How can I change the IRQ for devices?

[Sauce]

When I boot the system, once windows (98) starts to load, the monitor goes black (sleep mode, because the power light on the monitor flashes green/orange)and stays that way, even though the hard drive is still working (apparently to finish loading windows). I have noticed that both the serial bus controller and the display controller are set on IRQ 12.  Is there a way that I can change the IRQ from the DOS prompt?

Sometimes you can goto Control Pannel -&gt; system -&gt; Device manager -&gt; properties after right clicking the device, should be on one of the tabs, you can sometimes manually set addresses, and sometimes you can share the IRQ, with a Printer<br> <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href=

serial bus controllers, I believe are the serial ports? In order to change the IRQ of these you would need to go into the bios. I can't recall what they should be offhand, but a search of the internet should take care of that.<br><br><br>fenris

If they're plug-n-play you might want to start in<br>safe mode (f5) then go to device manager and delete<br>any devices that have a conflict.It should show a yellow<br>exclamation point if there is a resource conflict. Restart and <br>see if windows puts them in they're proper place.<br>The monitor problem seems like it could be a setting<br>in bios???. Maybe some changes in power management.

IRQs, DMAs, and I/O addresses (often called system resources) are assigned to individual components in your PC. They control the orderly flow of data between each component and your PC. And if any two components share the same resource - say, both your modem and your mouse are set to IRQ3 - digital chaos ensues and your system crashes.<br><br>Fortunately, Windows9x, the PCI bus and the Plug and Play technology combine to do a pretty good job of assigning these resources each time your computer boots. In Windows 98, resource conflicts are listed under &quot;Hardware Resource - Conflicts/Sharing&quot; in the System Information utility. In Windows 95, you have to look for conflicts in the Device Manager. In either case if a conflict exists, you must fix it in &quot;Device Manager&quot;&nbsp;&nbsp;(go to Control Panel&gt; System&gt; Device Manager.<br><br>Suppose you have two non-Plug and Play cards - a sound card and a network card - that are both set to IRQ5. Let's also suppose your documentation says the network card can be reset to IRQ7, usually by setting a jumper or DIP switch on the card. Then you must reserve both IRQ5 and IRQ7 so Windows won't assign them to other devices. Do this by double-clicking the Device Manager &quot;Computer&quot; Icon and selecting the &quot;Reserve Resources&quot; tab. If Windows recognizes both cards and their settings, you're done. If not, you'll have to double-click each card's entry in Device Manager, go to &quot;Resources&quot; tab, and force each card to accept the IRQ of your choice by deselecting &quot;Use automatic settings&quot;.<br><br>I do hope this will help.<br>Charles Keller, Kelowna, BC, Canada - June 20, 2000..

Turn the USB off in the BIOS until you solve your dilemma. I don't think this is your problem however although the display should not be using 12- this is usually reserved for PS2 functionality. <p>Al<br><a href=mailto: atc-computing@home.com> atc-computing@home.com</a><br><a href= > </a><br>
