 +====== Marconi (formally Fore) PCA-200E PC nic -- Centos 6.5 ======
 +
 +Work done on Centos 6.5, see this page for Ubuntu 12.04:- FIXME
 +
 +
 +===== Driver and firmware =====
 +
 +Driver fore_200e is not included in stock Centos kernel, but is available in ''​kernel.i686 0:​2.6.32-431.23.3.el6.centos.plus''​
 +
 +This can be installed by enabling Centos Plus in the repo directory.
 +
 +After a reboot, ''#​ uname -a''​ gives:- ''​Linux neptune.rainsbrook.xxx 2.6.32-431.23.3.el6.centos.plus.i686''​
 +
 +lsmod shows:-
 +<​code>​

 +atm                    38492  1 fore_200e
 +</​code>​
 +
 +But dmesg shows:-
 +<​code>​
 +[root@neptune ~]# dmesg | grep fore
 +fore200e: FORE Systems 200E-series ATM driver - version 0.3e
 +fore_200e 0000:​01:​0b.0:​ PCI INT A -> GSI 21 (level, low) -> IRQ 21

 +Turns out that no firmware was available to load (strace is your friend to see this)

 +Card now appears to work OK!

 +Now trying to initialise the card seems to work:-

 +[root@neptune ~]# atmsigd -u uni31+uni30 ​ -l /​var/​log/​atm/​atmsigd.log -m user -b -d
 +[root@neptune ~]# ilmid -b -d -v -l /​var/​log/​atm/​ilmid.log -u 3.1
 +</​code>​
 +
 +gives this on a Marconi ASX200bx switch when plugged in to port 1a1:-
