LEDs Green and Amber
Green on - Card
initialized, SMT running, connected to network. May be
problems at higher level protocol layers, but card can
communicate with other stations.
Amber on - Card initialized
and SMT running, card NOT connected to network. Possibly
cable troubles or neighboring station is down.
Green and Amber Off - No
board driver has been loaded and SMT not running.
Note: When an
SK-52xx is used in a 16-bit slot, the SK-52xx can only
access the first 16MB of RAM and may not work properly
in systems with more memory.
0083 "SK-NET FDDI-FM/FDDI Network Adapter"
I/O Port Address Location
Each FDDI adapter installed is assigned a
unique address location.
0600-07ff, 0a00-0bff, 1200-13ff, 2200-23ff, 4200-43ff,
8200-83ff, fe00-ffff, fa00-fbff, f600-f7ff, ee00-efff,
de00-dfff, be00-bfff, 7e00-7fff
This adapter can operate on one of four
interrupt levels: 3, 9, 10, or 11
9">, 10, 11, 3
EPROM Address location
There are 7 possible 16K blocks of PC
memory that can be assigned for accessing the EPROM area
of the FDDI Network adapter.
Disabled">, C4000-C7FFF, C8000-CBFFF,
CC000-CFFFF, D0000-D3FFF, D4000-D7FFF, D8000-DBFFF,
Remote boot on/off
Enables/disables booting from network.
boot on">, Remote boot off
Bus Master Arbitration Level
Each Busmaster and/or DMA device is
assigned an unique arbitration level in order to
arbitrate conflicting requests.
8">, 9, 10, 11, 12, 13, 14
Each participant is assigned a priority by
arbitration level .
Priority defines sequence of granting the bus on
conflicting requests. The latency time on bus requests
Fairness off: Higher priority
gives more time on the bus. The latency time on
bus requests is NOT calculable.
ON">, Fairness OFF
Streaming data enable/disable
data disable>, Streaming data enable
Check on forbidden 8-Bit
Working as busmaster the adapter supports
accesses to 32-Bit and 16-Bit memory slaves. If the
adapter performs an access to an 8-Bit slave an
interrupt may be asserted and reported (check on) or not
on">, Check off
Working as busmaster the adapter may check
the control line 'CHCK'. If the check is enabled the
adapter asserts an interrupt and reports this event.
