9 1. A READ IPL ccw is constructed in memory location ``0x0``.
15 2. Execute the Read IPL ccw at ``0x00``, thereby reading IPL1 data into ``0x00``.
17    information: ``[psw][read ccw][tic ccw]``. When the machine executes the Read
18    IPL ccw it read the 24-bytes of IPL1 to be read into memory starting at
19    location ``0x0``. Then the ccw program at ``0x08`` which consists of a read

56 management console. This "Load" procedure crafts a special "Read IPL" ccw in
59 written immediately after the special "Read IPL" ccw, the IPL1 channel program
60 will be executed immediately (the special read ccw has the chaining bit turned
71 1. Place a "Read IPL" ccw into memory location ``0x0`` with chaining bit on.
81 bit is on then the vfio-ccw kernel driver is allowed to read the entire channel
83 channel commands that read additional channel commands will not work as expected
84 because the newly read commands will only exist in guest memory and NOT within
87 the IPL process consists of transferring control from the "Read IPL" ccw
88 immediately to the IPL1 channel program that was read by "Read IPL".
104 1. Place "Read IPL" ccw into memory location ``0x0``, but turn off chaining bit.
105 2. Execute "Read IPL" at ``0x0``.
110    execute the READ and TIC ccws from IPL1.  Normally the seek is not required
112    to read the very next record which will be IPL2. But since we are not reading
124    that detects a READ immediately followed by a TIC and breaks the ccw chain
125    by turning off the chain bit in the READ ccw. When control is returned from
