Hi Juerg, > You need a newer cpuid to display some additional data: > http://freshmeat.net/redir/cpuid_2/63002/url_tgz/cpuid-20060917.src.tar.gz Thanks for the hint! although the link you provided did not work, I found the package somewhere on the net, and here's the output: CPU: vendor_id = "CentaurHauls" version information (1/eax): processor type = primary processor (0) family = Intel Pentium Pro/II/III/Celeron, AMD Athlon/Duron, Cyrix M2, VIA C3 (6) model = 0xd (13) stepping id = 0x0 (0) extended family = 0x0 (0) extended model = 0x0 (0) (simple synth) = VIA C3 / C3-M / C7 / C7-M / Eden ESP 7000/8000/10000 (unknown model) miscellaneous (1/ebx): process local APIC physical ID = 0x0 (0) cpu count = 0x0 (0) CLFLUSH line size = 0x8 (8) brand index = 0x0 (0) brand id = 0x00 (0): unknown feature information (1/edx): x87 FPU on chip = true virtual-8086 mode enhancement = true debugging extensions = true page size extensions = true time stamp counter = true RDMSR and WRMSR support = true physical address extensions = true machine check exception = true CMPXCHG8B inst. = true APIC on chip = true SYSENTER and SYSEXIT = true memory type range registers = true PTE global bit = true machine check architecture = false conditional move/compare instruction = true page attribute table = true page size extension = false processor serial number = false CLFLUSH instruction = true debug store = false thermal monitor and clock ctrl = true MMX Technology = true FXSAVE/FXRSTOR = true SSE extensions = true SSE2 extensions = true self snoop = false hyper-threading / multi-core supported = false therm. monitor = true IA64 = false pending break event = true feature information (1/ecx): PNI/SSE3: Prescott New Instructions = true MONITOR/MWAIT = false CPL-qualified debug store = false VMX: virtual machine extensions = false Enhanced Intel SpeedStep Technology = true thermal monitor 2 = true context ID: adaptive or shared L1 data = false cmpxchg16b available = false xTPR disable = true extended processor signature (0x80000001/eax): generation = 0x0 (0) model = 0x0 (0) stepping = 0x0 (0) (simple synth) = unknown extended feature flags (0x80000001/edx): x87 FPU on chip = false virtual-8086 mode enhancement = false debugging extensions = false page size extensions = false time stamp counter = false RDMSR and WRMSR support = false physical address extensions = false machine check exception = false CMPXCHG8B inst. = false APIC on chip = false SYSCALL and SYSRET instructions = false memory type range registers = false global paging extension = false machine check architecture = false conditional move/compare instruction = false page attribute table = false page size extension = false multiprocessing capable = false AMD multimedia instruction extensions = false MMX Technology = false extended MMX = false SSE extensions = false AA-64 = false 3DNow! instruction extensions = false 3DNow! instructions = false brand = " VIA C7 Processor 1500MHz" L1 TLB/cache information: 2M/4M pages & L1 TLB (0x80000005/eax): instruction # entries = 0x0 (0) instruction associativity = 0x0 (0) data # entries = 0x0 (0) data associativity = 0x0 (0) L1 TLB/cache information: 4K pages & L1 TLB (0x80000005/ebx): instruction # entries = 0x80 (128) instruction associativity = 0x8 (8) data # entries = 0x80 (128) data associativity = 0x8 (8) L1 data cache information (0x80000005/ecx): line size (bytes) = 0x40 (64) lines per tag = 0x1 (1) associativity = 0x4 (4) size (Kb) = 0x40 (64) L1 instruction cache information (0x80000005/ecx): line size (bytes) = 0x40 (64) lines per tag = 0x1 (1) associativity = 0x4 (4) size (Kb) = 0x40 (64) L2 TLB/cache information: 2M/4M pages & L2 TLB (0x80000006/eax): instruction # entries = 0x0 (0) instruction associativity = L2 off (0) data # entries = 0x0 (0) data associativity = L2 off (0) L2 TLB/cache information: 4K pages & L2 TLB (0x80000006/ebx): instruction # entries = 0x0 (0) instruction associativity = L2 off (0) data # entries = 0x0 (0) data associativity = L2 off (0) L2 unified cache information (0x80000006/ecx): line size (bytes) = 0x40 (64) lines per tag = 0x1 (1) associativity = 0xa (10) size (Kb) = 0x80 (128) 0xc0000001: eax=0x00000000 extended feature flags (0xc0000001/edx): alternate instruction set = false alternate instruction set enabled = false random number generator = true random number generator enabled = true LongHaul MSR 0000_110Ah = false FEMMS = false advanced cryptography engine (ACE) = true advanced cryptography engine (ACE)enabled = true 0xc0000002: eax=0x00000000 ebx=0x08000810 ecx=0x08100f13 edx=0x42040000 0xc0000003: eax=0x57762abe ebx=0xce237d7f ecx=0x5ee56564 edx=0xe8619e36 (multi-processing synth): none (synth) = VIA C3 / C3-M / C7 / C7-M / Eden ESP 7000/8000/10000 (unknown model) -- Michael Reinelt <michael at reinelt.co.at> http://home.pages.at/reinelt GPG-Key 0xDF13BA50 ICQ #288386781
