All,
I've have a proliant 1600 running rh73. But it's only seeing one cpu, according to what I know and see during boot, there should be two cpu (450 Mhz). the kernel is of smp type, what gives? This is a fresh install. here's the result of:
cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 5
model name : Pentium II (Deschutes)
stepping : 2
cpu MHz : 448.960
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes

Any idea? Thanks.

Are both processors seen in your bios ?
It happened to a friend on another arch., and inverting physically the processors fixed things. I nevertheless suppose he had a hardware prob in one slot...

dmesg | more and see that cpus are/aren't
detected during boot time like in my box:

Initializing CPU#0
Detected 349.407 MHz processor.
I would also compare to previous boots to see
if something went wrong since then.

Actually this one is from SMP-Howto:

Put it into MP1.1/1.4 compliant mode.

check "Configure Hardware" -> "View / Edit details" -> "Advanced mode" (F7 I think) for a configuration option "APIC mode" and set this to full Table mode . This is an official Compaq recommandation although I was never able to find this option in the BIOS...

All,I've figured it out. I used the smart start cd to configure second cpu. RH7.3 see both cpu now. Thanks for all your help.
