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 Table 62.
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 can 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, and so on.) 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”.
Identifying and Troubleshooting Firmware Problems
Erratic system operation, or the fact that the server might not boot successfully to the EFI Boot
Manager or to the EFI Shell, are symptoms of possible firmware problems.
