Anyone got docs or at least jumper settings for an

Floppy Controller? I just found one and it works (or at least it loads its
BIOS on boot) and so I'd like to get it going.
I'm gonna try to run it in an AT&T 6300.
Thanks!

The Omni-Bridge card that I have has the switch setting information
silk-screened adjacent to the relevent switches. However, by way of
confirmation:
Switch 1 selects drive type. Positions 1 & 2 select for drive A, and
positions 3 & 4 select for drive B.
360KB 1.2MB 720KB 1.44MB
5.25" 5.25" 3.5" 3.5"

Switch 2, positions 1 & 2, selects BIOS address.

Position 3 selects I/O address.

Position 4 selects whether 1.2MB drive is fixed or dual speed.

The two 3-pin Berg headers near the top of the bracket control power
through the external connector. The jumpers should normally occupy the
left two pins of each header which is power off.
There is a 360K floppy of files that go with the card. I will send you
a ZIP file of its contents by private email.
