Distribution is RH7.3 on an IBM pc server 330
-warm boot no
-cold boot yes, lights on the hub (a 10baseT) indicating activity and
collisions are continuously on from pressing the power button til
'bringing up eth0' message is  displayed and no activity lights are on in
the NIC during this time.

When running vortex_diag eth0 was as it were brought
up at boot.

[root@fisrv002 root]# less /etc/modules.conf
alias parport_lowlevel parport_pc
alias eth0 3c59x
# parameters added by AG 12.11.2002
# options 3c59x debug=1 full_duplex=0 options=9
alias eth1 pcnet32
alias scsi_hostadapter aic7xxx
alias scsi_hostadapter1 ips
alias scsi_hostadapter2 ips

After uncommenting parameters in modules.conf I did /etc/init.d/network
restart. Is the an acceptable method btw? At least I can see the module
loaded with those parameters.

Then I tried using mii_diag like this:
[root@fisrv002 root]# ./mii-diag -f -F 10baseT-HD
Using the default interface 'eth0'.
Setting the speed to "fixed", Control register 0000.
Basic registers of MII PHY #0:  0000 0000 0000 0000 0000 0000 0000 0000.
  No MII transceiver present!.
 Basic mode control register 0x0000: Auto-negotiation disabled, with
 Speed fixed at 10 mbps, half-duplex.
 Basic mode status register 0x0000 ... 0000.
   Link status: not established.
 Link partner information is not exchanged when in fixed speed mode.
   End of basic transceiver information.

But the configuration has not changed anywhere, I must have missed
something here:
[root@fisrv002 root]# ./vortex-diag -aemf

Also when I did ./mii_diag -R it caused the Ethernet to be flooded as in
cold boot so that I had to go to the console and restart the network.

Hope this information brings us further, and thanks for the efforts so
far.
