Ohi.. il mio PC è morto e mi hanno passato un "muletto" con un P4 3.2MHz.. Con la mia vecchia Debian 32 bit mi va leeeenttiisssimo (rispetto al'AMD Athlon 4000+ che avevo)..

Ho dato i comandi dmidecode -t processor I find e cat /proc/cpuinfo e sembra che vada con il 64 bit, allora volevo piallare la vecchia Debian e reinstallarne una nuova 64 bit.. ma mi pare strano che il P4 supporti il 64 bit, come invece riporta dmidecode.. mi devo fidare ?? E poi come mai cpuinfo riporta due CPU (0 e 1) ?? Questi sono i due output:

codice:
lobLinux:/home/lobianco# dmidecode -t processor I find
# dmidecode 2.9
SMBIOS 2.4 present.
