840-PD.COM [Options]
(A) The 840-PD.COM is a packet driver on DOS:
To run the 840-PD.COM directly on the DOS prompt -
driver:\> [driver:\path\]840-PD.COM<enter>
(B) Functional Description:
1) Supported functions for FTP1.09 spec. are
driver_info(), access_type(), release_type(), send_pkt(), terminate(),
get_address(), reset_interface(), get_parameters(), set_rcv_mode(),
get_rcv_mode(), set_multicast_list(), get_multicast_list(),
get_statistics(), and set_address().
2) The input options are
(2.1) 840-pd [packet_int_no[id=xx_xx_xx_xx_xx_xx]
[nway=off/on][full/half][ls=10/100]
[bl=0/1/2/4/8/16/32][ca=8/16/32][tt=0/0x01--0x7f]]
(2.1.1)
id=xx_xx_xx_xx_xx_xx physical address
nway=on(off) autonegotiation function
full full duplex
half half duplex
ls=100(10) line speed
bl=0(1,2,4,8,16,32) burst length
ca=8(16,32) cache alignment
tt=0(0x01--0x7f) transmit threshold
where (1) packet_int_no, tt, and id values are hex.values
and forms as 0xXX (ie:0x12)
(2) other values are digit
(3) 'full' and 'half' do not co-exist
note:
a. The parameter 'full' and 'half' is used to set the full
duplex function of the 840 adapter.
This adapter can be in half or full duplex mode. So 'full'
and 'halt' do not co-exist. In half duplex mode, the W89C840
can only either transmit or receive. In full duplex mode, the
W89C840 can transmit and receive at the same time.
If user does not set 'full' or 'halt' in the command line,
this driver will auto detect the full duplex function.
b. The parameter 'ls' is used to set the line speed.
This adapter can be operationed in 10M or 100M Mbps. The
reasonable values is 10(set as 10M) or 100(set as 100M).
If user does not set this parameter, this driver will
auto detect the line speed.
c. The parameter 'bl' is used to set burst length.
The default value of the burst length is 6.
Burst Length defines the maximum number of long words that
can be transferred within one PCI burst transaction. The
reasonable values are are 1(1 longword), 2(2 longwords),
3(4 longwords), 4(8 longwords), 5(16 longwords) and
6(32 longwords).
7. The parameter 'ca' is used to set cache alignment.
The default value of cache alignment is 3.
Cache Alignment defines the address boundary for data burst.
The reasonable values are 1(8 longword alignment),
2(16 longword alignment) and 3(32 longword alignment)."
8. The parameter 'tt' is used to set transmit threshold.
The default value of transmit threshold is 0.
This value decides the transmit threshold level of the
transmit FIFO. Transmission will start immediately after the
transmit FIFL has reached the threshold level or full pkt has been
transferred to the transmit FIFO if the frame length is less
than the transmit threshold level.
TxThreshold Transmit Threshold Level
00H full pkt
01H 16 bytes
02H 32 bytes
-- --
7FH 2032 bytes"
9. The parameter 'nway' is used to disable or enable the
autonegotiation function. The default value of nway is on.
The reasonable values are OFF and ON.
(2.1.2) packet_int_no is the software interrupt number,and in the
range 0x60 through 0x80 (including 0x60 and 0x80).The
default value is 0x60 (0x60 means 60h).
(2.2) 840-pd -U/-u packet_int_no
the parameter 'U' or 'u' may unload this packet driver using this
specific packet_int_no.
(2.3) 840-pd ?
show message about user interface (2.1), and (2.2).
3) The rule for unload this driver is :
to unload this driver staying in that packet_int_no.
4) The rule for working on LAN cards (one card or more cards) is :
in program initialization stage, we will scan the same Winbond packet
driver from 0x60 to 0x80 (suppose there have N Winbond packet driver
before us), and remember their slot number.
If the user has not specified ethernet ID ,the driver will be
loaded on the Winbond LAN card which slot number are the smallest
and different from the N Winbond LAN cards.
If the user has specified ethernet ID ,the driver will be loaded
on the card that the user selects. If the driver has been loaded
on this card, "the driver has been loaded" message will be shown.

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
