Apple-Reserved Partitions

Apple typically reserves 2048 bytes of NVRAM space for use by Macintosh firmware and system software, as shown in Table 12-1. Part of this allocation constitutes the 256 bytes of parameter RAM (PRAM) that all Macintosh computers have traditionally provided for use by Mac OS.

Card firmware and application software can access some of the Macintosh PRAM space by using the Macintosh Toolbox routines described in Inside Macintosh: Operating System Utilities.
