    AST RESEARCH, INC.        TECHNICAL BULLETIN # 1330           7-17-96

    TITLE: SCO OpenServer 5.0 Install NCR PCI SCSI

    SUMMARY

       Systems may report an error after SCO OpenServer installation.

       This issue applies to all AST systems with NCR PCI SCSI
       controllers, including the Manhattan P, V, and G and the
       Premmia GX.

    ISSUE

       After initial installation of SCO OpenServer version 5.0, AST
       systems may report the following error:

         "PANIC: HTFS: Fatal error reading inode block 2626 on HTFS
         dev hd (1/42)"

    BACKGROUND

       AST systems with an on-board NCR SCSI controller currently ship
       with a driver  (P/N 911283-314) that is designed for SCO UNIX
       version 3.2.4.2, or Open Desktop version 3.0.  This driver will not
       work with SCO OpenServer 5.0, resulting in the error message above.

    ACTION

       AST released an updated driver, version 1.08 (part number
       911283-319), which is compatible with OpenServer version 5.0,
       as well as backward compatible with Open Desktop version 3.0
       and UNIX version 3.2.4.2.
