mitch_de Posted June 1, 2008 Share Posted June 1, 2008 Hi, i am on the way to evaluate why my "About this Mac" crashes / logout. System Profiler runs with no problems, and all other things no problems. It must be to do with BIOS of my MSI P965 NEO-F., CPU E2160 (Dual Core Pentium 1.8) I do NOT need to set CPU=1 to boot without crash or to work. Maybe my BIOS reports some CPU things not the way OS X can use it. XP or Vista may didnt worry about that. So i know that there is an BIOS Mod thread, where nice KABYL works endless for modding such BIOSes. So i list here my sysctl -a (lists all variables of kernel). ... hw.logicalcpu_max: 2 hw.logicalcpu: 2 **** OK **** hw.physicalcpu_max: 2 hw.physicalcpu: 2 ***** THATS WRONG ***** Setting hw.physicalcpu=1 with sysctl -w xxxx cant work because its read-only. Is it possible to change something in the kernel to avoid hw.physicalcpu: 2, set it fixed to 1 ? I think near non has 2 physical CPUs (most have non server mainboards). Maybe that would be much easyer that to mod all those bioses - also mod them after each update. Here my complete sysctl list kern.bootargs: boot-uuid=99739A0B-3E1A-30D8-8EDD-76938AB74EEF rd=*uuid platform=ACPI kern.msgbuf: 4096 kern.wq_timer_interval_msecs: 40 kern.wq_max_run_latency_usecs: 500 kern.wq_reduce_pool_window_usecs: 3000000 kern.wq_stalled_window_usecs: 20000 kern.secure_kernel: 0 kern.cpu_currentfreq: 1500 kern.cpu_log: 0 kern.cpu_minfreq: 1000 kern.cpu_maxfreq: 1500 kern.cpu_temp_is_valid: 1 kern.cpu_temp: 54 kern.coolbook2_bus: 200 kern.coolbook2_temp: 54 kern.coolbook2_vid: 12125 kern.coolbook2_div: 9 kern.coolbook2_ctl: 0 kern.coolbook2_stseax: 100665640 kern.coolbook2_stsedx: 153618728 hw.ncpu: 2 hw.byteorder: 1234 hw.memsize: 2147483648 hw.activecpu: 2 hw.optional.x86_64: 1 hw.optional.sse4_2: 0 hw.optional.sse4_1: 0 hw.optional.supplementalsse3: 1 hw.optional.sse3: 1 hw.optional.sse2: 1 hw.optional.sse: 1 hw.optional.mmx: 1 hw.optional.floatingpoint: 1 hw.packages: 1 hw.tbfrequency: 1000000000 hw.l2cachesize: 1048576 hw.l1dcachesize: 32768 hw.l1icachesize: 32768 hw.cachelinesize: 64 hw.cpufrequency_max: 1800000000 hw.cpufrequency_min: 1800000000 hw.cpufrequency: 1800000000 hw.busfrequency_max: 800000000 hw.busfrequency_min: 800000000 hw.busfrequency: 800000000 hw.pagesize: 4096 hw.cachesize: 2147483648 32768 1048576 0 0 0 0 0 0 0 hw.cacheconfig: 2 1 2 0 0 0 0 0 0 0 hw.cpufamily: 1114597871 hw.cpu64bit_capable: 1 hw.cpusubtype: 4 hw.cputype: 7 hw.logicalcpu_max: 2 hw.logicalcpu: 2 hw.physicalcpu_max: 2 hw.physicalcpu: 2 machdep.pmap.hashmax: 11 machdep.pmap.hashcnts: 944925 machdep.pmap.hashwalks: 893564 machdep.cpu.address_bits.virtual: 48 machdep.cpu.address_bits.physical: 36 machdep.cpu.cache.size: 1024 machdep.cpu.cache.L2_associativity: 4 machdep.cpu.cache.linesize: 64 machdep.cpu.arch_perf.fixed_width: 40 machdep.cpu.arch_perf.fixed_number: 3 machdep.cpu.arch_perf.events: 0 machdep.cpu.arch_perf.events_number: 7 machdep.cpu.arch_perf.width: 40 machdep.cpu.arch_perf.number: 2 machdep.cpu.arch_perf.version: 2 machdep.cpu.thermal.ACNT_MCNT: 1 machdep.cpu.thermal.thresholds: 2 machdep.cpu.thermal.dynamic_acceleration: 0 machdep.cpu.thermal.sensor: 1 machdep.cpu.mwait.sub_Cstates: 544 machdep.cpu.mwait.extensions: 3 machdep.cpu.mwait.linesize_max: 64 machdep.cpu.mwait.linesize_min: 64 machdep.cpu.cores_per_package: 2 machdep.cpu.logical_per_package: 2 machdep.cpu.extfeatures: XD EM64T machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL EST TM2 SSSE3 CX16 TPR PDCM machdep.cpu.brand: 0 machdep.cpu.signature: 1789 machdep.cpu.extfeature_bits: 537919488 1 machdep.cpu.feature_bits: -1075053569 58269 machdep.cpu.stepping: 13 machdep.cpu.extfamily: 0 machdep.cpu.extmodel: 0 machdep.cpu.model: 15 machdep.cpu.family: 6 machdep.cpu.brand_string: Intel® Pentium® Dual CPU E2160 @ 1.80GHz machdep.cpu.vendor: GenuineIntel Also i added an screen output of IOREGISTRY of the CPU section.

~Eureka Posted June 1, 2008 Share Posted June 1, 2008 Hi, You can try this beta AppleSMBIOS to see if "About This Mac" still crashes. http://forum.insanelymac.com/index.php?act...st&id=28818 http://forum.insanelymac.com/index.php?sho...01902&st=20 (post #26) Chun-Nan Link to comment https://www.insanelymac.com/forum/topic/108078-to-kernel-developer-kernel-professionals-bios-modders/#findComment-766855 Share on other sites More sharing options...
mitch_de Posted June 1, 2008 Author Share Posted June 1, 2008 YOU GOT IT. I used the latest patched AppleSMBios-27V6 before which crashs About Mac since changing Board from ASUS 945 to MSI P965 ! THANK YOU Chun-Nan !!!! (again, i used your PCCArd things in an laptop) Link to comment https://www.insanelymac.com/forum/topic/108078-to-kernel-developer-kernel-professionals-bios-modders/#findComment-766953 Share on other sites More sharing options...
