Of course FEN: 3r1rk/pp1q2b/3p2pp/PP1Np2n/2Pp1p/B2P2Pb/3QPPBP/R4RK w See above. BTW the hardware is a Ultra Sparc with 2 procs. fpversion gives: A SPARC-based CPU is available. CPU's clock rate appears to be approximately 166.8 MHz. Kernel says CPU's clock rate is 168.0 MHz. Kernel says main memory's clock rate is 84.0 MHz. Sun-4 floating-point controller version 0 found. An UltraSPARC chip is available. FPU's frequency appears to be approximately 170.5 MHz. Use "-xtarget=ultra" code-generation option. The OS is Solaris 7 from May 99. It's the 64-bit version. The compiler is gcc2.95 Kind regards Bernhard
