict hexadecimal values to the numbers 0-9 and the
letters A-F.
--------
ERROR: Cannot open indirect file - @file
Meaning: The file "file" cannot be opened as an indirect file.
Remedy: The file must exist before it can be used as an indirect file.
Testing INTEL593 return code (error level)
========================================
You may test the INTEL593 return code or error level in a batch file by
using the IF ERRORLEVEL command. The following error levels are returned:
