KIT CONTENTS:

This distribution kit contains the Windows 95 device driver for
the DEC FDDIcontroller/PCI adapter.

INSTALLATION:

For general installation instructions, refer to the manual(s) that
came with Windows 95.  Read the section that describes the installation
of network cards.

From the Network option under Control Panel, select "Add" then "Adapter".
This will display the "Select Network adapters" dialog box.  Select the
"Have Disk" button, then enter "A:\" after inserting the DOS-based
driver diskette that came with your DEC FDDIcontroller/PCI adapter.  The
driver and installation file will be copied to the appropriate system
file area once you leave the Network dialog box.

CUSTOMIZATION:

For most configurations, no customization of the driver should be necessary.
However, a number of parameters are available for users to change by first
selecting "Properties" after highlighting the desired DEC FDDIcontroller 
under the Network dialog box.  Next, select the "Advanced" option under the
Properties dialog box, then use your mouse and keyboard to change the
default settings per the following descriptions.

"Burst Size" affects the adapter longword burst size.  The default is
16 longword burst, but this parameter can be used to lower the value.
Lowering this parameter may impact driver performance, so care should
be taken before modifying this parameter.

"Receive Buffers" affects the maximum number of host receive buffers that 
can be used by the adapter at a time.  Although this number is small, 
increasing it is not likely to increase performance because the adapter 
itself provides a large amount of receive buffering (~1MByte).

"Transmit Buffers" affects the maximum number of map registers that can be
allocated by the adapter.  During packet transmission, an NDIS_PACKET may be
comprised of several NDIS_BUFFERs where each NDIS_BUFFER requires a map
register for physical DMA (Direct Memory Access).  The default of 32 is 
within NDIS 3.0 specification, but the adapter may be able to handle more 
outstanding transmit packets if this value is increased.  However, map
registers are a limited system resource and arbitrarily increasing this 
parameter may make this adapter or other adapters in the system unusable.
Arbitrarily lowering this parameter may impact driver performance or cause
undesired behavior.  CARE SHOULD BE TAKEN BEFORE MODIFYING THIS PARAMETER!

"Static Transmit Buffers" affects the maximum number of static transmit
buffers that are available to the driver.  As mentioned in the "Transmit
Buffers" parameter description, for maximum performance, the driver DMA's
directly from the NDIS_BUFFERs in an NDIS_PACKET.  Should the NDIS_PACKET
be comprised of too many NDIS_BUFFERs, or the adapter descriptor table is
full, the driver will attempt to buffer copy the outgoing packet into one
of the static transmit buffers.  The default value is kept low because
the driver will normally not encounter the situation where it needs to
buffer copy the packet during transmission.

"Full Duplex Enable" affects the eFDXEnable MIB value.  Digital FDDI adapters 
are in Full-Duplex (FDX) mode when the mode setting is enabled and the
adapter is connected point-point with another similarly enabled FDDI adapter 
or the Digital GIGAswitch FDDI switch.  FDX mode takes advantage of the 
point-point connection by removing the FDDI token and allowing simultaneous 
receive and transmit of packets.  FDX mode will help reduce latency and may 
increase network throughput if the system is nearing the standard FDDI 
maximum throughput.

"Requested TTRT (4-165)" affects the MACTReq SMT MIB object.  FDDI selects
the target token rotation time during the claim process (eg. when an FDDI
node has entered or left the ring).  During this time, each FDDI node offers
its requested TTRT (MACTReq MIB object) and the lowest bidder wins.  
Normally this parameter does NOT need to be modified from the default of 
8ms.  However, some installations may set this value arbitrarily high on 
end node stations so that the requested TTRT can be more easily managed 
from an FDDI concentrator or switch.  For this reason, the range of 4-165ms. 
is supported with a default of 8.  This parameter should only be modified 
by experienced FDDI network managers.  

"Maximum Frame Size (3-4478)" affects the maximum FDDI frame size (not
including media header) that the driver will advertise to the protocol
stacks.  By default, the maximum size is 4478 bytes.  However, there
may be a need to lower this parameter.
