Dell XPS H266, XPS H233 manual System Features

System Features

In addition to the standard features found in a traditional PC, the Dell Dimension XPS H233 and XPS H266 systems include the following new and/or advanced features:

•An Intel Pentium II microprocessor with MMX technology, specifically designed to handle complex multimedia and communications software.

•Secondary cache of 512 KB of SRAM included within the SEC cartridge.

•Main memory consisting of 32 to 128 MB of high-speed EDO SIMMs.

•Error correction code (ECC) support built into the system board that corrects single-bit errors and detects all multiple-bit errors when parity SIMMs are installed.

•Three 32-bit PCI expansion-card slots and two 16-bit ISA expansion-card slots. One shared expansion-card slot can accept either a PCI or an ISA expansion card.

•Support for SCSI hard-disk drives and CD-ROM drives when a SCSI controller card is installed in an expansion-card slot.

•A high-speed, high-resolution PCI video controller card installed in an expansion-card slot, rather than an integrated video controller, to provide video flexibility for customers.

•A 16-bit integrated audio controller that provides sound functions com- patible with a Sound Blaster Pro expansion card.

•A MIDI/game port for connecting a MIDI device, joystick, game pad, or other game input device.

•An integrated high-performance serial port and a bidirectional parallel port.

•Two USB connectors, which can simplify connecting peripheral devices.

Most of these features are briefly described in this chapter. For a complete list of system features, see “Technical Specifications” found later in this chapter.

When following the procedures in this manual, assume that the locations or directions relative to the computer are as shown in Figure 1-1.
