Hi Nick, thanks for the swift reply. I'm based in UK.
So, to be clear I should
1) Transfer V5.6 from my Mac to the Compact Flash card via the USB to Compact Flash adapter.
3) Place the Compact Flash card into a PCMCIA-CF adapter.
4) Insert into H8000FW and start the software update process.
Are there any specific types or sizes of Compact Flash that will not work with the H8000FW? And any other tips in terms of formatting the Compact Flash cards in the Mac or the Eventide?
