I have an Adaptec 1452C and a GUS, and I was having a similar problem with
Strike Command.  It appears that some games are too aggressive when they
search for a sound card.  The fix, in my case, was to answer 'no' to
'automatically detect sound card', and to install it manually.  I don't
know if that will work for you.

I have sent two or three mail messages to Gravis within the last two weeks.
All have been returned with the message"
	RETURNED MESSAGE ADVISORY -  NO REGISTERED USER BY THAT NAME AT THIS SITE.


Do you know if there is a problem with Gravis receiving mail or have the
e-mail addresses changed recently?

can somebody tell me the proper email address for gravis tech support? 
Everything I've tried has bounced.  (like tech@gravis.com, tech_1@gravis.com,
etc.)

Urp...that explains a LOT of weird things I've heard!! The chris*.mid 
files in particular use a lot of channels for chorus and echo effects.

On a separate subject, probably a FAQ, is there a simple way to enable 
the Line In so I can listen to audio CD's from *DOS*? The Windows driver 
(or somebody) disables it when exiting Windows: the CD keeps playing but 
the sound cuts off. I have a DOS utility similar to WinCD Pro to play 
the things but it doesn't have a clue how to enable the audio 
pass-through. (Yeah, I know I could write a utility to do it but I have 
to draw the line SOMEWHERE!)

As a matter of fact, my brother's machine has had an entire 4MB bank go
bad. He thinks it was due to heat, in that the power supply fan was
erratic...So it DOES happen...

Parity is rather simple. Each 8-bit byte as an extra bit devoted to parity
(hence the 9-chip SIMM [1 bit per chip] and the 3-chip SIMM [1 nibble per
SIMM with an extra 1 bit chip]). The number of 1's in this byte is added
and the parity bit is set to make that number 'even' or 'odd' depending on
the parity scheme. It's pretty good (it takes flipping 2 bits to have the
parity bit not change so this method will catch 1-bit errors). There are
much better methods available, but they tend to require either more
processor intervention and/or more bits to make them work (Hamming codes
are popular because they can detect and CORRECT errors)...

As far as I understand it, NMI stands for Non-Maskable Interrupt and it is
usually devoted to memory parity. However, it can be handled by someone
other than the system (SBOS in this case). I think what happens is that the
game writes to the SoundBlaster port, gets an error (after all, the port
isn't there!) which triggers an NMI. SBOS traps the NMI and if it's for the
SB ports, it handles it, otherwise it passes it on...But then, this is only
my guess at how it might work...

Message-ID: <MAILQUEUE-101.930722144152.384@subz-nov>

I downloaded GUS0033.ZIP (SBOS 2.B10) from EPAS yesterday. The zip-
file was corrupted. But when I tried from WUARCHIVE the same thing
happened. (I used IMAGE :=} for transfer). When I ZIPFIX it, I get a
few files, but SBOSDRV.SYS (or the like) is damaged.

Any hint? Did that happen to any other? If the file is corrupted (it
has only 78 K) could someone be so kind to upload a non-corrupted
version?

Thanks in advance,
SAM

Subject: Win 3.1 GUS Mixer control of Line-In and CD-In
Message-ID: <9307221759.AA11411@pima.intel.com>

Hello fellow GUS-ers,

I've been listening to the net and enjoying my GUS, but I've finally
come across a question I've found no answer to :

  - In Windows how can I control my GUS's Line-In and CD-In volume ?

The GUS Mixer on the v2.06 disks has no control of the CD input on the
card, and there is simply an ON-OFF switch for Line-In control.  I've
recently added a CD-ROM to my system, and I'm trying to get the audio
connection to the CD-ROM tied into the GUS.  The Line-In, with its
simple ON-OFF switch is just too loud in the ON position compared to the
.WAV and .MID controls which have volume sliders.

I hope there is an applet like my old SB-Pro had that let me adjust all
these sources under s/w control.

Any help would be appreciated !

To the author of Mega-Em..

I had a rather long message posted to the digest, but it was on that day
a week or so back that the digest barfed.

This message described why I'm suggesting what I'm suggesting, but here 
is the long and short of it.

Please do not make mega-em crippleware.  You are hurting your own
market by doing so.  If you do make it that, I will never buy it from you.
If you don't, I would consider doing so.  Maybe it's just me, but I will
not purchase a crippled program, partially it's just the way I think.

I guess to consolodate most of my thoughts into one statement,

How many of you would pay $50 for sbos?

I thought so.

In addition I have added a /L switch to EMUSET to enable the Ultrasound
Line in. Usefull for Sound Blaster owners.

There are two other new switches for EMUSET. /CO1 and /CO2. These are
designed to allow Mega-Em to be used in conjuction with a real MPU-401
interface. Could be useful for DOS based MIDI sequencers. I have no
means to test these, so they may not work.

Look for megem09b.zip on ARCHIVE.EPAS.UTORONTO.CA in
/PUB/PC/ULTRASOUND/SUBMIT.
