Hi,
it's the same with Backint/ADSM. To find out, use the file command:
# file back*
backagent:      PA-RISC1.1 shared executable dynamically linked -not
stripped
backfm:         PA-RISC1.1 shared executable dynamically linked
backint:        PA-RISC1.1 shared executable dynamically linked -not
stripped
brbackup:       ELF-64 executable object file - PA-RISC 2.0 (LP64)
if it's PA-RISC1.1, it's 32 Bit.
Bye, Stefan Wolf
