In this paper we describe Bare Metal Linux (BML), a cut-down version of Linuxt 2.6 that requires no firmware, has an in-memory root file system, and runs without a virtualization layer. We designed and implemented BML in order to accelerate the bring up of POWER5e-based systems. The use of BML allows testing and validation of the POWER5-based system to be conducted in parallel with the standard path, which involves the bring up of a hypervisor, the partition firmware, and the operating system.
