A system and method for persisting device operating parameters through different phases of the boot process of a computer system. A boot command is entered to boot from a remote (or local) source through a boot device (e.g., a network interface, a disk controller), and is accompanied by one or more operating parameters (e.g., speed, duplex, link-clock). The parameters are converted to properties of the boot device and saved. Subsequently, one or more communication connections are established using the boot device properties. Using an initial boot program, the system may establish a first connection to access and load a secondary boot program, and another connection to load an operating system kernel. The boot device properties are thus used to establish communication connections at different times in the boot process, while the system is controlled by different programs (e.g., open boot PROM, secondary boot program, operating system kernel).
