noapic boot option

jalldridge · 04-01-2005, 02:25 AM

Hi guys,

To be able to run mdk 10.1 I have to use the command 'linux noapic'.

Now I know that this turns off kernel support for apic (advanced programmable interrupt controller I later found out), but what exactly is this doing (in laymans terms)?

What is the impact on my system by doing this?

What wont I be able to do :-)

It appears that many people have to run linux this way but I have yet to find out what this really does.

Thanks for input!

Here you find a post about this. It has a link to a page, where the Advanced Programmable Interrupt Controller is explained in detail.
