AST RESEARCH, INC.        TECHNICAL BULLETIN # 1716          05/13/97 
 
 
 
TITLE:  High Temperature Alert in DPT Event Log
 
 
ISSUE 
 
   The DPT PM3224 SCSI Controller may report High Temperature Alerts 
   in the DPT Event Log while the system is operating within the 
   tolerances of the Ambient Temperature specification.
   
   This issue applies to the following systems: 501502, 501503, 
   501830, 501832, and 503076.    

 
BACKGROUND 
 
   The threshold setting for the temperature logic on the DPT PM3224 
   controller has been set too low.    

 
ACTION 
 
   To resolve the issue, upgrade the BIOS and firmware on the DPT 
   controller to v3.DS/7H7.
   
   WARNING: AST highly recommends that all system drives be 
   backed-up prior to upgrading the DPT BIOS and firmware. 
   
   The BIOS and firmware on the PM3224 are not "flashable"; 
   therefore, you must replace the EPROM.
   
   Contact an AST Authorized Service Center and request a 
   replacement DPT SCSI Controller with BIOS v3.DS and firmware 
   v7H7.
   
   Replacement P/Ns:
   
   234067-004 for system P/Ns 501830, 501503, 501502.
   
   234440-005 for system P/Ns 501832, 503076.
   
   NOTE: DPT BIOS v3.DS requires a newer version of the DPTDDL.SYS 
   driver for DOS. Storage Manager v1.kn contains the new DPTDDL.SYS 
   driver for BIOS v3.DS. This driver is contained in the following 
   files:
   
      12794037.EXE
      12794038.EXE
      12794039.EXE
      12794310.EXE

      To decompress this file, create a temporary directory 
      on your hard drive, copy the downloaded file to that 
      directory, and run the file. 
   
   
   AST recommends that all DPT SCSI drivers be updated after 
   upgrading the DPT BIOS and firmware, regardless of operating 
   system used.
