Ok Tech types: APIC enabled/disabled?

[CavemanJ]

What, exactly, is APIC mode in the bios, and is it better to have it enabled or disabled?

And is it one of those settings that changing it means ya gotta reinstall the OS?

And what kinda headaches would it cause if you had it enabled, installed win2k pro, then had to rma the board and didna enable it in the bios the first time ya booted after getting the board back?

its one of those change it b4 ya install the OS... i believe

if you have an MSI mobo, the manual contains a description of what it is..
basically it expands the number of IRQ's available to hardware.

I currently have APIC enabled, here take a look at my irq's:



IRQ 0   System timer   OK
IRQ 1   PC/AT Enhanced PS/2 Keyboard (101/102-Key)   OK
IRQ 3   Communications Port (COM2)   OK
IRQ 4   Communications Port (COM1)   OK
IRQ 6   Standard floppy disk controller   OK
IRQ 8   System CMOS/real time clock   OK
IRQ 12   Microsoft PS/2 Mouse   OK
IRQ 13   Numeric data processor   OK
IRQ 14   Primary IDE Channel   OK
IRQ 15   Secondary IDE Channel   OK
IRQ 31   VIA Rev 5 or later USB Universal Host Controller   OK
IRQ 31   VIA Rev 5 or later USB Universal Host Controller   OK
IRQ 40   Creative SB Live! Value (WDM)   OK
IRQ 48   D-Link DFE-538TX 10/100 Adapter   OK
IRQ 128   NVIDIA GeForce4 MX 440   OK

having no problems at all with this setup(XP Pro), and in AH.. i think i am average to below average for lockups and ctd's
