Worked on optimizing the IPXE build toolchain for amd64 within the jasperla/openbsd-wip repository, focusing on enhancing build efficiency and compatibility. Updated the Makefile to utilize the x86_64-elf toolchain, enabling more reliable cross-compilation for system programming tasks. This approach streamlined the build process and addressed compatibility concerns specific to the amd64 architecture. The work leveraged expertise in build system configuration and cross-compilation, with Makefile as the primary language. No major bugs were reported during this period, and all critical issues were either resolved or scheduled for future cycles, reflecting a focused and methodical engineering approach.
