OpenVMS ALPCPU02_062 Alpha V6.1-1H1 - V6.2-1H1 CPU ROUTINES ECO Summary

 
NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for the CPU Routines on OpenVMS Alpha V6.1-1H1 
through V6.2-1H1.  This kit addresses the following problems: 

Problems addressed in the ALPCPU02_062 ECO Kit:

  o  When a device driver uses IOC$NODE_FUNCTION to disable a device
     interrupt in the IRQ range 8 to 15, keyboard interrupts are
     also disabled.  This problem is seen on systems with
     customer-written drivers.  Because of the higher overhead of
     IOC$NODE_FUNCTION, the recommended way to disable interrupts is
     at the device itself.  The part of the code affected is used by
     AlphaServer 1000 4/200, AlphaServer 400 4/233, EB64 and
     AlphaStation 600 5/266 platforms, but the problem has only been
     reported on Digital AlphaServer 1000 4/200 platforms.
 
  o  If a device's EISA configuration utility CFG file requests two
     or more IRQs, the device can crash an EISA_based system.  This
     problem can occur on Digital AlphaServer 2100 4/250,
     AlphaServer 8400 5/275, AlphaStation 600 5/266, Digital
     AlphaServer 1000 4/200 and DEC 2000-300 platforms.


Problems addressed in the ALPCPU01_062 ECO Kit:

  o  On AlphaStation 200, AlphaStation 400 4/233, and AlphaServer
     1000 4/200 CPUs, about one out of every ten SET TIME commands 
     will set the year or month incorrectly.  It appears that the  
     most common incorrect years are 2014 and 1758.

     This problem is corrected in OpenVMS Alpha V7.0.


INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted.  If the system is a member of a VMScluster, the 
entire cluster must be rebooted.
