For all those having problems with the new SBOS 1.23, please contact
Gravis and let them know what your problems are. Remember to be detailed
about what you are doing and what the problem is.
The email address for Alan, the tech guy, is 71333.350@compuserve.com.
Let them know so that they can keep fixing it till we get a perfect
SBOS. Gravis is putting in their effort with wild distribution. Let's
give them our effort as well.
As for me, I've gone back to SBOS 1.22. I found that this worked 99.9%
of the time which is about perfect and is sure better than the latest
1.23.
Thomas.

When I had my SB and GUS coexisting, I made sure that none of the IRQs,
DMA channels, and ports overlapped. It looks like your TB IRQ and GUS
MIDI IRQ are that same. Try changing your MIDI IRQ to something else.

The GUS will conflict with every Adlib-compatible device because it
maps some of its registers onto ports 388h and 389h, the Adlib ports.
With the SB, I found that the GUS's registers masked the SB's own
Adlib registers at these locations, and thus, games wouldn't recognize
that there was an Adlib-compatible card in my machine. SBOS sets the
GUS registers that map onto the Adlib ports to values that the real
Adlib would return. These values would linger in the registers even
after SBOS was uninstalled. As a result, games that checked locations
388h and 389h for the presence of an Adlib card would then sence one.
I don't know by what mechanism the GUS's registers at the Adlib locations
were interfering with the SB's. It might be a pull high or a pull low.
If it's a pull high, then storing all zeroes into these two registers
would eliminate the interference. It it's a pull low, then storing FFh
will do it. If it's opaque masking, then some "Adlib values" would have
to be placed into the GUS's "Adlib" registers. A program could easily
be written to allow the GUS to coexist with SBs and TBs more peacefully
by placing appropriate values into the registers which mapped over the
Adlib registers. SBOS alread puts "Adlib values" into these registers,
but if the conflict is a result of a pull high or a pull low instead of
opaque (or complete) masking, then 00h's or FFh's would be much better.
[Disclaimer: The above two paragraphs depict what I believe to be going
on inside the GUS. I can't guarantee the accuracy of any of it, as I
don't know for sure what the Ultrasound is all about. Nobody does.]

I've tried my best to explain what I think is going on. I hope what I've
typed will give you some ideas of what to do now.

To: Ultrasound Daily Digest <ultrasound@dsd.es.com>
Is there any truth to the rumour that Microprose is supporting the GUS
in native mode? I had also heard that they were going to release a
driver for World Circuit which is already on the market.
Fingers crossed,
