Ever since I was first installing Mandrake during boot I see these kernel messages

As taken from syslog
Code:
Aug 23 11:49:29 phoenix9 kernel: NFORCE2: IDE controller at PCI slot 0000:00:09.0
Aug 23 11:49:29 phoenix9 kernel: NFORCE2: chipset revision 162
Aug 23 11:49:29 phoenix9 kernel: NFORCE2: not 100%% native mode: will probe irqs later
Aug 23 11:49:29 phoenix9 kernel: NFORCE2: BIOS didn't set cable bits correctly. Enabling workaround.
Aug 23 11:49:29 phoenix9 kernel: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
Aug 23 11:49:29 phoenix9 kernel: NFORCE2: 0000:00:09.0 (rev a2) UDMA133 controller
Aug 23 11:49:29 phoenix9 kernel:     ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
Aug 23 11:49:29 phoenix9 kernel:     ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
My question is what does it mean by BIOS doesnt set cable bits correctly?
Also (how) can I fix it?

This may not seem like much of a problem since there is a workaround but I wanted to install debian and when I tried it just got to about the point in boot where those lines would come up in mandrake and hung. "Linux 2.6.3-7mdksmp"

Please help. If you need ay other logs or config files just ask.
