Ah, No I didn't realise they were 2 different operations DOH!
So I tried again.
I reflashed with the original CompactFlash zip from IREX then (once that was completed successfully) modified the config.txt file so it only contains "format" (without the quotes) and did the reflash process again (Booting with the Connect button pressed).
According to the log file, both operations seem to have completed OK.....
....But still no WIFI
Did I do it right????
