From article <487@tardis.Tymnet.COM:, by jms@tardis.Tymnet.COM (Joe Smith):
: I believe that all controllers will boot off of DF0: if there is a bootable
: floppy there and will boot from the hard disk if DF0: is empty.
: 
: But if there is a non-bootable DOS floppy in DF0:, my system shows the
: "insert Workbench 1.3" hand instead of falling back to DH0:.  Someone told
: me that the A2090A controller does this right.  I can force the Overdrive
: card to boot from the hard disk by holding down the left mouse button, but
: this requires manual intervention.

	My Supra system does this right also. If the floppy in DF0: is
bootable, you boot from it, if it's not a bootable floppy, you boot from
the HD.

: How many autoboot disk controllers make DH0: avaliable when you boot
: from floppy?  That is, being able to boot a game or an application from
: its floppy and have DH0: available for reading and writing even though the
: floppy has no mountlist and no mount commands in the startup-sequence.
: I've heard that C-Ltd has this feature.

	Again, this happens with the Supra also. You get the your boot
partition even when you boot on a floppy that doesn't have your HD
software in it. The only way I know to disable this is to leave the
drive powered down when booting. (My drives are external, so I can do
that...) Remember that having that partition mounted uses some memory.

: Any other semi-undocumented features out there?

	How about the fact that you can hook two machine to the same
hard drive and access the drive from both? I know the C-Ltd and Supra
both do this, and I imagine pretty much any of the SCSI controllers
should. Note that drives that have been set up for the Hardframe, Supra
or A590 can all be read interchangably also...
