I have a remote server, and I'd like to know if it will support 64-bit instructions. Is there some way I can tell? It's running 32-bit FreeBSD right now. >From dmesg.boot: Timecounter "i8254" frequency 1193182 Hz quality 0 CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2387.76-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf29 Stepping = 9 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x4400<CNTX-ID,<b14>> Logical CPUs per core: 2 real memory = 1073676288 (1023 MB) avail memory = 1041502208 (993 MB) ACPI APIC Table: <DELL PE1750 > FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 I've had no luck trying to search for the id/stepping. Would the feature list show x64 support?
