Hello
I've an Acer Travelmate Laptop with Celeron2.5.Ghz and Kernel 2.6.11 running. I examined the output of dmesg and today and noticed some strange lines at the beginning:
| Code: |
Linux version 2.6.11-gentoo-r4 (root@fermat) (gcc-Version 3.4.3-20050110 (Gentoo Linux 3.4.3.20050110-r1, ssp-3.4.3.2

SMP mptable: bad signature [0x0]!
BIOS bug, MP table errors detected!...
... disabling SMP support. (tell your hw vendor)

Local APIC disabled by BIOS -- you can enable it with "lapic"
mapped APIC to ffffd000 (011df000)

The lines that confuse me are:
| Code: | | SMP mptable: bad signature [0x0]! |
and
| Code: | | Local APIC disabled by BIOS -- you can enable it with "lapic" |
What does that mean? How can I enabled that?
