Yes, a.out static executables built under FreeBSD-2.2 will run under BSD/OS-3.x and -4.x at least. FreeBSD ELF executables won't work under BSD/OS, however, because along with the switch to ELF the system call mechanism was changed from "lcall 7,0" to the faster "int $0x80". BSD/OS doesn't support the latter, apparently. John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
