Boot Mode: Legacy BIOS or UEFI

AstLinux 1.4.5 or earlier only supports Legacy BIOS booting.

AstLinux's SSD has a FAT16 formatted 1st partition marked as bootable with a master boot record (MBR). Hardware Legacy BIOS will jump to syslinux installed on the FAT16 partition which in turn calls RUNNIX (minimal Linux kernel) also on the FAT16 partition, and lastly ``kexec`` the desired AstLinux run image.

AstLinux 1.4.6 or later supports both Legacy BIOS booting and UEFI booting. RUNNIX 0.6.10 or later is also required to boot with UEFI.
