About Dual Channel EIDE
The P5VPX97 has an integrated dual
channel EIDE controller; a primary and a
secondary. Each channel may support up
to 2 ATAPI EIDE devices, Hard Disk
Drives, CD-ROMs or other standard
ATAPI devices.
The primary channel has priority to the
secondary channel. Within each channel,
the two different devices are distinguished
by a master and slave relationship. The
master device has priority over the slave
device. E.G. If you are installing two
devices on a single channel, the master
will be assigned a higher drive letter than
the slave. (Refer to
Fig A.
on the right)
When installing a CD-ROM(s) with hard
disk drive(s), the hard disk drives will
have priority drive letter assignments over
the CD-ROM drives.
When installing more than one device per
channel, you must set one as a master
and the other as its slave device. These
device settings are usually determined by
a jumper that is on the ATAPI device.
