PS/2 - 76/77 S Model Configures SCSI HD As 6,1


The 9576 or 9577 system configures the harddisk with a SCSI ID of 6,1 instead of 6,0. A POST error of 1047000 107 may also occur.

Problem Isolation Aids:

  1. This tip applies only if the 9576 or 9577 is a Model xUx, xNx,or xTx.
  2. This tip applies only if the unit is a 9576s, or 9577s.


  1. The problem is caused by a failing SCSI adapter. The SCSI adapter, FRU P/N 71G3576, should be replaced.
  2. If the symptom remains, utilize normal problem determination procedures to isolate the failing FRU or application.
