    3636The TSAR boot_loader allocates - in each cluster containing a physical memory bank - six fixed size memory zones, to store various
    37 binary files or data structures. The two first zones are permanently allocated: The PRE_LOADER zone is only defined in cluster 0. The KERNEL_CODE zone containing the ''kcode'' and ''kdata'' sgments is directly used by the kernel when the boot_loader transfers control - in each cluster - to the kernel_init procedure. The BOOT_ICODE, ARCH_INFO, KERNEL_ELF, and BOOT_CODE zones are temporary: they are only used - in each cluster - by the boot-loader code, and the corresponding physical memory can be freely used and re-allocated by the local kernel instance.

The '''BOOT_CODE''', '''ARCH_INFO''', '''KERNEL_ELF''', and '''BOOT_STACK''' zones are temporary: they are only used - in each cluster - by the boot-loader code, and the corresponding physical memory can be freely used and re-allocated by the local kernel instance when it starts execution.
