hi,

i still can NOT enable hyperthread despite
enabled hyperthread in bios setup
compiled the kernel 2.5.75 with smp enabled
keyed in acpismp=force at linux loader

here is what i have in the /proc/cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Pentium(R) 4 CPU 2.66GHz
stepping : 7
cpu MHz : 2659.588
cache size : 512 KB
physical id : 0

fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : 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 ht tm pbe cid
bogomips : 5242.88

and here is partial listing of my /var/log/messages

=======================================

please note in the above listing there is a line
"kernel: CPU: Hyper-Threading is disabled"

well, how do i get hyperthread working in this machine?

thank you.

kayaker

ps, is your hypertread really working?

If you hear anything could you please e-mail me kevincwms@hotmail.com

Have you tried a later development kernel? They're up to 2.6.0-test4 last I checked.
