I
The specific function of the deadstart program during
coldstart from a tape unit is as follows:
• Identifies the channel and unit number of the tape
unit on which the controlware tape is mounted and
to be read.
• Reads the controlware tape which loads the tape
controller.
The tape unit and the channel used to access the unit are
identified by setting the switches shown in the unshaded
area of the deadstart panel illustrated in figure 2-4. The
tape unit number must be between 10 and 17 and the unit
must be on a channel withouta PP (for example, channel 12
or 13). Refer to appendix H to determine the channels
without a PP at your site.

The numbers are entered in binary form; each switch
represents one' bit in a 12-bit PP instruction word. The
remainder of the panel is not used.
Unloading of the controlware tape indicates that the

. Disk Controller from Card Reader
The specific function of the deadstart program during
coldstart from a card reader is as follows:
•
Identifies the controller and channel number used
to access the card reader from which the
control ware is to be read. Also specifies the
controller, channel, and unit number of the drive
on which the deadstart disk is mounted.
o Reads the control ware card deck. The function of
0
this deck is to load the disk controller. Processing
U
of the deadstart tape according to the options
specified on the deadstart panel is then initiated.
The equipment necessary for the devices used during
coldstart is identified by setting the switches shown in the
unshaded area of the deads'tart panel illustrated in figure
2-5. This includes the channel number and controller
associated with the card reader and the channel, controller,
and unit number of the disk unit.
The drive on which the deadstart disk is mounted and the
card reader must be on different channels. The card reader
must be on a channel without a PP (for example, channel 12
or 13). Refer to appendix H to determine the channels
without a PP at your site.
