Installing a Hard Disk Drive/CD-ROM

This section describes how to install IDE devices such as a hard disk drive
and a CD-ROM drive.
About IDE1 and IDE2 Devices
Your mainboard has a primary and secondary IDE channel interface (IDE1 and
IDE2). An IDE ribbon cable supporting two IDE devices is bundled with the main-
board.
If you want to install more than two IDE devices, get a second IDE cable and
you can add two more devices to the secondary IDE channel.
IDE devices have jumpers or switches that are used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user's manual. When installing two
IDE devices on one cable, ensure that one device is set to MASTER and the
other device is set to SLAVE. The documentation of your IDE device explains
how to do this.
About IDE3 and IDE4 Devices
The third and fourth IDE channels are provided for IDE RAID function. These
channels are booted by hard disk drive only. Other device such as CD-ROM
and ZIP does not support this function. For installing devices on IDE3 and
IDE4, follow the same procedures for IDE1 and IDE2 "Installing a Hard Disk
Drive".
About UltraDMA
This mainboard supports Ultra DMA 33/66/100/133. UDMA is a technology
that accelerates the performance of devices in the IDE channel. To maximize
performance, install IDE devices that support UDMA and use 80-pin IDE ca-
bles that support UDMA 33/66/100/133.
Note: If your mainboard incorporates the VT8233A Southbridge chipset, the Ul-
tra DMA bus mastering can support up to 133 MB/sec transfer rates.
Otherwise, the VT8233 Southbridge chipset can support up to 100M/sec
only.
