1-2 Dell Precision 210 Desktop Systems User’s GuideDELL CONFIDENTIAL - Preliminary 8/17/98FILE LOCATION: S:\SYSTEMS\Aftershock\UG\9371D\9371dc10.fmá A secondary cache of 512 KB of static random-access memory (SRAM) inte-grated in the single-edge contact (SEC) cartridge. The secondary cache alsoprovides error checking and correction (ECC) capability.á Dual-processor capability. The system allows the installation of a second SEC car-tridge (operating at the same frequency as the installed microprocessor), whichcan be purchased as a kit from Dell. Dual processing improves performanceunder operating systems that support multiprocessing, such as Microsoft ® Win-dows NT ® 4.0. Microsoft Windows® 95 and Microsoft Windows 98 do notsupport dual processing.á A 16-bit, integrated Plug and Play Crystal CS4237B audio controller that is SoundBlaster Pro-compatible and that supports the Microsoft Windows Sound System.See Chapter 6, “Using the Integrated Audio Controller,” for details.á System memory that can be increased incrementally up to 512 megabytes (MB)using unbuffered synchronous dynamic random-access memory (SDRAM) dual in-linememory modules (DIMMs).The memory subsystem also provides ECC capability, which corrects all single-bitmemory errors and detects all multibit errors. See “Adding Memory” inChapter 8 for details on installing additional memory.á Self-Monitoring Analysis and Reporting Technology (SMART) support, whichwarns you at system start-up if the hard-disk drive has become unreliable. To takeadvantage of this technology, you must have a SMART-compliant hard-disk drivein the computer. All enhanced integrated drive electronics (EIDE) hard-disk drivesshipped with Dell Precision 210 systems are SMART-compliant.á The system’s basic input/output system (BIOS), which resides in flash memoryand can be upgraded remotely or by diskette if required.á Plug and Play capability, which greatly simplifies the installation of expansioncards. Plug and Play support included in the system BIOS allows you to install aPlug and Play expansion card without setting jumpers or switches or performingother configuration tasks. The ISA Configuration Utility (ICU) allows you to config-ure an existing ISA expansion card for conflict-free operation. Also, because thesystem BIOS is stored in flash memory, it can be updated to support futureenhancements to the Plug and Play standard.NOTE: The Windows NT operating system does not provide ISA Plug and Playsupport. Therefore, some ISA Plug and Play cards (such as modem, sound, andnetwork cards) may not work with your Windows NT operating system unlessyou configure them manually.á Wakeup On LAN capability, which, when enabled in the System Setup program,allows the system to be started up from a server management console. WakeupOn LAN capability also allows remote computer setup, BIOS upgrades, softwaredownloading and installation, file updates, and asset tracking after hours and onweekends when local area network (LAN) traffic is at a minimum.
