System Board Type A-1 (Aptiva 2134/76 - SL-A)

  System Board Type A-1 (Aptiva 2134/76 - SL-A)


The Type A-1 System Board supports the Pentium processor and has the following features:

•  P54C socket 7-ZIF connector. You must remove the old processor to  install an upgrade processor.
•  16 KB internal cache memory, and also supports up to 512 KB external  cache.
•  Shared frame buffer of 1 MB or 2 MB of video DRAM.
•  Shared frame buffer utilizes the Unified Memory Architecture which uses  the SIMM memory for both system and video. User selection of 1 MB  or 2 MB for video memory is available from the system setup.
•  Four, 72-pin system memory module sockets support these memory  modules:
  •  4 MB, 8 MB, 16 MB, or 32 MB SIMM modules.
  •  Parity (36 bit) or Non-Parity (32 bit) memory SIMMs.
  •  Memory speed of 60 nanoseconds (ns).
  •  Tin-lead contacts.
  •  Fast page mode or extended data out (EDO).
  •  Dynamic Random Access Memory (DRAM).
  
   Depending on model, 8 MB, 12 MB, or 16 MB of system memory is  supplied. Maximum system board memory is 128 MB. Refer to  'System Memory' and to 'SIMM Configurations - Type A-1' in System Board.
•  Ports: video, parallel, serial (two), keyboard, and mouse.
•  Connectors for:
  •  PCI/ISA riser card (2x106-pin)
  •  VESA Video Feature Bus (2x13 un-shrouded header). See 'VESA Local Bus Note' on page 1-6.
  •  Internal VGA display (2x7 shrouded header)
  •  Input power (12-pin)
  •  AT diskette drives (34-pin)
  •  Two 40-pin Enhanced IDE drive controllers: a primary local bus  IDE that supports two hard disk drives and a secondary Enhanced  IDE that supports a CD-ROM drive and one hard disk drive, or two  hard disk drives.
    Note:  Enhanced IDE for the Type A-1 system board supports up  to Mode 4. Mode 1, 2, 3, 4, etc. are the progressive industry levels  for Enhanced IDE.
  •  Power light-emitting diode (LED)/hard disk LED (4-pin)
•  Power-on switch 2-wire connector and a power supply auxiliary control  3-wire connector for Rapid Resume features.
•  Wake Up on Ring connector for Rapid Resume automatic wake-up features.
•  12 volt speaker power connector.
•  Lithium battery.
