Hi Nick

I'd glanced that doc before but disregarded it too quickly because I
don't want to pay any money right now :)  It was well worth mentioning
as now that I've read it properly I can see that there's HW, ROMMON
and SW interaction all involved to support the larger sizes.  I guess
if I upgrade the SP ROMMON on the older Sup720 it might read the 1GB
CF card.  If I'm really keen, it may also be possible to find
reference to this in some IOS release notes.  Ideally, I'd buy that
kit so that no random person with access to my DC can push "eject" and
sabotage my boot.  I'd been looking into the CF support as I came into
possession of a handful of 1GB CF II cards that are too slow and weeny
for pics and tunes but right on par with the Sup720 model of storage.

Cheers
