BIOS-Supported Enhanced IDE Features
The BIOS has several feature enhancements for IDE hard disk
drives and support for other ГОЕ devices.
,The original IDE implementation was limited to two hard disk
drives with relatively slower data transfer rates. While this solution
is simple and reliable, it has some limitations that have become more
significant as the performance level of other system components and
overall system performance have increased dramatically with the
advent of new microprocessor, expansion bus and operating system
technologies.
In response to these demands, the IDE specification has been
updated to increase its capabilities and provide improved perfor­
mance. Together these are referred to as 'Enhanced ГОЕ'. Enhanced
ГОЕ features comprise the following:
• Support for IDE hard disk drives larger than 528MB.
• Support for IDE devices other than hard disk drives, includ­
ing IDE Tape Backup and CD-ROM drives,
• Support for two IDE channels with two devices per charmel,
allowing the use of four IDE devices in one system.
• Support for faster data transfer rates, particularly with IDE
controllers that use a PCI local bus interface.
This mainboard supports the use of these features, which work
with the onboard PCI ГОЕ controller that includes two connectors
built onto the mainboard. With this controller you can use one or both
connectors to connect up to four ГОЕ devices to the system. If you
want to use the second ГОЕ channel, you must enable it in the Chip-
set Features Setup section of the BIOS Setup utility.
