Information Distribution Via ROM Disks

      This article describes a process for program and
documentation distribution via the FULL ROM and PARTIAL ROM function
of rewriteable disk media.

      The distribution of new software releases, program temporary
fixes (PTFs), microcode releases, microcode updates, and
documentation is a costly and time-consuming process.  This article
addresses this problem by providing a lower cost means of replicating
and distributing software, software PTFs, microcode, microcode ECs,
and documentation while at the same time controlling access to only
those users authorized to receive the information through the use of
a Read-Only- Media capability on 130 mm disks.

      The following elements were used to implement the process:
      1.  A FULL ROM or PARTIAL ROM DISK
      2.  On PARTIAL ROM disk, a rewriteable area that contains:
           a.  A customized system for the target user.
           b.  Target system CPU serial number.
           c.  The decryption keys for the authorized licensed
program products or documentation to be used to access the data in
the ROM area.
      3.  On PARTIAL ROM disk, a Read-Only-Media area that contains:
   a.  A Utility program to verify the target CPU serial number of
this distribution.
           b.  A Utility program to access the encrypted licensed
program products or documentation in the Read-Only-Media area,
decrypt the information using the keys, and load the decrypted
information onto a hard disk.
           c.  The encrypted licensed product programs, encrypted
licensed program product documentation, and the billable system
documentation.
      (For applications where all of the targets are receiving
identical copies of the distribution - no tailored configurations, or
options - the FULL ROM capability could be used.)
OPERATIONAL PROCESS:

      The following is one scenario in which the ROM capability could
be used to distribute program code and fixes, microcode and fixes,
and documentation.

      A PARTIAL ROM or FULL ROM disk is made that contains all
current program products with each program product having its own
unique encryption code.  The system and program product documentation
along with a unique encryption code is also placed on the disk.  A
stamper (the master for embossed disks) is made of this disk and a
quantity of ROM disks are made and placed in inventory.

      Upon receipt of an order from a customer, a PARTIAL ROM disk
from stock is initialized (the rewriteable area only) and the system
cod...
