It works only with Cyrix FPU, and this option should not be used with Intel FPU. options "CPU_BLUELIGHTNING_3X" CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning CPU if CPU supports it. The default is double-clock mode on BlueLightning CPU box. I read thet is says : "It works only with Cyrix FPU" for the first one, so should I use it? What about the second option? options "CPU_SUSP_HLT" CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU enters suspend mode following execution of HALT instruction. options "CPU_IORT=7" CPU_IORT defines I/O clock delay time. Default vaules of I/O clock delay time on Cyrix 6x86 is 7 (no clock delay) options "CPU_WT_ALLOC" enables write allocation on Cyrix 6x86/6x86MX and AMD K5/K6/K6-2 cpus. those should be ok right? options "CYRIX_CACHE_REALLY_WORKS" CYRIX_CACHE_REALLY_WORKS enables write-back CPU cache on Cyrix 6x86 whose revision < 2.7. I guess that depends on my rev. version. Do I need this : CPU_CYRIX_NO_LOCK enables weak locking for the entire address space # of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1. # Otherwise, the NO_LOCK bit of CCR1 is cleared. or is my rev. high enough (if it is 2.9)? I found this sites that talk about some of these : http://people.freebsd.org/~kato/cpuident.html http://wauug.erols.com/~balsa/linux/cyrix/p11.html Thank you, Gab -- _______________________________________________ Get your free email from http://mymail.bsdmail.com Powered by Outblaze
