Comment:

I'm using an old Pentium II computer with a Vibra 16 PnP sound card to run my old stuff. Under Windows 3.11, 95, 98 and NT the sound card works perfectly. The only problem I have is the IRQ. When I try to run DOS games, there is no sound at all or the sound works but the OPL3 FM synth does not play at all. The IRQ right now is 10 (too much) and I cannot change it to 5 or 7. I tried assigning the card IRQ through the BIOS, but it didn't help. It's strange because last yeaar I did the same thing with the same motherboard and it worked.

Is there any way I can change the IRQ to 5 or 7?

PCI 1: free
PCI 2: free
PCI 3: Intrel Ethernet card
PCI 4: free

Read you motherboard manual. There are two points to make here. First, each PCI slot on the motherboard defaults to a certain IRQ. Moving the card to the appropriate slot should allow you to get the needed IRQ assigned.

Second, many BIOSes have an option to assign resources for legusy devices. In the Windows environment this means that the IRQ will be assigned exclusively to the slot/hardware.

One of those two methods should help you.

It is possible that you couldn't assign the needed IRQ because something else is already using it.

Are you running the game in pure DOS, or a DOS session in Windows?

One other item. Your BIOS may have a selection called PnP aware OS. What that means is Windows will control the resources.

There may also be another selection in the BIOS that allows the resources to be redistributed. Look for Reset Configuration Data.

I tried moving the card to the second ISA slot but I still got the same results. I checked the motherboard resources under Windows '98 and found that all four IRQ's which are necessary for the sound card to run under DOS are used by other devices. IRQ 3 is used by COM 02, IRQ 5 is used by PCI slot 3 (I tried removing the ethernet card by nothing changed) and IRQ 7 and 9 are used by ACPI resources. I tried every BIOS option I could to change the resources settings, but nothing helped.

The motherboard BIOS doesn't have the option to assign resources for legacy devices.

I tried running DOS games in both DOS session and pure DOS modes and got the same results.

I tried using the PnP aware OS option in the BIOS. This time nothing changed but the computer stoped responding when I tried to run a DOS game. The IRQ settings remained the same. It is really strange because last year I did exactly the same changes on this motherboard BIOS and it worked perfectly.

I tried the sound card on an ASUS P5A motherboard and it worked even better than it used to work on the P2B-F before the BIOS settings messed up.

Remove the ethernet card completely and leave it out for now.

Insert the sound card in PCI 3. Reboot and enter the BIOS. Enable Reset configuration data for one boot cycle.

Check to see what IRQ is being used by the sound card. If OK, re-install the network card. You may need to play with resources for it too.

Did you look for the other options I mentioned in #1?

Yeah, the Vibra card won't work for DOS stuff unless it's on IRQ5. Probably IRQ7 would work, but not as well. When you removed the Ethernet card, what do you mean nothing changed? Wasn't IRQ5 free or available since it was no longer being assigned to the Ethernet card (since it wasn't there anymore)? Did you remove the Ethernet card by first removing it in device manager and then physically removing it from the machine? Because, maybe if you also remove the Vibra and then reinstall it with IRQ5 free and available, maybe it will be assigned IRQ5 since that is the default for that card. The reason it won't work in MS-DOS mode is because Windows sets it up using PnP to IRQ10 and it holds that setting as long as power is on. If you power off the machine and then just boot in DOS and SET BLASTER=A220 I5 D1 H5 P330 T6, then your DOS games will probably be able to use it. (I have a Vibra card in a Win98 machine and that is the default SET BLASTER settings the OS assigned after automatically detecting the card during OS installation, DOS games use it without problem running under Windows, or in MS-DOS mode).

When I removed the ethernet card the resources setting remained the same. I tried everything you said, but nothing helped. Everytime I tried setting the SET BLASTER command to SET BLASTER=A220 I5 D1 H5 P330 T6 it changed it into SET BLASTER=A220 I10 D1 H5 P300 T6 or SET BLASTER=A220 I12 D1 H5 P300 T6.

"When I removed the ethernet card the resources setting remained the same."

That is a little confusing to read. After the Ethernet card was physically removed from the machine, Windows continued to allocate an IRQ resource to it? I've never heard of Windows allocating resources to noexisting hardware.

You misunderstood what I meant about the SET BLASTER command. I only meant if you power on the computer and boot to a pure DOS environment. Windows set up the SET BLASTER command during initial device installation. It checks it each time it loads. It is programmed "repair" it to conform to the current resource allocations.

Just wondering, in Device Manager on this computer, when you look at the Computer Properties at the IRQ list, what does it show for IRQ5? It doesn't show something like "ACPI IRQ holder for PCI IRQ steering", does it? Does it show anything for IRQ5?

Do you mean something like Load BIOS defaults? Yes I tries both "Load BIOS defaults" and "Load setup defaults" options and still got the same problem.

No, I mean exactly the phrase I posted. If you don't have that option then how about Plug & Play aware OS? Disabling that will then allow the BIOS to configure the hardware.

After I removed the ethernet card I tried to change the sound card resources settings on the device manager by choosing the option to do it manually. I tried to configure it to work under "initial resources settings" 0000, 0002 and 0003 (I don't know exactly how it's called in English because I'm using a non-English version of Windows '98). The device manager said that there is a conflict because IRQ 5 is used by PCI slot 3, that's it. There was no information about any card installed in it.

I have 7 OSes installed on this computer. One of them is a pure MS-DOS 6.22 system. That is the OS I wish to use for DOS gaming.
I tried to change the SET BLASTER settings but it always change it back to the last settings.

About IRQ 5 the device manager says it is used by PCI slot 3 and about IRQ 7 IRQ 9 it says "ACPI IRQ holder for PCI IRQ steering".

I have already tried that and it didn't work. Last year I disabled the PnP aware OS option and assigned IRQ 5, DMA 1 and DMA 3 for ISA and it worked. Now it doesn't and I can't find out why.

hi
DJ still hacking away with the old vibra hehe 9 out of 10 for trying
some ancient history;
try Disabling the com port using irq5 (remap to irq 10 if your mouse is using it(in the bios) if not its free! reboot. does the games work??

manually set irq in config.sys + autoexec.bat for dos session.
are you specifying anything in config.sys or auto exec? the card doesnt set itself even though its pnp, old cards lied alot
these* or similar settings see below should be there, in win 95/98 or you could use a pif file you still had to edit the parameters for the dos session and usually a reboot. Later pnp sound blasters blew all this crap away by being real pnp , and the world was a better place.

finally try a DOS multi boot disk to run in proper dos does the game work or still defaulting to irq10?

* settings
config.sys
DEVICE=C:\VIBRA16\DRV\VIBRA16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5
DEVICE=C:\VIBRA16\DRV\CTMMSYS.SYS


or

devicehigh=c:\vibra16\drv\vibra16.sys /unit=0 /blaster=A:220 I:5 D:1 H:5
devicehigh=c:\vibra\drv\ctmmsys.sys
(note devicehigh if your using himemsys)

autoexec.bat
path=%path%;c:\vibra16 >(not sure about this line, experiment)
set sound=c:\vibra16
set blaster= A220 I5 D1 H5 P330 T6
set midi=synth:1 map:e
c:\vibra\diagnose /s
c:\vibra\mixerset /p /q


ive got a couple of orchids 3dfx's here if your a really into retro pc's lol Aciiiiid!

:D

Why did you change the settings then? You have to go to the "Chipset Features Setup" & configure the settings for the serial ports & parallell ports...if you don't use them, disable them to free up their IRQ's. Then go to the "PNP & PCI Setup" menu, set "PNP OS" to NO, then manually configure the settings.

Do NOT select "Load BIOS defaults" or "Load Setup defaults" because it will reset all you manual configurations.

I know it's looks funny that I'm trying to use an ancient historic sound card but I need this card to run DOS games and especially to run old music programs like Impulse Tracker to play and record my own old Goa-Trance music.

I succeeded to change the IRQ and DMA settings back to I5 D1 H5 in Windows only, without disabling the COM 2 port. Under DOS nothing changes. I have two pure DOS systems installed in this computer in both of them there is no sound at all.

I tried everything you wrote, but nothing helps. After I put those lines in the Config.sys file and rebooted in a 100% pure DOS system, it said there is and error recognizing the sound card and showed some Hebrew letters mixed with ascci characters. It's starnge because DOS does not support Hebrew texts unless it has a special Hebrew support TSR, which I have never installed.

I read in a Romanian forum that the intel iBX440 chipset has some problems running some PnP ISA cards. I think that is the problem. I used that card once on an ASUS P3V4X mobo which uses the VIA Appollo 133 chipset and it recognized it easilly but made a lot of annoying noise on the right channel (like Pak Pak Pak). Yesterday I tried using it on an ASUS P5A Motherboard which uses the ALI Aladdin chipset and it worked perfectly, even better than it used to work on my P2B-F bofore the BIOS settings messed up.

What 3Dfx cards do you have? I'm interested in the first Voodoo card (The original by 3Dfx or the first Diamond Monster 3D).

I tried any setteing I could in the "Chipset Features Setup" menu, turned off the PnP OS option and configured the settings for the ISA card manually in the "PNP & PCI Setup" menu, but still got no results.

Last year I had to change the battery so the computer loaded the BIOS defaults. Any DOS program that uses the sound card crashed, so I went to the BIOS PNP & PCI SETUP" menu, turned off the PnP OS option and configured the system to preserve IRQ 5 DMA 1 and DMA 5 for ISA and it worked perfectly. A few days ago the power source burnt out and after I changed it the computer had to load the BIOS defaults again. I reconfigured the PnP setting again with exactly the same settings but this time it didn't work.

Wow. I apologize if my previous post seemed a little glib about your problem. It's difficult sometimes to understand just what someone is experiencing with a strange hardware problem. Yours is a lot more complicated than it originally sounded. From reading all the posts, it sounds like (for some reason) the motherboard BIOS is assigning IRQ5 to the PCI slot 3. I say that because you report that Windows Device Manager shows IRQ5 being used by PCI slot 3, but PCI slot 3 is empty. I have never experienced or heard of Windows assigning resources to empty PCI slots. It just seems it has to be the BIOS which is reserving that IRQ for that PCI slot. I can offer no reason why, could only guess that it might have something to do with when the Ethernet card was originally set up in that slot. But, I believe that you are going to have to figure out how to get the BIOS to release IRQ5 from that PCI slot in order to get your Vibra working again.
And it doesn't look funny for someone trying to get a "historic" Creative Labs sound card working for using old DOS software. Nothing works better for playing old DOS games than a genuine SoundBlaster. While the Vibra isn't exactly a SoundBlaster, Creative Labs designed the circuitry to respond to the original SoundBlaster drivers. I've used some clones which work pretty good, but nothing else quite matches the capatability for old DOS games.

When the PSU burned out it may have damaged other components.

One thing you could try is to clear the CMOS and then reset all the values as needed.

The power supply actually exploded. It made a POP! sound and turned off. After changing the PSU I found out that the CMOS was completely messed up. The computer could not recognize more than one IDE drive. Sometimes it recognized only one CD-ROM drive and sometimes only one hard disk drive. Sometimes, when the main hard drive was the one it recognized and it booted, the computer stopped responding and on the screen it said something like "HDD IDE (0:1)Error. Press any key to restart.". After loading the BIOS setup defaults everything worked as before the PSU accident. I configured IRQ 5 and DMA cannels 1 and 5 for the ISA sound card. At the beginning it only played sound while the OPL3 FM synthesiezer didn't play music. Now it doesn't play any sound at all. The sound card is in perfect condition. I tried it on another motherboard and it worked perfectly.

You might also consider flashing the BIOS. Even if you already have the latest version get another copy of it.
