You need an IOAPIC. The local APIC is basically just the part of the CPU that receives messages from the IOAPIC, if present.
By the way, it is a bad idea to use front-side-bus interrupt delivery on some (all?) Intel mobile processors/chipsets. This prevents entering C3, if I remember correctly. The real details are in the i850-M databook... Does turning on IOAPIC+local APIC enable FSB-interrupt mode in Linux? What about also turning on message-signalled interrupts? Seems we use the local-apic instead of the IO(x)APIC for MSI. ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285
