I should have mentioned that.  I currently have 2 sup720-3bxls to test. 
I formatted two brand new 1GB CF cards (while running 12.2(18)SXD7 from 
sup-bootflash) and downloaded IOS to both CF cards in the first sup. 
After a bit of testing, we pulled that sup and put in the second.  We took 
one of the CF cards from the first sup and inserted that in the second 
sup...so I didn't format the card in this supervisor...but in another 
roughly identical supervisor running old code.

ATA MONLIB INFO
    Image Monlib size = 73144
    Disk monlib size = 55296
    Name = NA
    Monlib end sector = NA
    Monlib Start sector = NA
    Monlib updated by = NA
    Monlib version = NA

That doesn't look quite right.  After formatting again under 
12.2(18)SXF12, I have:

ATA MONLIB INFO
    Image Monlib size = 73144
    Disk monlib size = 77312
    Name = c7200-atafslib-m
    Monlib Start sector = 2
    Monlib End sector = 144
    Monlib updated by = s72033_sp-ADVIPSERVICESK9_WAN-M12.2(18)SXF12
    Monlib version = 1

Our current production sup720s running 12.2SXD software don't show 
anything about ATA MONLIB when you do a show disk all.  Does this mean 
that when we eventually upgrade them to 12.2SXF, to reliably boot, we'll 
need to reformat their CF cards as soon as we've upgraded?

Also, can you use 4GB CF cards in a sup720?  They tell me 4GB was all they 
could find locally.  There appear to at least be some cosmetic 
issues...but they format and boot.

They don't show up in "show file sys"

They don't report space used/free in dir disk:

and there appears to be some signed integer overflow in show disk:

Would these be unsafe to use in production...or are the issues likely just 
cosmetic?
