This section explains how to install expansion bay options such as internal hard disk, magneto-optic
disk drive, CD-ROM drive, and floppy disk drive. The power can be supplied from the PC main unit to
the expansion bay options, differing from external-type devices; therefore, an outlet is not required.
This is also useful in saving space.
Point
- To install expansion bay options, set up the PC, turn off the power, and then install the options.
- The internal hard disk supporting Ultra DMA/66 can be used by setting it to Ultra DMA/66.
To connect a hard disk not supported by Ultra DMA/33, be sure to set the DMA to OFF. If the PC
is used while the DMA is set to ON by mistake, it may malfunction and data may be lost.
Consult with the user's guide that comes with the hard disk, to check whether the additional
hard disk supports Ultra DMA/33.
- On the secondary IDE side, Ultra DMA/33 is not supported.
- Use the CD-ROM drive, equipped as a standard feature, without modifying its connection to the
secondary IDE. To add a hard disk or magneto-optic disk drive to the secondary IDE, reconnect
the hard disk or magneto-optic disk drive to the master connector and reconnect the CD-ROM
to the slave connector.
