3. The CDROM drive should be connected to the host on an IDE
interface. Each interface on a system is defined by an I/O port
address and an IRQ number, the standard assignments being
- 0x170 and 14 for the primary interface and 0x1f0 and 15 for the
+ 0x1f0 and 14 for the primary interface and 0x170 and 15 for the
secondary interface. Each interface can control up to two devices,
where each device can be a hard drive, a CDROM drive, a floppy drive,
or a tape drive. The two devices on an interface are called `master'
- Double-check your hardware configuration to make sure that the IRQ
number of your IDE interface matches what the driver expects.
- (The usual assignments are 14 for the primary (0x170) interface
- and 15 for the secondary (0x1f0) interface.) Also be sure that
+ (The usual assignments are 14 for the primary (0x1f0) interface
+ and 15 for the secondary (0x170) interface.) Also be sure that
you don't have some other hardware which might be conflicting with
the IRQ you're using. Also check the BIOS setup for your system;
some have the ability to disable individual IRQ levels, and I've
