W840ND.SYS
Winbond Electronics Corporation
Description:
1. W840ND.SYS is a NDIS 3.x driver for Windows NT 3.5 and 3.51.
If there is only one 840 card, the driver will automatically get IOBASE
and IRQ from PCI Configuration Space.
If there is more than one 840 card, user can indicate a specified 840
840 card by inputing IDs.
If user does not input an ID to select a specified 840 card, this driver
will automatically select a free 840 card to load.
2. OEMSETUP.INF is a Network Setup Information File.
Installation:

f. Restart your system.
3. There are 6 parameters can be set as you like, otherwise just use default
values.
a. BurstLen = 32 dwords
Burst Length defines the maximum number of long words that can be
transferred within one PCI burst transaction.
The reasonable values are "1 dword", "2 dwords", "4 dwords",
"8 dwords", "16 dwords" and "32 dwords".
b. CacheAlign = 32 dwords
Cache Alignment defines the address boundary for data burst.
The reasonable values are "8 dwords", "16 dwords" and "32 dwords".
c. Threshold = full packet
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.
The reasonable values are "full packet", "16 bytes", "80 bytes",
"96 bytes", "128 bytes", "256 bytes", "512 bytes" and "1024 bytes".
d. LineSpeed = AutoDetect
This adapter can be operationed in 10M or 100M Mbps.
The reasonable values are AutoDetect(auto detect line speed by the
driver), 10M(set the line speed is 10M) and 100M(set the line speed
is 100M).
e. FullDuplex = AutoDetect
This adapter can be in half or full duplex mode. 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.
The reasonable values are AutoDetect(auto detect full duplex function
by the driver), Disable(disable full duplex), and Enable(enable full
duplex).
f. SelectedID
This parameter is necessary when your system is equipped with
multiple W89C840 cards. For each driver, you must assign a unique
physical address. The value of this parameter is a hexadecimal string
of 12 digits.
Trouble Shooting
1. Message: 'At least one service or driver failed during system startup.
Use Event Viewer to examine the event log for details.'
Solution: Make sure
a. your 840 card is plugged into your system, or
b. if there is more than one 840 cards, you must indicate a
specified 840 card by inputing IDs.
