The Digital Personal Workstation is a family of entry-level to mid-range workstation computers developed and manufactured by Digital Equipment Corporation (DEC). These workstations are based on the DEC Alpha and Intel Pentium Pro or Pentium II microprocessors. Members of this family could run the Digital UNIX, OpenVMS and Microsoft Windows NT operating systems.〔 〕 The i-Series, based on Pentium Pro, was introduced first, on 23 September 1996. == i-Series == The Digital Personal Workstation i-Series was based on the Intel Pentium Pro or Pentium II microprocessor and ran Windows NT. Models included the: 〔 〕 * 180i - 180 MHz Pentium Pro, introduced on 23 September 1996 * 200i - 200 MHz Pentium Pro, introduced on 23 September 1996 * 200i² - 200 MHz Pentium Pro, introduced on 23 September 1996 * 266i - 266 MHz Pentium II * 300i - 300 MHz Pentium II * 350i - 350 MHz Pentium II * 400i - 400 MHz Pentium II * 266i+ - 266 MHz Pentium II * 300i+ - 300 MHz Pentium II * 333i+ - 333 MHz Pentium II These workstations supported either one or two microprocessors and used standard Intel chipsets: Pentium Pro models used the Intel 440FX, Pentium II models suffixed with "i" used the Intel 440BX whereas ones suffixed with "i+" used the Intel 440LX. A superscript "2" suffix indicated a dual processor configuration. The i-Series has four DIMM slots on its main logic board and supported standard unbuffered or registered 100 MHz ECC SDRAM DIMMs. Using unbuffered memory, the i-Series could support 32 to 512 MB of memory, with registered memory, 64 MB to 1 GB was supported. Unbuffered and registered DIMMs could not be mixed in the same system. Unbuffered DIMMs had capacities of 32, 64 and 128 MB, whereas registered DIMMs had capacities of 64, 128 and 256 MB. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Digital Personal Workstation」の詳細全文を読む スポンサード リンク
