I think they are devices that stored a primary and alternate boot image (with a single root file system).

Perhaps even a primary and alternate u-boot image as well.

(Flash storage hardware wasn't trusted so much, back in those days.)

I still have a backup copy of twobob's DX - on a per-device basis.
There are 14 storage devices (or partitions) on the DX.
I'll push that copy to kpool/dxg in case you want to look at it.
(It will probably be safer there anyway, I am about to perform major surgery on my own PC's storage system.)

Edit:
Working, should be there in about 1-1/2 hours.

Sorry for the thread hyjack, but here, from mach-mx3/mario.c
