- TITLE :IRQ Conflicts on Gateway 2000 Computers
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:

- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1

-
- When installing Windows NT on some Gateway 2000 computers, IRQ
- conflicts may arise because of the default settings for COM ports or
- modems. If you have a built-in modem is built-in, it is usually set up
- to use COM1 and IRQ 4. There are also two additional COM ports
- configured as On Board COMA and On Board COMB in your computer CMOS.
- If a modem is installed, On Board COMA will normally have the
- following settings by default:
-
- On board COMA: COM3
- COMA_IRQ: IRQ-5
-
- When installing other devices that use an IRQ, such as network cards
- or sound cards, you may encounter IRQ conflicts if those devices are
- configured to use IRQ 5.
-
- For example, the Gateway may also include a Sony CDU-31A CD-ROM drive
- which uses IRQ 5 under Windows NT. If you follow the guidelines for
- installing that device in Windows NT, the CD-ROM still may not work
- properly. The IRQ conflict can be avoided by changing the COMA_IRQ
- setting in the CMOS or by setting up the device to use a different
- IRQ. To adjust IRQ settings, press CTRL+ALT+ESC at a command prompt or
- during boot to access the CMOS setup (ESC+F1 may also work). COMA_IRQ can
- be set to 4, 5, 9,
- or Disabled.
