Problem w/ CdRW

[digital_d_17]

Yes, I would reccomend that you remove the "V90+DSL" modem since you said you don't need it. That will free up IRQ 11 and allow you to use the CD-RW. One question that I do have is, why did you choose to go with a SCSI CD burner?

Hello,
I have a question about my CD Writer. The problem under DEVICE MANAGER says that
"This device is causing a resource conflict (CODE 15)."
Now when I click on the RESOURCE tab I see in the RESOURCE TYPE/SETTING box INTERRUPT REQUEST as the resource type and 09 as the setting. In the CONFILICTING DEVICE LIST box it reads:
"Interrupt Request 09 used by:
SCI IRQ used by ACPI bus"

When I click on change setting the EDIT INTERRUPT REQUEST window appears. In this window it reads:
"Enter the interrupt request you would like to set for this device.
You may either enter a specific value and the nearest valid value will be selected automatically, or you may select a value using the arrows.”
Then there is a value box that only shows values of 09, 10, 11, and 12. Underneath this value box is the CONFLICT INFORMATION box. It reads:
"The setting you have chosen conflicts with the following devices:"
And then it will tell me the device. These are the conflicts with the values the computer gives me.

09 SCI IRQ used by ACPI bus

10 ACPI IRQ Holder for PCI IRQ Steering
Texas Instruments OHCI-Lynx 1394 Host
Controller

11 ACPI IRQ Holder for PCI IRQ Steering
Lucent V90+DSL Modem

12 WheelMouse (PS/2)

If I try to put in a value (any value from 0 to 15) it will tell me it’s not a valid value. Unless I put in one of the ones above (09,10,11,12) then it tells me those are conflicting.

I was re-reading the directions for the installation of the CD Writer and I found something that might come to use. The directions read:
"If the CD SpeedWriter Plus SE is the last device in the SCSI chain, set the terminator to on.

If necessary, change the CD SpeedWriter Plus SE SCSI ID number (to avoid conflicts with other devices) using the SCSI jumper son the back of the model. The default SCSI is six (6)."

The jumpers are in this position:

= = : = = :
(The the equals signs represent where the jumpers are located)

I had drawn a diagram that was on the top of the cdrw in msword but it won't let me copy it on here.
Now here is the question. Do I need to move the jumpers around? Or, should I remove one of the devices from above to make room for the CD Burner??? Maybe I could take away the value
11 ACPI IRQ Holder for PCI IRQ Steering
Lucent V90+DSL Modem

I’m using the Ethernet line here at my apartment and I will probably most likely be using an Ethernet line for next 4 or more years so I do not think I really need this device till later.

Well, I hope this email was not to confusing. I appreciate any help. Thanks

If you need any more additional information to help me, let me know.

Hey, I removed the modem device (Value: 11). I went back to change the setting for the Burner to Value: 11 but now it says that value 11 is being used by

ACPI IRQ Holder for PCI IRQ Steering
S3 Inc. Savage4 GT 8MB BitFLip Engineering.

I don't know what that is so i don't know if i should take it off. The reason why i chose the SCSI???? Well, it sort of a long story, so i'll make it short. I recieved a burner for my birthday almost a whole year ago. My computer would never recognize the burner, so my uncle suggested we get a SCSI. I don't remeber why. But anyway, my computer is not recognizing this burner and it sucks having a burner sitting in your computer not working. well...hoping for some good ideas that work. Thanks.

Honda.... I'm betting the reason this computer isn't recognizing your burner is because it isn't properly recognizing and loading the SCSI card/driver.

You didn't list what motherboard you have, but many have specific IRQ and Busmaster sharing limitations that you need to be aware of.

If you could list both your motherboard manufacturer and model number, as well as those for your SCSI card and CD burner, it would help us to troubleshoot your issue.

In the mean time, if you want, this is what I would suggest:

(1) Take out your 56k modem. If you are not using it, there is no reason to have it in the system anyway. Lots of reasons I suggest this, but for brevitiy, will not go into them right now.

(2) Move your SCSI card to another PCI slot. Some PCI slots on motherboards will not support busmastering or IRQ sharing, and some expansion cards do not either. If you happen to have placed your SCSI card into a slot that its not compatible with, the Operating system will have trouble assigning or sharing IRQ's with it and the other devices in your system, and you will end up with an issue like you describe.

As for setting termination on the last device in a SCSI chain, thats just part of the SCSI standards and rules. Since a SCSI chain can accept multiple attached devices, the only way for the SCSI controller to know which is the last device on the chain is with termination. Forget to terminate the last device in your chain, or terminate the wrong device (like one in the middle) and it will not operate properly......or at least all your devices won't.

There are other areas you need to be aware of as well when it comes to SCSI.... Like unique device ID's, SCSI controller termination, SCSI bios setups, and so on that we may need to get into later if what I listed above does not solve your issue. But in the mean time, give those a shot as I think that is most likely the cause of your issue.

You can also free irq's by disabling unused serial ports. What has worked for me is to free an irq, then remove all conflicting hardware from devive manager, then re-boot and let windows re-assign the irq's.
