Selective firmware placement during initialization of compute systems

A computer program product for initializing a compute system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable and/or executable by a processor to cause the processor to:

• in response to basic input/output system (BIOS) code being executed directly from flash memory, cause, by the processor, a cache to be initialized in a central processing unit (CPU) of the compute system;
• cause, by the processor, a communication path to be initialized, the communication path extending between the CPU and memory corresponding to a baseboard management controller (BMC) of the compute system;
• cause, by the processor, BIOS firmware to be copied from the BMC memory to the CPU cache;
• cause, by the processor, the BIOS firmware to be initiated from the CPU cache;
• causing a memory controller of the CPU to be initialized;
• cause, by the processor, a portion of the BIOS firmware to be copied from the CPU cache to memory corresponding to the CPU;
• and
• cause, by the processor, the portion of the BIOS firmware to be initiated from the CPU memory.

A compute system, comprising:

• flash memory;
• a central processing unit (CPU);
• a baseboard management controller (BMC);
• a processor;
• and
• logic integrated with and/or executable by the processor, the logic being configured to:
• in response to basic input/output system (BIOS) code being executed directly from the flash memory, cause, by the processor, a cache to be initialized in the CPU;
• cause, by the processor, a communication path to be initialized, the communication path extending between the CPU and memory corresponding to the BMC;
• cause, by the processor, BIOS firmware to be copied from the BMC memory to the CPU cache;
• cause, by the processor, the BIOS firmware to be initiated from the CPU cache;
• causing a memory controller of the CPU to be initialized;
• cause, by the processor, a portion of the BIOS firmware to be copied from the CPU cache to memory corresponding to the CPU;
• and
• cause, by the processor, the portion of the BIOS firmware to be initiated from the CPU memory.
