Thankyou so much JO and AJS.
I got the kernel installed by just
#apt-get install kernel-image-2.6.8-11-amd64-k8-smp
and a reboot.
It booted the smp kernel by default :-)
2.6.8-11-amd64-k8-smp
it has detected both cpus too

but still the boot dmesg shows this for the SMP kernel
----------------------------------
Processor #0 15:5 APIC version 16
ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01] enabled)
Processor #1 15:5 APIC version 16
ACPI: LAPIC (acpi_id[0x03] lapic_id[0x82] disabled)
ACPI: LAPIC (acpi_id[0x04] lapic_id[0x83] disabled)
---------------------------------------------------------------------------------------------------
why is LAPIC disabled for processor 1?
please let me know if you need the full boot time dmesg :-)
Thankyou so much once again.
kind regards
Siju
