Thanks a lot! This gives quite a lot of info about the chip: Family: 6 Model: 6 Stepping: 0 Type: 0 Brand: 0 CPU Model: Celeron (Mendocino) Original OEM Feature flags: Onboard FPU Virtual Mode Extensions Debugging Extensions Page Size Extensions Time Stamp Counter Model-Specific Registers Physical Address Extensions Machine Check Architecture CMPXCHG8 instruction SYSENTER/SYSEXIT Memory Type Range Registers Page Global Enable Machine Check Architecture CMOV instruction Page Attribute Table 36-bit PSEs MMX support FXSAVE and FXRESTORE instructions Extended feature flags: Instruction TLB: 4KB pages, 4-way associative, 32 entries Instruction TLB: 4MB pages, fully associative, 2 entries Data TLB: 4KB pages, 4-way associative, 64 entries L2 unified cache: Size: 128KB 4-way associative. line size=32 bytes. L1 Instruction cache: Size: 16KB 4-way associative. line size=32 bytes. Data TLB: 4MB pages, 4-way associative, 8 entries L1 Data cache: Size: 16KB 4-way associative. line size=32 bytes. /dev/cpu/0/msr: No such file or directory Connector type: Socket 370 (370 Pin PGA) MTRR registers: MTRRcap (0xfe): MTRRphysBase0 (0x200): MTRRphysMask0 (0x201): MTRRphysBase1 (0x202): MTRRphysMask1 (0x203): MTRRphysBase2 (0x204): MTRRphysMask2 (0x205): MTRRphysBase3 (0x206): MTRRphysMask3 (0x207): MTRRphysBase4 (0x208): MTRRphysMask4 (0x209): MTRRphysBase5 (0x20a): MTRRphysMask5 (0x20b): MTRRphysBase6 (0x20c): MTRRphysMask6 (0x20d): MTRRphysBase7 (0x20e): MTRRphysMask7 (0x20f): MTRRfix64K_00000 (0x250): MTRRfix16K_80000 (0x258): MTRRfix16K_A0000 (0x259): MTRRfix4K_C8000 (0x269): MTRRfix4K_D0000 0x26a: MTRRfix4K_D8000 0x26b: MTRRfix4K_E0000 0x26c: MTRRfix4K_E8000 0x26d: MTRRfix4K_F0000 0x26e: MTRRfix4K_F8000 0x26f: MTRRdefType (0x2ff): 400MHz processor (estimate). Now, I realize no one will want to make 'supported' or 'guaranteed' recommendations, but I would certainly appreciate some pointers on taking the above information and determining the ideal CPU options to use in my kernel. I looked at the handbook, and can't find any such details or links. My main goal is to find out what CPU features are disabled through the kernel config, and enable them - particularly MMX support. Finally, I noticed my message log from bootup has the following: Features=0x183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR> Does this specify just detection or kernel config? It appears to match the features detected by x86info. Thanks for all the help!
