P/I-AP55T User’s Manual
Dual IDE Channel Support
With the onboard ГОЕ controller you can connect up to four ГОЕ
peripheral devices to your system. With Enhanced ГОЕ you can con­
nect two devices to each connector. All devices are categorized the
saíne way IDE hard disks have been in the past, with one device set
as the "Master'' device and the second as the "Slave" device. These
two charmels are called the "Primary" and the "Secondary" channel.
The Primary channel uses IRQ14, the Secondary, IRQ15. If you are
not using the Secondary channel, you can leave it disabled it in the
BIOS Setup utility. This will leave IRQ15 available for other use.
Faster Data Transfer
Enhanced ГОЕ includes a scheme to support a significant increase
in the rate of data transfer from the IDE device to the rest of the sys­
tem compared to the previous standard. One aspect of this scheme
is support for Mode 3 and 4 timing. If you use both the onboard con­
troller and hard disks that support it you can increase the data trans­
fer rate up to as much as 17MB per second.
Power Conservation
This mainboard incorporates power conservation technology
which you can set up in the BIOS Setup Utility in the Power Man­
agement Setup section. The features include hard disk and video
controls to reduce system power consumption. For more informa­
tion, see the section on Power Management Setup in Chapter 3.
