Technical Information
The PowerMate®P2166M/P2200M Series desktop and minitower systems come standard
with an Intel®Pentium™ multimedia extension (MMX™) processor, a 3 1/2-inch,
1.44 megabyte (MB) diskette drive, 256 kilobyte (KB) secondary cache, 16 MB or 32 MB
of random access memory (RAM), and 2 MB of synchronous graphics random access
memory (SGRAM).
The PowerMate P2200M system has a 200-MHz MMX processor and only comes in
minitower configurations. PowerMate P2166M systems include either a 166-MHz or
200-MHz MMX processor and come in minitower and desktop configurations.
PowerMate P2166M/P2200M Series system configurations are listed in Table 1-1 and
Table 1-2.

Each system incorporates power management features and uses factory installed software to
enhance the hardware features. Systems come with the Windows®95 operating system pre-
installed (hot-loaded) on the hard disk.
The following paragraphs give an overview of the desktop and minitower systems.
Differences between systems are noted as they occur.

Technical Information 1-3
DESKTOP SYSTEM CHASSIS
The desktop chassis provides an enclosure for the system board, power supply, four
expansion slots, a five-connector PCI/ISA backboard, and four storage device slots. The
expansion slots include two 8-/16-bit ISA slots, one dedicated 32-bit PCI slot, and one
shared PCI/ISA (32-bit PCI or 8-/16-bit ISA) slot.
The four storage device slots accommodate up to three accessible devices and one internal
hard disk drive device. The accessible devices include the standard one-inch high 3 1/2-inch
1.44-MB diskette drive and up to two 1.6-inch high 5 1/4-inch storage devices. The non-
multimedia hard disk systems ship with an accessible 3 1/2-inch diskette drive and an
internal 3 1/2-inch hard disk drive, leaving two accessible 5 1/4-inch storage device slots
available for optional devices. The multimedia systems ship with an accessible 3 1/2-inch
diskette drive, an internal 3 1/2-inch hard disk drive, and an accessible 5 1/4-inch CD-ROM
reader, leaving one accessible 5 1/4-inch storage device slot available for an optional device.
Figure 1-1 shows front panel features and locations of the accessible storage devices in a
desktop system. Multimedia systems come with a CD-ROM reader installed in the top
accessible device slot.
