NOTE 4 Troubleshooting Your PC If There Is an IRQ Problem Installing a Sound Board If There Is an IRQ Problem Installing a Sound Board Problem Solution You have installed a sound board and you get a message telling you that there is no IRQ (Interrupt Request) available for the sound board. Check that you have followed the installation instructions provided with the sound board. If there is still a problem • Restart the PC and press F2 when F2 Setup is displayed. • Reserve an IRQ for the ISA sound board. You can reserve IRQ 5, IRQ 9, IRQ 10 or IRQ 11 for this purpose. To do this, go to the Plug and Play Setup submenu of the Advanced menu and then set the chosen IRQ to ISA. Also, set the Plug and Play Aware O/S item to NO. • Press the F3 key to save the changes and quit the Setup program. • Redo the Windows NT installation procedure for the sound board. Plug and Play operating systems such as Windows 95 should, in normal circumstances, be able to allocate the IRQs that are used according to the hardware installed in the PC. 72 English
