EISA FDDI Adapter Card Notes.

Release 1.403:
1. Added support for R10000 (IP28 64bit).

Release 1.4:
1. The EISA SGI adapter driver software Version 1.4 provides compatibility
   with IRIX Versions 5.1, 5.2, 5.3, 6.1 and 6.2.

2. The tool "fddistat" was modified so that the print for the "datavalid" field
   is in ascii instead of hex. Thus, it now shows "CDDI" when the print values
   are valid responses from the controller.


Release 1.3:
1. The EISA SGI adapter driver software Version 1.3 provides compatibility
   with IRIX Versions 5.1, 5.2, 5.3, and 6.1.  EISA SGI adapter software
   Version 1.2 is bundled with Version 1.3 for IRIX Version 6.0.1
   compatibility.

2. The tool "fddistat" was fixed so that time values are displayed
   correctly for IRIX Versions 6.0.1 and 6.1.  

Release 1.2:
1. A driver supporting R8000 64-bit operating system (IRIX 6.X) is now
   included.  Install script automatically determines which of the
   three drivers (corresponding to IRIX 5.1/5.2, IRIX 5.3, or IRIX 6.X)
   to load.  Install script also copies correct version of tools onto
   hard drive. 
   
2. Contains support for system tunable variables.  The following 
   driver variables have been changed to system tunable:  
   cfddi2maxcopysz, nfddi2txbufs, nfddi2rxbufs, fddimode0,
   cfddimtu, fddixdonecnt.  The default, min, and max
   values for these variables are listed in /var/sysgen/mtune/if_cfddi.
   To tune these variables, use the 'systune' command (see man page
   for 'systune').

Release 1.1:
1. Contains support for fddimode0. The ability for station to receive
   it's own broadcast frames. Need to set variable fddimode0 to 1 to
   enable this feature.
2. Has support for IRIX 5.3. Object module is if_cfddi.53.o.

Release 1.0:
1. Contains basic TCP/IP protocol support.
2. Contains IP multicast support.
3. Contains support for SMT 7.3
4. Adapter flash rom file version 3.6 is for turbo cards and is based on
   SMT 6.2.
5. Adapter flash rom file version 4.2 is for turbo cards and is based on
   SMT 7.3.

NOTES ON BYTE SWAPPED DAT TAPES:

1. tapes were created with the /dev/tape device which is the
   byte swapped device.
2. /dev/tapens is the no byte swap device.
3. /dev/rmt/tps1d3ns is also a no byte swap device.
4. /dev/rmt/tps1d3 is a byte swap device.
5. To byte swap a tape do the following:
   1. dd if=/dev/tape of=<file> conv=swab
   2. tar xf <file>

Requirements:
1. SGI Indigo 2 workstation.
2. An EISA slot must be available.
3. The workstation must be running IRIX release 5.1.1 or later.
4. The following filesets are dependencies:
   a. bsd

5. The fddi driver supports the INET address family for the IP protocol
   stack, including IP multicasting.

Installation:
1. login as root or super user.
2. insert source distribution media into tape drive.
3. cd /usr/local
4. tar xvf /dev/tape
5. cd cfddi
6. ./install.fddi
7. cd /
8. shutdown -y -g0
9. power off
10. add eisa fddi adapter to eisa bus in an empty slot.
11. power on.
12. verify fddi connections to concentrator, etc.

Deinstallation:
1. login as root or super user.
2. cd /usr/local/cfddi
3. ./deinstall.fddi
4. cd /
6. shutdown -y -g0
7. power off
8. remove eisa fddi adapter card.

RUNNING ttcp for tcp/ip performance numbers:

1. On receiving machine: ttcp -r -v -R65535 -l16384 
2. On transmitting machine: ttcp -t -v -S65535 -l16384 <remote hostname>

Bring Up Fddi Interface:

1. In file /etc/config/netif.options modify appropriate variables:
   if<x>name=fddi<num>
   if<x>addr=<hostname>

   where x = network interface number in system.
   where num = fddi interface number, which is eisa slot # - 1.

2. In file /etc/config/ifconfig-<x>.options add appropriate ifconfig options:
   up
   netmask

   where x = network interface number in system.

3. To verify the fddi ring is up, run ifconfig fddi<num> 
   If the flags set must include UP,RUNNING for proper
   communication to other nodes in the network.


TROUBLE SHOOTING and FDDI RING VERIFICATION:

1. ping to other nodes on network, ping to self.
2. see /var/adm/SYSLOG to verify card was seen on EISA bus at boot up.
3. ifconfig the interface to see if up and running.
4. look at status and ring op LEDs on adapter.
5. netstat to see if packets are coming in or out.
6. check cabling to concentrator.
7. fddistat to view fddi counters and states.
8. go to concentrator and view fddi variables with di port and di mac
   commands.
