Installation instructions for the packet driver collection
Document conventions
All numbers in this document are given in C-style
representation. Decimal is expressed as 11, hexadecimal is
expressed as 0x0B, octal is expressed as 013. All reference to
network hardware addresses (source, destination and multicast)
and demultiplexing information for the packet headers assumes
they are represented as they would be in a MAC-level packet
header being passed to the send_pkt() function.
Using the packet drivers
The packet driver must be installed prior to use. Since
each packet driver takes only a few thousand bytes, this is best
done in your autoexec.bat. Since the Ethernet boards typically
have jumpers on board, the packet driver must be informed of the
values of these jumpers (auto-configure is possible, but can
disturb other boards). The first parameter is the software
interrupt used to communicate with the packet driver. And
again, because each board is different, the rest of the
parameters will be different.
All parameters must be specified in C-style representation.
Decimal is expressed as 11, hexadecimal is expressed as 0x0B,
octal is expressed as 013. Any numbers that the packet driver
prints will be in the same notation.
Before installing the packet driver, you must choose a software
interrupt number in the range between 0x60 and 0x80. Some of
these interrupts are used for other purposes, so your first
choice may not work. See Appendix A for the section of Ralf
Brown's interrupt list between 0x60 and 0x80.
Running a packet driver with no specifications will give a
usage message. The parameters for each packet driver are
documented below.
The -n option is used to convert IPX packets between the
Ethernet II type 8137 encapsulation used by BYU's PDSHELL IPX
interface code and the 802.3-style encapsulation normally used
on Ethernet by Netware servers, shells and boot PROMs. It will
also convert incoming type 8137 packets to type 8138 so that
Netware doesn't get confused.
The -d option is used to delay the initialization of the
Ethernet card until the packet driver is used for the first
time. See PROMBOOT.NOT for how to use -d and -n in a PROM boot
environment.
The -w switch is used for Windows. Install the packet driver
before running MS-Windows. This switch does not prevent Windows
from swapping your network application out of memory, it simply
detects when that has happened, and drops the packets on the
floor.
3Com 3C501
usage: 3C501 [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The 3c501 driver requires two additional parameters -- the
hardware interrupt number and the I/O address. The defaults are
3 and 0x300.
3Com 3C503
usage: 3C503 [-n] [-d] [-w] packet_int_no [int_level(2-5)
[io_addr [cable_type]]]
The 3c503 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the cable
type. The 3c503 can be attached to thick or thin Ethernet
cables, and the selection is made in software. The cable type
parameter should be zero for thick, and one for thin. The
defaults are 2, 0x300, and 1 (thin). The 3c503 uses shared
memory whose address is set by jumpers, but the software can ask
the board what the address is.
3Com 3c505
usage: 3c505 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The 3c505 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 2 and 0x300 and 0xd000.
3Com 3c507
usage: 3c507 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The 3c507 will determine its parameters by reading the
board. The only time you would need to specify the parameters
is when you have multiple 3c507s in the same machine.
The 3c507 driver will use three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address.
3Com 3c523
usage: 3c523 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The 3c523 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 3 and 0x300 and 0xc000.
ARCNET
usage: arcnet [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The ARCNET driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 5 and 0x2e0 and 0xd800. Note
that a packet driver client must specifically support ARCNET.
The only known client is Phil Karn's (KA9Q) networking package,
NOS.
AT&T
usage: at&t [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The AT&T driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 2 and 0x360 and 0xd000. This
driver supports the StarLAN 1, StarLAN 10 NAU, EN100 and StarLAN
Fiber NAU.
D-Link DE-600
usage: de600 [-n] [-d] [-w] packet_int_no
The D-Link Pocket Lan Adapter packet driver requires no
additional parameters.
Digital Equipment Corporation DEPCA
usage: depca [-n] [-d] [-w] <packet_int_no> [<int_no>
[<io_addr> [<mem_addr>]]]
The DEPCA packet driver requires three additional
parameters -- the hardware interrupt number, the I/O address,
and the memory base address. The defaults are 5 and 0x300 and
0xd000. The packet driver will resolve the io_addr
automatically if io_addr is set to '?', e.g.
depca 0x7e 5 ? 0xd000.
Mitel Express
usage: express [-n] [-d] [-w] <packet_int_no> [-n]
[<driver_class> [<int_no>]]
The Mitel Express packet driver has one optional switch,
and two optional parameters. The <driver_class> defaults to
SLIP, and the <int_no> defaults to 7. The -n switch instructs
card to be an NT. The <driver_class> should be SLIP or a
number.
HP EtherTwist/Starlan10/ThinLan
usage: hppclan [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The hppclan driver supports 8 and 16 bit HP LAN cards
based on the National 8390 chip. Earlier HP LAN cards should
use the 3Com 3C501 driver. The hppclan driver requires two
additional parameters -- the hardware interrupt number and the
I/O address. The defaults are 3 and 0x300. On IBM PS/2
Microchannel machines, the defaults are read from the PS/2
configuration NOVRAM and additional parameters are not
normally required.
IBM Token Ring
usage: ibmtoken [-n] [-d] [-w] packet_int_no [adapter_no]
The IBM Token Ring packet driver requires one additional
parameters -- the adapter number. The default is zero. See
IBMTOKEN.DOC for more information.
LocalTalk
usage: localtlk [-n] [-d] [-w] <packetintno> [<IP address>]
The LocalTalk packet driver requires atalk.sys to be
installed. Because it is not an Ethernet class driver, it
requires special code in the client. See LOCALTLK.NOT for more
details.
NCR ET-105
usage: ncret105 [-n] [-d] [-w] <packet_int_no> <int_no>
<base_addr> <Ethernet_address>
The NCR ET-105 driver requires four additional parameters
-- the hardware interrupt number, the I/O address, the memory
base address, and the Ethernet address. The Ethernet address
assigned to any particular board is printed on sticky labels
that come with the board.
Novell IPX
usage: ipxpkt [-n] [-d] [-w] packet_int_no
The ipxpkt packet driver simulates Ethernet on Novell IPX
protocol.
BICC Data Networks' ISOLAN 4110 ethernet
usage: isolan [-n] [-d] [-w] packet_int_no [int_no
[base_addr]]
The BICC Isolan requires three additional parameters --
the hardware interrupt number and the memory base address. The
defaults are 2 and 0xb800h.
Netbios
usage: nb [-n] [-d] [-w] packet_int_no ip.ad.dr.ess
[receive queue size]
The netbios packet driver transports IP packets over
NetBIOS.
Novell ne1000
usage: ne1000 [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The ne1000 driver requires two additional parameters --
the hardware interrupt number and the I/O address. The defaults
are 3 and 0x300.
Novell ne/2
usage: ne2 [-n] [-d] [-w] <packet_int_no>
The ne/2 driver requires no additional parameters.
Novell ne2000
usage: ne2000 [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The ne2000 driver requires two additional parameters --
the hardware interrupt number and the I/O address. The defaults
are 2 and 0x300.
Racal-Interlan (Formerly Interlan) NI5010
usage: NI5010 [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The NI5010 driver requires two additional parameters --
the hardware interrupt number and the I/O address. The defaults
are 3 and 0x300.
Racal-Interlan (Formerly Micom-Interlan) NI5210
usage: ni5210 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The NI5210 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 2 and 0x360 and 0xd000. Note
that Interlan sets the default memory base to 0xa000, which is
brain-damaged, because that area of memory is specifically
reserved for video adapters, and in fact the EGA and VGA use
it.
Racal-Interlan NI6510
usage: ni6510 [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The ni6510 driver has two additional parameters -- the
hardware interrupt number and the I/O address. The defaults are
2 and auto-sense. These parameters do not need to be set unless
the auto-sense routine fails, or otherwise disrupts operation of
your PC.
Racal-Interlan (Formerly Micom-Interlan) NI9210
usage: ni9210 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The ni9210 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 2 and 0x360 and 0xd000.
NTI 16
usage: nti16 [-n] [-d] [-w] packet_int_no [int_no [io_addr
[base_addr]]]
The nti16 driver requires three additional parameters --
the hardware interrupt number, the I/O address, and the memory
base address. The defaults are 3 and 0x338 and 0xd000.
SLIP8250
usage: SLIP8250 [-n] [-d] [-w] packet_int_no [-h]
[driver_class]
[int_no]
[io_addr] [baud_rate] [send_buf_size] [recv_buf_size]
The driver_class should be SLIP, KISS, AX.25, or a
number.
The SLIP8250 driver is not strictly an Ethernet adapter,
however some software packages (such as KA9Q's NET and NCSA
Telnet) support Serial Line IP (SLIP). SLIP must be specially
supported because it doesn't use ARP and has no hardware
addresses prepended to its packets. The PDS is not clear on
this, but the packet driver does the SLIP encoding. The
parameters are as follows. The -h flag is included if you wish
to use hardware handshaking (the packet driver will then suspend
the transmission of characters while CTS is low). The
driver_class is the class that is returned to a client of the
packet driver spec in the driver_info call. The int_no is the
hardware interrupt number, defaults to 4 (COM1). The io_addr is
the hardware I/O address, defaults to 0x3f8 (COM1). The
baud_rate defaults to 4800 baud. The send_buf_size and
recv_buf_size default to 3000 each.
Ungermann-Bass NIC-PC
usage: ubnicpc [-n] [-d] [-w] <packet_int_no> <int_no>
<base_addr>
The UB NIC-PC driver requires two additional parameters, the
hardware interrupt number, and the memory base address.
Ungermann-Bass NIC-PS/2
usage: ubnicps2 [-n] [-d] [-w] <packet_int_no> <int_no>
<io_addr> <base_addr>
The UB NIC-PS/2 requires three additional parameters -- the
hardware interrupt number, the I/O address, and the memory base
address. The defaults are the contents of the POS registers, so
the only time you would need to use the parameters is if you're
using two NIC-PS/2 boards in one machine.
Tiara Lancard
usage: tiara [-n] [-d] [-w] packet_int_no [int_no
[io_addr]]
The Tiara driver runs the Tiara LANCARD/E cards, both
eight and sixteen bit cards. The Tiara driver requires two
additional parameters, the hardware interrupt number, and the
I/O port.
Western Digital WD8003 E EBT EB ET/A and E/A
usage: WD8003E [-n] [-d] [-w] packet_int_no [-o]
[int_level [io_addr [mem_base]]]
The WD8003E driver runs the Western Digital E, EBT, EB,
ET/A, and E/A Ethernet cards. The WD8003E requires three
additional parameters -- the hardware interrupt number, the I/O
address, and the memory base address. The defaults are 2 and
0x280 and 0xd000. The wd8003 cards do not enable their memory
until configuration time. Some 386 memory mappers will map
memory into the area that the card intends to use. You should
be able to configure your software to leave this area of memory
alone. Also driver will refuse to map memory into occupied
memory. The occupied memory test fails on some machines, so the
optional switch -o allows you to disable the check for occupied
memory.
Errorlevels
Some of the packet drivers return error codes. Some of
these error codes indicate fatal errors, and some are merely
warnings. For the moment, you must consult the source to see
what the errorcodes mean. For example, pktchk returns 0 if a
packet driver exists at a given address, and 1 if not. You
might use it in a batch file that only installs a packet driver
if one is not found.
rem only install the packet driver if there isn't one
rem already.
pktchk 0x7e
if errorlevel 0 goto gotit
ni5210 0x7e
:gotit
The "errorlevel" test is true if the errorlevel is less
than or equal to the parameter.
Utility Programs
There are also several utility programs for packet
drivers:
PKTADDR
usage: pktaddr packet_int_no [ethernet_addr]
If the second argument is given, the Ethernet address of
the given packet driver is set. The Ethernet address is printed
out.
PKTALL
usage: pktall packet_int_no
All packets are received and discarded from the given
packet driver. This program is of most use with PKTMODE and
TRACE.
PKTCHK
usage: pktchk packet_int_no [packet_int_no]
Test for existance of a packet driver. Returns with
errorlevel 0 if the specified interrupt has a packet driver. If
the second argument is given, all interrupts in the range are
checked for a packet driver. If no packet driver is found at
all, errorlevel 1 is returned.
PKTMODE
usage: pktmode packet_int_no [receive_mode]
If the second argument is given, the receive mode of the
given packet driver is set. A decimal number from the list of
modes should be used. All the possible modes are printed out.
Unimplemented modes are marked with "xx", and the current mode
is marked with "->".
PKTMULTI
usage: pktmulti packet_int_no [-f filename | address ...]
The specified addresses are set as allowed multicast
addresses. If no list of addresses is given, then the current
list of addresses is printed. The
addresses may either be specified on the command line, or in a
file using the -f option. When a file is used, any whitespace
in the file is ignored.
PKTSTAT
usage: pktstat first_int_no [last_int_no]
The statistics for all packet drivers in the given range
are printed. The default range is 0x60 through 0x80. The
meanings of the columns are given below.
pkt_in is the number of packets ever received by this driver.
pkt_out is the number of packets ever transmitted by this
driver.
byt_in is the number of bytes ever received by this driver.
byt_out is the number of bytes ever transmitted by this driver.
pk_drop Packets dropped because there was no handler for that
Ethernet packet type.
err_in Dependent upon the packet driver.
err_out Dependent upon the packet driver.
PKTSEND
usage: pktsend packet_int_no [-r] [-f filename | packet]
The specified packet is sent using the specified packet
driver. The -r option says to repeat sending as fast as
possible. You shouldn't use this option very often. The packet
may either be specified on the command line, or in a file using
the -f option. When a file is used, any whitespace in the file
is ignored.
PKTRING
usage: pktring [-m] dest_packet_int_no src_packet_int_no
Test two packet drivers loaded on two Ethernet cards in
the same machine. Sends packets of every possible length using
the driver located at src_packet_int_no to the driver located at
dest_packet_int_no. If the -m switch is used, then the various
receive modes are tested. Note that the multicast tests (modes
four and five) do not work properly yet.
TERMIN
usage: termin [-s] packet_int_no
The specified packet driver is terminated, and its memory
recovered.
The s-option (stop) is used to prepare for termination.
The in-use flag for all handles are cleared. This prevents
upcalls to handlers that are to be removed and also makes it
possible to later terminate the packet driver even though
handles are not released. Actually, doing termin -s after prom
boot is like cutting the branch you are sitting on. Recipe for
removing packet driver, IPX and NET:
pktdrvr 0x7c ....
MARKNET C:IPX&NET3.MRK
PDIPX
NET3
. . .
NET3 u ; unload netx to avoid
communication timeout
TERMIN -s 0x7c ; pkt drvr no longer calls any
nonexistent rcvrs
RELNET ipxet3.mrk ; IPX is "removed"
TERMIN 0x7c ; It is now safe to terminate the
packet driver
TRACE
usage: trace packet_int_no [buffer_size]
Trace is very useful for debugging packet driver
troubles. Trace lets you trace all transactions between a user
program and the packet driver. The transactions are stored in a
memory buffer whose size is set with buffer_size. The default
size is 10,000 bytes.
When you run trace, it sets itself up and then spawns
COMMAND.COM so that you can run a network program that uses the
packet driver. After you quit your network session, you issue
an "EXIT" command. This returns you to trace, which writes the
transaction log to "TRACE.OUT". The following program, DUMP,
interprets TRACE.OUT.
DUMP
usage: dump
Interprets the contents of TRACE.OUT as written by TRACE.
