SCSI Problem! HELP ME PLEASE!!

Hi, I've a big problema with my SCSI card and My new PC.
The SCSI is a Tekram DC-315U.When i bought it a installed it into my old PC (a PII 266Mhz with a QDI LEGEND V MotherBoard) with NO PROBLEMS!!!. Now I've a P4 1400 Mhz with an ASUS P4T Socket 423 INTEL 850 Chipset Motherboard and when i install the SCSI card the bios see it but all Windows OS (98,ME,2000) cause resource conflict not assigning it an IRQ so it goes to IRQ 00 even if they see the card!! (in Device manager the card appears with an esclamation mark):I've tried to change slot, to disable PnP in BIOS, to force an IRQ from BIOS but nothing!! When Windows find it it always change its configuration assigning IRQ 00.
So i tryed to force an IRQ from Windows Device Manager but it says to me that configuration can not be changed even if I uncheck the chekbox to modify it in the secition Resource of Device Managewr.
I can't use my pc from days and I've big job problems.Please HELP ME!!.I istalled times and times all my OS and my SCSI card but nothing!! Why????I had no problem with the old pc!!!Is QDI Legend V motherbord better???
All what I can see in that at the boot of the machine Video card has IRQ 11 and the SCSI IRQ 9 while PC Soun Card IRQ 10.
May be those information can help you to solve my big problems!!!
PLEASE PLEASE!!
What can I do?

Hey...I had a scsi card installation problem with win2000 as well...was using it for a iomega zip drive...had to take the card out and manually set the jumper pins to an unused irq...was fairly easy to do...um...not sure what you are trying to use the scsi for but I can give you instructions on how to manually check your pc and manually set jumper settings, if this is applicable.

For now I use SCSI for CD-RW device, a Yamaha. Settting the card IRQ with a jumper? And how? If you can explain me i can trie to do it even if i wonder why in the old pc with windowMe first and windowsME then it worked without any problem.
Plese tell me how can config the IRQ with a jumper
Thanks

I know what you mean...my scsi worked just fine in 95 and 98...detected automatically...but not for 2000. Since you have web capabilities, go to www.iomega.com/support/documents/10574.html
and follow those instructions to the letter. Really easy to do and pretty fast to accomplish. Print out the instructions if you can...only three pages long....hope this helps! Again...if this will apply to your situation.

Thanks Ryno, but my problem is another one.Ofter prblem with Win2k I installed win98 and then WinMe but it seems tha PnP does not configure the new hardware retrieved correctly.It doesn't reverve them resource (IRQ, I/O).After lot of try i'am able to use my scsi card but only after change configuration each time i start windows. So now i add my sound card but I have the same problem with it. I can't understand why PnP does no recognise resource for new hardware.I need pc to work and i've benn trying to make it run korrectly for 3 days!! If you o anybody elsecan help me i appreciate.
Thanks

Not sure if I can help but I had something similar happen to me

I had an adaptec 2094 pci scsi card it worked fine on a IBM 365 pc in win98 but took it to win2k and all my resources for the card were way out of sync. Win2k said I was using IRQ 20 something ???

Had my stumped for days, I tried all sorts of things until I removed all the cards in the pc except video started up win2k then added the cards back and belive it or not win2k sorted out it's resources problem. Ive never belived in PnP, sometimes I think no one will ever fully understand pc's

Hope this can help

Hi, I've already tried to remove all my cards and re-adding them one to one starting from the SCSI adapter but it had no effect in Win98/ME. Unfortunatly Win2k does not recognize my SCSI adapter (no driver found) so i can't use it.(if i try to load a driver downloaded from the web win2k crashes). I think the problem is like a conflict between the PnP of BIOS and the other one of Win OS. I'm not sure but i think this is the cause. I've tried to disable BIOS PnP OS option but nothing change. Any other idea? I appreciate all help. I'ven't been able to use my pc for days and i have to work sighhh!!!

THANKS

maybe you should try to download the drivers for win2k? Maybe servicepack 2 will fix your problems? Update your the drivers for your motherboard?

Thank you jmongstad, but the motherboard is the latest of the ASUS (it's for P4 CPU).I also tried to download the driver for win2K but when I install it the OS say to me that it is not Microsoft certified.I install it and win2k crash irrimediabily!!! (I had to format disk C and reistall a new OS - i choose win98 SE for the moment...).I don't know what else I can do...
Any idea is appreciate.
THANK!
