Hi all

 I have an Asus S8600.
 Mobile PIII 800Mhz + 192M RAM.
 If i select "Local APIC support on uniprocessors" the kernel while booting
says there's no APIC present.Why?
 I know the same problem with some other laptops.
 Others detect it.

 At home my Athlon Tunderbird + Asus A7V133-C with local APIC enabled detects
it but doesn seem to use it ...

 cat /proc/interrupts
  0: 375529 XT-PIC timer
  1: 7452 XT-PIC keyboard
  2: 0 XT-PIC cascade
  5: 113246 XT-PIC bttv, eth0
  8: 2 XT-PIC rtc
 10: 144373 XT-PIC EMU10K1
 11: 382444 XT-PIC nvidia
 12: 153864 XT-PIC PS/2 Mouse
 14: 12346 XT-PIC ide0
 15: 12 XT-PIC ide1
NMI: 0
ERR: 0

Anyway why do I need local APIC :) ?What are the advantages?Links?

Thank you very much for your kindness

 Best Regards,
