I am getting somewhere with the problem now, just removing the Roland LAPC-I card was not enough, I had to remove it from device manager as well, as soon as I did this, problem solved! so there is obviously a conflict between the two cards even thought the Roland is not a sound card as such it's a MIDI card. Any idea how to make these cards co exist?

Glad to see you have this posted here and on EAB.

So does it make a difference which ISA slot either card is installed into ?

Sadly not, I have tried it in both slots and with two separate cards

Old hardware posts should be in the Marvin forum. This forum is for Windows games.

Moved.

Thanks and sorry guys

I would suggest they have a conflict at I/O 330, that is the default I/O address for the MIDI interfaces for both cards. I would change the port address on the AWE64.

I second that. You have to change either AWE64, or LAPC-I MIDI port from 330h to another value.

I appreciate your help, when I have both cards plugged in these are the settings I get:

SB AWE64:
Interupt Request 09
Direct Memory Access 03
Direct Memory Access 07
I/O Range 0240-024F
I/O Range 0300-0301
I/O Range 0388-038B

Roland LAPC-I:
I/O Range 0330-0331

As you can see the port on the AWE64 is 0300 not 0330, so I am still baffled!

The interrupt request could be the problem, the LAPC-I defaults to 2/9, and your AWE64 is also at 2/9. Windows apparently doesn't show the IRQ, but that doesn't mean the conflict doesn't exist. You should change the AWE64's.

Thanks that may be worth investigating, I'll check tomorrow and report back

Just reporting back, sadly changing the IRQ did not work. I have given up at the moment, I have removed the LAPC-I and the AWE64 is now working fine again. I guess I'll have to live without until I can figure out what going on here.

Does the LAPC-I work when the AWE cards aren't inserted?

Yes it works fine if the AWE64 is in or out, the problem is with the AWE64 not the LAPC-I

Did you try a DOS setup instead of 98SE?

No, I have not tried that yet actually, maybe I'll try that tomorrow

I have run the diagnostics app and it seems I have an I/O conflict I get the following error on addresses:

Error: Base I/O Address Setting

The diagnostics utility has detected that the current base I/O of your audio card cannot be used.

I have tried it on 220, 240, 260 & 280 (the only ones available) and get the same error on all of them. I only have one card in the PC at a time, so I don’t understand what it’s conflicting with.

You get this with just the AWE installed? What other cards or devices do you have installed?

Something I do to free resources is go into BIOS and disable the two COM ports and the Parallel port. Is the BIOS set to Plug and play? There is an option along the lines "PnP capable OS" or choosing resources automatically.

Things are getting odder, I think I'm going mad!

I have tried my setup in DOS 6.22 with the latest AWE64 DOS drivers installed etc, in DOS the LAPC-I does not work as expected, the sound in Monkey Island for example is totally messed up plays wrong instruments. The AWE64 however seems to work OK in DOS, do I have the opposite issue in DOS 🙁:(

I note that in DOS the MIDI port on the AWE and LAPC-I in the same 330 so I guess there is a conflict, I tried changing the port in my autoexec.bat file but upon restart is defaults back to 330 🙁:(

I note that there are jumpers on the LAPC-I that allows you to change the port to 330, 332, 334 or 336 do you think this is worth a try? it says that some DOS programs don't like this to be changed so I am in two mind whether to do it or not.

I am a bit confused about the whole BIOS changes to make on the ports, could someone explain that better to me?

The Monkey Island issue has probably to do with your PC being too fast. Disable L1/L2 caches and it should work.

I'd leave the LAPC-I at 330 because that's the port that a lot of games from that time default to, while with General MIDI supporting games you can usually change the port. For the AWE64 in DOS you need CTCM.EXE AFAIK, you can download the driver package from the Creative site. It should allow you to change the port and should also configure SET BLASTER accordingly.

About disabling the ports, it's pretty self explanatory. If you have no use for the serial or parallel ports it's usually a good idea to disable them in the BIOS. Read the manual for your motherboard or just look around in the BIOS to find the options for that.
