Variants
TNS/X
Executables for the x86-64 variant are usually identified as ELF 64-bit MSB executable, x86-64, version 1 (HP NonStop Kernel), dynamically linked, with debug_info, not stripped), by the file utility.
These systems are unique, in that that NonStop Kernel always runs in a big endian mode, despite the underlying CPU being little endian.
TNS/E
Executables for the Itanium variant are usually described as ELF 64-bit MSB IA-64, version 1 (HP NonStop Kernel), by the file utility.
These machines boot using EFI, and can boot from an El Torito-compliant ISO 9660 volume, such as the HPI Loader, and Halted States SVCS NS1000FWV1 Update 1 (542908-002) disc, that has been archived.
TNS/R
Executables for the MIPS variant are usually described as ELF 32-bit MSB MIPS, MIPS-I version 1 (SYSV)), by the file utility.
