nforce2 chipset :IRQ troubles at boot!

hello, i'm a niewbies in the linux world.

I've a problem in mandrake 10.1 community at boot.

my config:

- motherboard: Asus A7N8X-X (Nforce 2 chipset) with a Phoenix bios (1009 rev)
- HD:maxtor 120 Gb (6Y120L0)
- kernel:

Some times, when mandrake boots, The IRQ probe failed and so, the IEQ of my HD (IRQ 14 normaly) goes to the IRQ 7.
So, no dma, KDE run slowly and the sound is jerky,...

Check the other threads, there was a recent discussion about the nforce chipset that covered this via an update.

All you need to do is open the control centre.
Under the Boot heading click on bootloader.
You will see 3 options with check boxes in front of them. You want to check the bottom two. One of them says "Force no local APIC" . I can't remember what the other was.
The option at the very top says " Enable ACPI". You will want to leave this one alone.
Once you have checked (put an X in) the bottom two options, just click next and follow the instructions.
