Since CMSGEND renames the existing module, users who are currently
using the CMS system disk are unaffected by the regeneration procedure.
This is because the SSTAT (system status table) of the CMS system disk
is still pointing to the old (renamed) module. Whenever 190 is
subsequently IPLed, the SSTAT points to the updated modules, so that the
old module can be erased.
Loading a CiviS Nucieus
When you are ready to load the CMS nucleus, you should plan ahead for
two si tuat ions.
If you are going to test the CMS nucleus on a minidisk other than 190 (we are using 390 in this example), you may want to save the nucleus
reader file so that you do not have to repeat the VMFlOAD procedure if
the nucleus tests out all right. To do this, issue the command:
spool reader hold You may also want to issue the command
spool printer to *
so that the nucleus load map is routed to your card reader, instead of
the virtual printer.
If your CMS system uses the CMSSEG discontiguous saved segment, you
should anticipate that it may not be compatible with the new CMS nucleus. Later, you will want to use the CMSXGEN procedure to save the
segment, but for testing purposes, you do not need it. Therefore, to
prevent CMS from attempting to attach CMSSEG after IPL, you can define
your virtual storage to 2M: define storage 2m
Now you can issue the IPL command to load the CMS nucleus:
ipl clear
During the 1PL sequence, you must respond to the following messages. DMSINI606R SYSTEM DISK ADDRESS = cuu
Enter the device address (cuu) of the system disk (S-disk). This
is usually 190. On this disk CMS expects to find all CMS system
information and programs not contained within the CMS nucleus, such
as the disk-resident command modules. If the eMS nucleus is written
on this disk, then cuu is also the IPL device address.

April 1, 1981 Updating If you enter an invalid device address, the message DMSINI079E INVALID DEVICE ADDRESS - REENTER
is issued. Message DMSINI606R is reissued so that you can enter a
valid device address.
If you press the carrier return without entering a device address, X'190' is assumed to be system disk address. DMSINI615R Y-DISK ADDRESS = cuu
Enter the device address (cuu) of the system disk extension (Y-disk). On this disk CMS expects to find all system
information and programs not contained within the CMS nucleus and
not on the If the CMS nucleus is written on the Y-disk, then cuu is also the IPL device address.
If you enter an invalid device address, the message: DMSINI079E INVALID DEVICE ADDRESS - REENTER
is issued: Message DMSINI615R is reissued so that you can enter a
valid device address.
If you press the carrier return without entering a device address, X'19E' is assumed to be the address of the system disk extension. Notgl If you do not want to have a Y-disk, do not attach the device
that was specified (or defaulted to) as the Y-disk address. DMSINI607R REWRITE THE NUCLEUS? If you enter "yes", a copy of the CMS nucleus is written onto the
disk indicated in the response to messageDMSINI608R. If you enter
"no", the eMS nucleus is not written to disk.
If you enter neither "yes" nor "no," the message DHSINI081E INVALID REPLY - ANSWER "YES" OR "NO" is issued. Message DMSINI607R is reissued so that you can enter a
valid response.
If you enter "no", the remalnlng messages in generating a new CMS nucleus are skipped and control is passed to the CMS initialization
routine. DMSINI608F IPL DEVICE ADDRESS = cuu
Enter the address of the device (cuu) on which the CMS nucleus is
to be written. If you are using 390 to test the CMS nucleus, you
enter: 390. If the system disk and the IPL device are to be the
same, you need only press the carrier return.
If you enter an invalid device address, the message INVALID DEVICE ADDRESS - REENTER
is issued. Message DMSINI608R is reissued so that you can enter a
valid device address.
