1. A system comprising:
a first node coupled to a memory region storing data associated with a boot process, wherein the first node comprises a boot handler and a first node identifier;
a second node comprising a second node identifier associated with one or more nodes storing physical locations associated with a memory address; and
a functional unit comprising a processor and address management circuitry, the address management circuitry configured to:
receive a request from the processor, wherein the request comprises the memory address associated with the second node identifier and is associated with the boot process initialized at the processor;
determine that a bit stored at the address management circuitry has a first value indicating to associate the request with the first node identifier bypassing the second node; and
transmit the request with the first node identifier to the boot handler at the first node in response to determining the bit has the first value.
