Boot Image Execution
Once a boot image is located on a device in the Boot List, the system
firmware code hands off control to the AIX Boot code.

• LED Code E105 for Normal Boot or
• E15B for Service Mode Boot.
The AIX Boot code indicates LED progress codes in the range from 05XX to
09XX.

6.6 Power-On Self-Test
Power On Self Test (POST) is the process by which the firmware tests those
areas of the hardware that are critical to its ability to carry out the boot
process. It is not intended to be all-inclusive or to be sophisticated by how it
communicates with the user. Diagnostics with these characteristics will
generally be provided as a service aid.The following power-on self tests are
performed by the firmware on PCI-based RS/6000 systems:

6.6.1 Processor POST
The firmware tests the processor very briefly. If there is a failure, the system
will stop, and the initial beep of the speaker will not be heard.
will stop, and the initial beep of the speaker will not be heard.
6.6.2 Memory DIMM and L2 Cache POST
The firmware RAM POST tests all the memory, it is done in segments. After
the initial short beep, if the system stops with the hard file indicator on solid,
this is the indication that no memory was found. If some memory is found,
then a working 2 KB continuous segment is sought. If the 2 KB segment
cannot be found, the system stops with the hard file indicator on solid.

The L2 cache is tested. If it fails, there will be a momentary indication when
