Dell Ins 5100 assigns IRQ to all devices

By Casemaker ·
Hi,
I am working on a Dell Inspiron 5100 notebook. The computer is assigning IRQ 10 to all devices. The video, NIC, modem, USB SM Controller, sound, IEE 1394 Host controller and the cardbus controller. Problem is only when I plug in the Linksys PCMCIA wireless card into the slot. The pc freezes. I looked in bios , limited options for me to change. I looked to change resources and everything is greyed out. I have done a complete reinstallation of os still the smae.

I suggest you boot into BIOS Setup screen and change PnP to manual and then set specific controllers to specific IRQs to spread them out rather than Windows doing it, this may solve the problem.

After you change the PnP to Manual you should then have the option of manually setting the IRQ's of the different devices, by default it will be on Auto but if you change this setting to Manual you will then find another layer of settings available to you where you can change the IRQ's from the defaults to what you want.

The BIOS main page lets me change time ,date quiet boot and video display device.
System Devices page has sticky Fn Function option only
Security page is basic password stuff
Boot lists 4 options for device priority
Then tha exit page.
It is very limited as you can see. No options for PnP or any onboard devices.

You could create another Hardware profile and disable some devices in it in device manager to allow you to use your PCMCIA device. The modem, 1394 and NIC are good candidates...

Woo that is very limited as options for any BIOS changes so much so as to be nearly useless to the average user.

Well as you can not alter the Auto Functions in the BIOS you'll could maybe go into Computer Management and manually alter some of the devices assigned to IRQ 10 to different resources that's if it's possible to do with that unit as by the sounds of it they have it as User Proof system as possible, Just Buy Dell products and You'll Be Right even thought they cost 20 times as much as what you can buy locally.

Lets know how you get on here and if you have any joy but this honestly sounds like a bigger version of Dell **** than I've ever seen previously.

Maybe it might be possible to change the PCMCIA slot to a different IRQ and DMA or maybe you'll just have to see if Dell offered a Wireless card as an option as they might not support this type of device.

Now I fully understand why I build my own NB's instead of relying on off the shelf units.

Is this still under warrenty? If so call about what is going on. Go into the bios and select load default settings or best settings for computer.
See if that helps, if not run the file and settings tranfer wizard to move the users stuff to a network share and reimage or reinstall. And see if that helps, if not there may be a hard ware problem.
