IRQ assignments depend on OS? Tuesday, July 9, 2002 at 12:50 am Windows 98 Annoyances Discussion Forum Posted by Johan B (2 messages posted) Hi! I recently installed a US Robotics Network card on a dual-boot system (XP Pro, W98SE). Under XP, the card installed without a hitch - no hardware conflicts whatsoever. Under W98SE, I could not boot anymore. After disabling the network card in Safe Mode, my sound card was suddenly no longer operational - no free IRQ available! After inspection of the IRQ settings under both OS'es, I noticed one difference: LPT1 takes up IRQ5 under W98SE, and no IRQ under XP Pro... Removing the network card (physically!) returns my W98 to its previous operational condition. I have three questions: 1. How is it possible that a deactiviated device still modifies IRQ assignments? 2. Why does LPT1 require an IQ under W98SE, and not under XP Pro? 3. How can I fix my W98 setup? :-) All ideas and suggestions are deeply appreciated!
