Pete, We had a problem in user-space apps all showing 0 for floating-point results because we hadn't set the ST0_FR bit to 0, and we had a mis-match between user libraries (MIPS3k-compatible) and the floating point registers. We noticed the problem when we couldn't run "ps" or "rm" correctly and tracked it down from some old postings by Ralf and friends. Maybe this is your problem, too? I added this to our setup call: set_cp0_status(ST0_FR, 0); Steve
