Changing Base I/O Address
If I/O address conflicts occur between the IDE CD-ROM interface card and other devices, you need to change the base I/O address of the IDE CD-ROM interface card or that of the conflicting device.
Change the default base I/O address of the IDE CD-ROM interface card only when another device absolutely requires the I/O addresses assigned to the interface card. If you change the I/O address of your card, you may also need to change the IRQ line. Refer to the section “Changing IRQ Line”.
To change the interface card’s base I/O address:
1.Switch off your system and all peripheral devices.
2.Remove your system’s cover and IDE CD-ROM interface card.
