Dell Precision 610 mini tower systems have eight drive bays for installing the
following types of drives (see Figure 1-5):
‡
The externally accessible drive bays at the front of the computer consist of
one 3.5-inch drive bay (dedicated to a 3.5-inch slimline diskette drive) and
three 5.25-inch drive bays that can hold up to three half-height, 5.25-inch
devices—typically tape drives or CD-ROM drives. Alternately, 3.5-inch
devices can be installed in the 5.25-inch bays using adapters available from
Dell.
‡
The four-bay hard-disk drive cage below the externally accessible bays can
hold up to four 1-inch or up to two 1-inch and two 1.6-inch hard-disk drives
installed vertically. The maximum number of hard-disk drives must be
either two EIDE hard-disk drives or up to four SCSI hard-disk drives.
NOTE: For detailed information about installing SCSI devices, see Chapter 10,
“Installing Drives,” in the User’s Guide.

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) provides support for 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 provides support for up to two high-
performance EIDE devices, typically EIDE tape drives or CD-ROM drives.
