Hard-Disk Drive Options - Dell Precision 410 Service Manual

1-10 Dell Precision 410 Systems Service Manual
The enhanced dual-interface EIDE subsystem supports two EIDE interfaces
(primary and secondary), each of which can support up to two EIDE devices.
The EIDE controller resides on the high-speed PCI bus.
The primary EIDE interface (IDE1) supports up to two high-performance EIDE
devices. The computer's boot drive should be connected to the primary EIDE
interface.
The secondary EIDE interface (IDE2) also supports up to two high-
performance EIDE devices, typically EIDE tape drives or CD-ROM drives.
NOTE: The externally accessible drive bays at the front of the computer are
normally used for diskette drives, CD-ROM drives, and/or tape drives.
Hard-disk drives should be installed in the internal hard-disk drive positions
described in "Hard-Disk Drive Options" found earlier in this chapter. For detailed
information about the data storage subsystem, see Chapter 10, "Installing Drives,"
in the User's Guide .
SCSI drives are supported by using two integrated SCSI channels:
The primary (Adaptec AIC-7890) channel provides Ultra2/Wide LVD
(80-MB/sec) support for high-performance SCSI hard-disk drives and an
optional RAID subsystem.
NOTE: To achieve 80-MB/sec support, all of the installed SCSI devices
must support the Ultra2 specification's 80-MB/sec transfer rate. If they do
not, the transfer rate will default to the speed of the slowest device in the
SCSI chain.
The secondary (Adaptec AIC-7880) channel provides internal Ultra/Narrow
and external Ultra/Wide (40-MB/sec) support for SCSI CD-ROM and tape
drives, optical drives, scanners, and so forth.
The system board has an onboard 16-bit Plug and Play Crystal 3D CS4237B
audio controller chip and connectors on the back panel for connecting the com-
puter to external audio devices such as speakers/headphones and microphone.
The controller supports all sound functions contained on the Sound Blaster Pro
expansion card from Creative Laboratories, Inc.
Chapter 6, "Using the Integrated Audio Controller," in the User's Guide pro-
vides instructions for connecting the computer to external audio devices and
configuring the integrated audio controller to avoid resource conflicts.
