In large-scale datacenter environments, traditional BIOS-based automation quickly becomes a bottleneck. This post explores how I automated server provisioning and RAID configuration directly through UEFI, without using a live OS. From building a bootable ISO with xorriso to embedding BOOTX64.EFI from EDK2, we’ll walk through each step — creating startup scripts, managing RAID controllers, and understanding UEFI’s limitations like missing log-transfer tools. This guide demonstrates how firmware-level automation can simplify provisioning across clusters while minimizing wasted storage and deployment overhead.
