Subject says it all really.

Dmesg advised me to send this - its from a 2.4.21pre4 kernel (I think its pre4
- - its a Mandrake patched one, but I figured the APIC stuff would be common to
a vanilla kernel)

I appear to have no issues with enabling APIC related stuff on this board,
which is nice :)

As an aside, does anyone know why my onboard drive controlers are having dma
disabled? (hda - hdd are on the KT400 ATA133 controler)

Cheers,

Mark.
