IRQ Related

Recently I had a problem with my sound card (Creative Labs SoundBlaster PCI 128) and reinstalled it.  Sound is now back working fine.  

However, here is the new "condition".  My SCSI card does not load because the Sound Card has taken both IRQ numbers 10 and 5.  My SCSI does not show up at all anymore under Device Manager.  (It is a Adaptec 2940 UW)  

Any advice on what I need to do to remedy this.
TIA

Since the sound card is PCI you should be able to remove it from control panel and then shut down and move it to a different PCI slot.  This should change the configuration fo it and allow the SCSI to work agaiun.

Is the SCSI ISA or PCI?

Did you try using "add new hardware" from the control panel? and let it look for new devices

delcolleAuthor Commented:
I did try the "add new hardware" without success.

Since I returned the Sound Card to same PCI slot, did not touch the scsi card, I am unsure as to why to move it to another slot.  Your advise is appreciated.

Is there anything in Device manager that has a yellow "!" or a red "X"
Any unknown devices?

Do you have anything hooked to the SCSI card?

There are no showing "conflicts" under Device Mgr.  I have just a CD-RW associated with the SCSI card.  The SCSI is PCI.  (Adaptec 2940 UW)

My comment might sound stupid but you already said that:
"...My SCSI card does not load because the Sound Card has taken both  IRQ numbers 10 and 5......"
I guess you have found the problem. Cant you just remove one of IRQ ports either 5 or 10 and install your SCSI on it? You said it doese not show on device manager which means that it is not installed. You have already isolated the problem. Do you need help to delete a IRQ port or/and install SCSI ? That will be another question though.. but tell us if you can not do it and we will help.

NavidCommented:
You can not Add new hardware without any free and suitable ports. So your attempt on installing new hardware did not work, is very understandable.

Navid...

It appears that SoundBlaster "Legacy Device" is using IRQ 5.  However, when I run "msinfro32" it shows that IRQ#5 is "free".  So, I am at a loss.  I am not certain what is the next step.  Please advise.  Thanks.  (I will answer any questions you may have to resolve this.)

NavidCommented:
Instead of wasitng your time on trouble shoots, Remove devices from both Sound blaster and SCSI, then install SCSI first and then your soundblaster. In this way you can make sure that SCSI can be installed.
The easiest way to remove these devices, is using "Device manager" in System on Control Panel.(do it on windows safe mode. Recommended )
Then use "Add new hardware" to install SCSI first and then install sound blaster.
To be honest sound cards are usually very dominant and many conflicts and port errors accours when you install sound cards first before installing other hardwares..

I took your advice and under "safe mode" uninstalled both Sound and SCSI,  Then when I rebooted Windows automatically begin to process "New Hardware".  First "PCI Multimedia" (obviously SoundBlaster) and then "Unknown Device".

Now IRQ #5 is also associated with SoundBlaster (as is #10) without any signs of Adaptec SCSI.  SCSI does show in Device Mgr. in the safe mode.  

Again, I am stumped and at a loss.

Thanks

I'm not sure on this one, but I think
Sound Blaster has an option of changing it's
IRQ. Does your card have jumpers ?
Maybe you can get something out of the manual.
IRQ conflicts are awful. I thought they would
have solved the problem by now. Also, does'nt
WINDOWS have an option of IRQ sharing ?

Good Luck, Guy

try removing the sound card (from device manager) and phyically remove it from the computer, then boot up and install the SCSI card.
Then shutdown and replace the soundcard and boot up again and see if it installs correctly and the SCSI is still there.

rayt333Commented:
If above suggestion doesn't help then we may have to go into the CMOS setup (BIOS) and assign an IRQ to the slot the SCSI is installed in.

Asta CuTechnical consultant & graphic designCommented:
I'd do this.  I assume you do not need DOS only support, free up resources as follows:

start-run-msconfig-

Go to autoexec bath and UNCHECK (to disable) lines that say anything about:

set blaster, set CTsynth, and other entries with sb or sblive, or the like.

Reboot and reboot again, check device manager and advise.  Also start-run-msinfo32-hardware-problem devices and conflicts, advise.

You may also need to check and repair your ASPI layers, here's more on that:

Updating the ASPI Layer to the Most Current Version
 
ASPI (Advanced SCSI Programmer's Interface) is a layer of software which manages communication between all kinds of software and your peripheral devices. For CD recording software to function well with CD recorders (including ATAPI / IDE recorders!), it is important that the ASPI layer be up to date.

All Adaptec CD-R software for Windows installs the most recent version of ASPI for you as part of its overall installation process - unless you already have a more recent version installed. But ASPI can sometimes be overwritten or corrupted by the installation of other software or peripheral devices.

.... more here ..... as well as the aspichk and aspi32 fixes to download.

http://www.adaptec.com/worldwide/support/supporteditorial.html?prodkey=ASPI_Layer_Upkeep

Is your system and BIOS current, supporting PNP, set to PNP yes (plug and play operating system)?

More, if needed.

I had done just as you suggested when I had the sound card problem a few days ago.  (Removing physically, etc.)  It was after that when the SCSI card would be detected.   I am going to take a look a the BIOS but I am not too sure if I know just what to adjust.  If you have any advice, please offer.  Thank you.

Removed the check mark on 2 entries in the "Autoexec.bat" and rebooted twice.  Still no change and the "check mark" were back in place after reboot.  There are no conflicts when running msinfo32.  Infact, other than in the safe mode, the SCSI device does not appear.

Asta CuTechnical consultant & graphic designCommented:
I would access SAFE MODE, as you did above to do scanreg/fix, and check device manager, removing all unknown devices, ports, sound card related items, SCSI adapters, and reboot, having drivers and W98SE discs handy to reinstall drivers.  Others may have additional advice here.  If you have more than once SCSI device, you may also have scsi ID conflicts, since no two may be the same.  If you have a device conflict, which we suspect, we need to isolate the problem and remove all unknwon devices and multiples and problem items to allow Windows to reallocate resources.  If your BIOS is not set to PNP OS = yes, and needs a BIOS update, we may be chasing our tails here.  These comments assume all prior recommendations have been tested and failed to produce results.

Asta CuTechnical consultant & graphic designCommented:
When sound cards are "reinstalled", sometimes they leave an extra joy stick behind that hogs resources and causes problems, tough to detect.  Here's how to check that out:

Safe Mode again then - control panel - multimedia - expand all and remove duplicates and errors ... often erroneous joy sticks remain.

REboot, test.

Good luck and good night all.  ":0)  Asta

Have you tried starting the machine with the SCSI adapter but not the soundcard in place? Can you determine which IRQ is associated with it? If it's either 5 or 10, it might be an idea to try changing it. If this adapter has a BIOS of its own, it should be accessible during boot-up. Some Adaptec use <Ctrl>+A to get into their setup (it shows on the screen). If you don't use both IDE channels you may use IRQ 15, if one serial port is unused, you'll have 3 or 4 free etc.

to RID...

Your suggestion sounds good.  The soundcard is #10 and the SCSI has always been #5.  You are correct that <Ctrl A> is for setup  

Can you provide me with more detail on how and what to do when at the SCSI Bios?  (I thought that was if I had a SCSI harddrive.)

Thank you and all for your advise.

ridCommented:
If you can access SCSI host adapter BIOS (<Ctrl>+A), you can find a few options there. I don't have the same adapter as you  have, but I think they all have similar setup. I think there is something about Host Adapter Settings and choosing this option gets you to the next layer. Somewhere among the various options you'll probably get to choose IRQ line and perhaps I/O address. Don't bother with the SCSI units that are attached, the problem is with the host adapter. If you find the right screen, make your choice and back out with <Esc>, until you are prompted to save changes. The machine needs to be rebooted, but I think this comes automatically. To make a good choice of IRQ you need to know if there are any that are free to use. 5 is very popular among the sound cards and it is the most common choice for a second parallel port. 6 is the floppy drive, I think, 7 is LPT1, 3 and 4 are the serial ports. 12 is normally for PS/2 mouse. 10 and 11 are often free, 14 and 15 are for the IDE controllers. You can use Device Manager to see which are in use. Hope this helps...

have you tried to load the scsi drivers that came with the card. you should have gotten a diskette with that card. i have the same card in my system with a hp and a yahama cd writer and a hp scanner all connected to mine.

To access BIOS, the best way is to click on "Delete" key as soon as computer starts.(click on it right away as soon as computer starts)
But you should be able to install a SCSI  hardware using "new hardware" on windows.(if the old hardware is completely removed)
Using the BIOS is way too dramatic.
Anyways, come up with questions. You are in good hands. Many great experts are involved in this question.

Ultimately I removed both the SCSI and the Sound Card, reinstalled, and disabled "legacy device" option and now everything is a-ok.  I thank everyone for their suggestions.  I have learned considerable information from this very informed group of participants.  Thanks again.
