Subject:    -9- What is the IP number of each SGI model?
Date: 13 May 1994 00:00:01 EST

  There are two different IP numbers, one referring to the hardware and
  one to the software (kernel configuration). The latter is what you
  see when you type 'hinv'. Here is a table of both numbers:

  HW IP   SW IP   Model                  CPU     Speed
  -----   -----   --------------------   -----   -----------
  IP2     IP2     IRIS 3000              68020
  IP4     IP4     4D/50, 4D/70           R2000   12.5MHz
  IP4.5   IP4.5   4D/80, 4D/85           R2000   16MHz
                  4D/60                  R2300
  IP5     IP5     4D/1x0                 R3000   16.7MHz
  IP6     IP6     4D/20                  R3000   12.5MHz
  IP10    IP6     4D/25                  R3000   20MHz
  IP7     IP7     4D/2x0                 R3000   25MHz
  IP9     IP9     4D/210                 R3000   25MHz
  IP13    IP7     4D/3x0                 R3000   33MHz
  IP15    IP7     4D/4x0                 R3000   40MHz
  IP12    IP12    4D/30, 4D/35, Indigo   R3000   30-36MHz
  IP17    IP17    Crimson                R4x00   50 or 75MHz
  IP19    IP19    Onyx, Challenge        R4x00   50 or 75MHz
  IP20    IP20    Indigo R4000           R4x00   50 or 75MHz
  IP22    IP22    Indigo2                R4x00   50 or 75MHz
  IP24    IP22    Indy                   R4x00   50 or 75MHz

  The missing numbers were used for machines that were not released.
  R4x00 machines can be 50 MHz R4000s or 75Mhz R4400s. 'hinv' reports
  twice that in recent versions of IRIX; see the previous question for
  an explanation. We use the smaller number here for consistency.
