What was added to autoexec.bat:
SET SOUND=C:\VIBRA16
SET BLASTER=A220 I5 D1 H5 P330 T6
REM SET MIDI=SYNTH:1 MAP:E

What was added to config.sys:
DEVICE=C:\VIBRA16\DRV\VIBRA16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5
REM DEVICE=C:\VIBRA16\DRV\CTMMSYS.SYS

I think these two are not essential for playing games. But they don't hurt / take up memory either.

Thanks, Phil. Looks like CTMMSYS.SYS does use 10kb.

Leave the SET lines alone, remove stuff from CONFIG.SYS. This is what I usually do.

Oh. Out it goes then 🤣

It seems if I rem out the VIBRA16.SYS line in CONFIG.SYS, sound effects stop working in games (music still works though).

Does DIAGNOSE complain about anything if VIBRA16.SYS is commented out?

Okay, making some progress. The reason digital sound weren't working with VIBRA16.SYS commented out was because I also commented out DIAGNOSE /S from AUTOEXEC.BAT. Once I re-enabled that, then sounds work without VIBRA16.SYS. Thank you, alexanrs.

I still don't understand why running DIAGNOSE.EXE (without /S) tells me that 330H is not available.

Probably because it is not: Some other PnP device might be grabbing it. Still, unless you use a daughterboard or an external module this is a non-issue, as OPL3 music doesn't use the MPU-401 UART interface.

Alright. I do have a DreamBlaster S1 on its way, so I will have to fix this. First stop is the BIOS. Thanks, alexanrs!

Is there a way to see what is using 330H? I haven't had any luck in the BIOS yet.

You can try Ultimate Boot CD, it some diagnostic programs that might help.

But could you tell us a bit more about the PC?

What is inside?

Hey Phil,

It is a Packard Bell C110 Multimedia. the only cards are a PCI Voodoo3 2000 and the ISA CT2800 Vibra. Other than that, there is a hdd and optical and floppy drive. I've tried two different ISA slots. I will next remove the Voodoo3 and use onboard VGA.

The drives are all IDE?

But it's an OEM machine. I'm thinking SCSI or Ethernet.

Check the BIOS and see if you can disable any on-board resources that you aren't using.

I've already done that: Serial A and B and Parallel are disabled.

Yes, the drives are both IDE.

Maybe a dumb question: but might I need to first have a daughterboard plugged in for 330H to be recognized in DIAGNOSE.EXE?

Nope. The interface is there regardless of any MIDI hardware being connected to receive it.

There are interesting settings in the bios that I am not familiar with but might be related to this.

Under Advanced Chipset there is ISA LFB Size. Dafault is Disabled. The other option is 1MB. If you enable this, then ISA LFB Base Address appears with a greyed out value of 15MB.

Under Plug and Play, configuration mode can be Use ICU (ISA Configuration Utility) or Use Setup Utility. When set to Use ICU, then Boot With PnP OS becomes available, with options for Win95 (Default), Other, and None. When set to Use Setup Utility, then an option for ISA Shared Memory Size appears with options ranging from 16KB to 96KB, or Disabled. If you pick a value (say 16KB) then you can select an ISA Shared Memory Base Address. The higher the memory size, the fewer options there are for base address. Lastly, when Configuration Mode is set to Use Setup Utility, options appear for IRQs 3-11 to set as Available, or Used By ISA Card.

I've tried various combinations of settings with no luck so far.

Oh, and I removed the PCI Video Card and am using onboard video. No change. 🙁

Did the Aztech modem/sound card come with the C110 from factory or does it have modem and sound on board?

Edit: Found my answer in your other thread.

As far as I know, the C110 came from the factory with the Aztech. There are no integrated ports for modem or sound.

The ISA LFB thing is for ISA VBE2+ graphics cards. It should be disabled in your case.
Anyway, do games with a sound setup/test utility (Duke Nukem and Warcraft II are good examples) succeed if you set them to use General Midi (and providing the correct port) instead of Sound Blaster/Adlib/OPL3? Or do they display an error message about being unable to initialize the MPU-401 interface?
