Dear SCO Customer,

Support Level Supplement (SLS) PTF4015A, the SCO hostmibd Supplement, 
replaces incorrect MIB data currently included in some SCO UnixWare 
operating systems.  SLS PTF4015A provides a new hostmibd which include 
the following host resource MIB changes:

   hrNetworkTable, hrPrinterTable, and hrDiskStorageTable, have been 
   converted to sparse tables and now align correctly with hrDeviceTable.

   hrStorageRam now returns the correct 'size' and 'used 'values'.

   hrStorageTable hard disk and CD-ROM entries now return correct values.

   hrSystemInitialLoadDevice now returns the correct index into hrDeviceTable.

   Reporting size on the disk drive was changed from blocks to kbytes.

The release notes, displayed prior to installation, can be found in:

        /var/sadm/pkg/ptf4015/install/ptf4015.txt


SLS PTF4015A contains:

        /usr/sbin/hostmibd
