This microcode update is version 1.29 for the RS/6000 40P Model 7020. Note that this microcode cannot be used on any other RS/6000 systems. The enhancement in this release is:
Year 2000 Support -- When the system time rolls over from 1999 to 2000, the operating system will understand the correct date*.
You will want to update your microcode if you need your system to behave properly when the year rolls over to 2000.
If the version of your current microcode is greater than or equal to 1.29, there is no need to upgrade your microcode.
* Please consult the IBM Year 2000 web page at http://www.ibm.com/IBM/year2000 for IBM's definition of "Year 2000 ready" and the latest information of the status of IBM products and the Year 2000.
