computer. All EIDE hard-disk drives shipped with Dell workstation systems are SMART-compliant. • The system's basic input/output system (BIOS), which resides in flash memory and can be upgraded by diskette if required. • Plug and Play capability, which greatly simplifies the installation of expansion cards. Plug and Play support included in the system BIOS allows you to install Plug and Play expansion cards without setting jumpers or switches or performing other configuration tasks. The ISA Configuration Utility (ICU) allows you to configure existing ISA expansion cards for conflict-free operation. Also, because the system BIOS is stored in flash memory, it can be updated to support future enhancements to the Plug and Play standard. NOTE: The Windows NT operating system does not provide ISA Plug and Play support. Therefore, some ISA Plug and Play cards (such as modem, sound, and network cards) may not work with your Windows NT operating system unless you configure them manually. • Universal Serial Bus (USB) capability, which sim- plifies connection of peripheral devices such as mice, printers, and computer speakers. The USB connectors on your computer's back panel provide a single connection point for multiple USB-compliant devices. USB-compliant devices can also be connected and disconnected while the system is running. • A modular computer chassis with a minimum num- ber of screws for easy disassembly and improved serviceability. • A chassis designed for both horizontal and vertical use. For instructions on using the workstation in a vertical position, see "Using the Optional Floor Stand" found later in this chapter. • A high-speed, high-resolution PCI video card. (Doc- umentation from the video card manufacturer is included with your system.) The system board includes the following built-in features: • Three 32-bit PCI expansion slots and two shared PCI (32-bit)/ISA (16-bit) expansion slots on a riser board. • A diskette/tape drive interface, which supports a 3.5-inch diskette drive and, optionally, a second diskette drive or a tape drive. • Enhanced integrated drive electronics (EIDE) sup- port. The primary and secondary interface are both located on the PCI bus to provide faster data throughput. Each interface supports extremely highcapacity EIDE drives, as well as devices such as EIDE CD-ROM drives and EIDE tape drives. • Two high-performance serial ports and one bi- directional parallel port for connecting external devices. • A Personal System/2 (PS/2)-style keyboard port and a PS/2-compatible mouse port. • An integrated 10/100 megabit-per-second (Mbps) 3Com® PCI 3C905TX Ethernet network interface controller (NIC). The NIC is configured using software described in Chapter 5, "Using the Network Interface Controller." The following software is included with your Dell computer system: • Utilities that safeguard your system and enhance the operation of its hardware features; for example, the Autoshutdown service lets you perform an orderly shutdown with a single touch of the power button. For more information on these utilities, see Chapter 2, "Using the Software Support Utilities." • A standard set of video drivers for the Microsoft Windows NT 4.0 or Microsoft Windows 95 operating system installed on your system. NOTE: Some video cards support the Windows NT 4.0 operating system only. To change the resolution, check the documentation that came with your monitor to determine the resolutions and refresh rates supported by the monitor. Then check the documentation that came with your PCI video card for instructions on changing the resolution. • The System Setup program for quickly viewing and changing the system configuration information for your system. For more information on this program, see Chapter 3, "Using the System Setup Program." 1-2 Dell Workstation Midsize Systems User's Guide
