To workaround the original issue, an IO Controller was installed, which works very nicely. Only downside is having different serial/aux ports.

nvram stays the same.
bootflash stays the same.
slot[01]/disk[01] become available
more ethernet ports become available
No bandwidth points are consumed so nothing needs to change slots.

Not a bad arrangement.

Interestingly enough, we did see an issue with a variant of CF flash that caused the boothelper, an older 12.3 image, to crash while booting with that CF in the IO controller, even as a fully booted IOS had no issue reading,writing,formatting it.

A slightly older CF worked fine. An upgraded boothelper probably would have also solved the issue.

The CF slot on the NPE-G1 (disk2:) seems to be toast.

Cisco on the older boxes used a non-FAT flash file system the key is
whether the flash is referred to as slotX or diskX. if the nomenclature
is slotX it uses a proprietary disk format which cannot be read by an
external reader.

to format CF card for use with older system

format slot0:

Are the alternate CF cards formatted correctly for your platform?

Probably. However, IOS doesnt seem to think there is any card there or
worse, it hangs upon insert.

The original CF card may have gone bad but if you're sure the other CF
cards are OK then they may be formatted wrong.

The card is fine, tested in external reader. They are all fine.

Thanks.
