Ciao ragazzi, monitorando il mio hardware mi accorgo di una cosa:
CPU
product: Intel(R) Pentium(R) 4 CPU 2.40GHz
vendor: Intel Corp.
bus info: cpu@0
version: 15.2.7
slot: Socket 478
size: 2400MHz
capacity: 3GHz
clock: 133MHz
capabilities:
mathematical co-processor,
FPU exceptions reporting,
wp,
virtual mode extensions,
debugging extensions,
page size extensions,
time stamp counter,
model-specific registers,
4GB+ memory addressing (Physical Address Extension),
machine check exceptions,
compare and exchange 8-byte,
on-chip advanced programmable interrupt controller (APIC),
fast system calls,
memory type range registers,
page global enable,
machine check architecture,
conditional move instruction,
page attribute table,
36-bit page size extensions,
clflush,
debug trace and EMON store MSRs,
thermal control (ACPI),
multimedia extensions (MMX),
fast floating point save/restore,
streaming SIMD extensions (SSE),
streaming SIMD extensions (SSE2),
self-snoop,
HyperThreading,
thermal interrupt and status,
pending break event,
cid
configuration:
id=0
path: /0/4
ma risulta anche:
CPU DISABLED
product: ( )
vendor: Unknown
version: 15.2.7
slot: Socket 478
size: 2400MHz
capacity: 3GHz
clock: 133MHz
capabilities:
HyperThreading
configuration:
id=0
path: /0/5
orbene sarà che il processore ha funzionalità HT e io non lo sapevo?
Ho ricompilato il kernel attivando SMP e APIC,ma il risultato non mi pare
cambiato..

eccetera, eccetera...
il bios non contiene nessuna voce al riguardo che io possa modificare.
/proc/cpuinfo mostra un processore solo..
ma allora chi è questo processore fantasma? Ha HT effettivamente attivabile in
qualche modo? o è il mio bios o la mobo che sono farlocche ( può essere)?
Grazie a chi potrà spiegarmi cosa manco
ciao
