OK, this time I downloaded the correct ISO.
Installed 64 bit version A-OK.
The NICs in the box are:
2 x Broadcom BCM5716
4 x Intel Gigabit
When installing I chose management interface marked as UP.
System boots OK.
IFCONFIG shows the interface as OK.
However I cannot PING it, (or PING out).
I have tried the Broadcom and Intel NICs in 32 and 64 bit mode in other install attempts.
Kind of stalled now as I'm unable to get to webmin etc.
Any ideas?
