Right!
Well, APIC supports more IRQs. But, do u really need it?
If U are not sure about that, just open your Device Manager and U can find out how many IRQs u need. Normally, U dont need more than 16, then U can disable APIC with no trouble.
Another benifit is U may gain better performance with APIC disabled. :P

事實上目前的電腦使用pic是不太好的,假如要做irq sharing他會有很多問題
就像之前網友所說,很多pci device使用pic的irq sharing都會產生問題
8259 pic的效率應該是很差的,他跟apic的差別其實不光是多了八組irq
smp的系統當然也不可能用pic mode(不過nforce當然沒有這問題)
基本上除非在pic上避免所有的sharing,否則apic都是好得多了
目前主機板想想光看內建音效,網卡,usb,加上必備的顯示卡
多一兩個device,要避免所有sharing,或考慮應該哪些device來sharing
雖然不是不行,但是已經不是一件很方便的事了
