where do you overridee the idebus setting?

Hi

During boot I notice that the system says (roughly);
assuming 33 Mhz, override with idebus=xx

Where do you do this??

In your bootloader config, example:

/boot/grub/menu.lst:
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/mapper/arch-root vga=773 pci=bios disablemodules=it821x ro idebus=xx
initrd /kernel26.img

Where xx is your desired bus speed. But if you use DMA (which you probably do), setting this is pointless.

Thanks, and yes, I do use DMA. Just thought the lack of a few digits was slowing down my system.

The idebus setting is used until DMA kicks in. Given that the Arch stock kernel is configured to use DMA by default, DMA kicks in straight away and idebus is ignored.
