NOTE: In the normal boot process, shown in the preceding table, even though the BMC is
running while the system is shut down (power LED is steady amber), it doesn’t drive the external
health LED to steady green until +12 VDC power from the Bulk Power Supplies is applied.
The following list itemizes the steps that characterize basic platform boot flow. Step numbers
provided correspond to the steps in the preceding table, Table 5-31, “Normal Boot Process LED
States”:
3) System power switch turns on bulk power supplies and fans, and releases RESET on all CPUs
simultaneously, when toggled on.
5) Initial CPU firmware code fetch is PAL code from EEPROM in PDH, retrieved 4 bytes at a
time by DMDC in zx2 (No shared memory or I/O devices are available at this time; for example
they are not initially configured).
5) Firmware code stack is initially in BBRAM in PDH, retrieved 4 byes at a time, through PDH
and DMD buses.
5) PAL code configures all CPUs.
5) SAL code configures all platform zx2 chips, including shared memory and all responding I/O
devices.
5) Firmware code and stack are relocated to shared memory, after all x4 DIMM ranks in shared
memory are configured and tested.
5) EFI Shell is launched from shared memory, and cache lines are retrieved 128 bytes at a time
by MEMC in zx2.
6) OS loader is launched using the EFI device driver.
6) OS boots and starts its own device drivers.
6) OS may use runtime PAL and SAL calls, and APCI features (these abstraction layers allow
platform independence).
Firmware
The system has three sets of firmware installed:
• System firmware
• BMC firmware
• iLO 2 MP firmware
All firmware (SFW, BMC, iLO 2 MP, etc.) must be from the same release. Independent updates
are not supported. Details about a specific release are available in the associated Release Notes.
Firmware updates are available from http://www.hp.com under “Support and Drivers”.
