SubjectLocal APIC(?)+PIII mobile
DateFri, 13 Dec 2002 11:56:11 +0000
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
CPU0
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,

João Seabra
