 Intel Corp. 82801AA IDE: IDE controller on PCI slot 00:1f.1
 Intel Corp. 82801AA IDE: chipset revision 2
 Intel Corp. 82801AA IDE: not 100% native mode: will probe irqs later
 PIIX: Intel Corp. 82801AA IDE UDMA66 controller on pci00:1f.1

wait a couple of seconds

      ide0: BM-DMA at 0x1020-0x1027, BIOS settings: hda:DMA, hdb:pio
      ide1: BM-DMA at 0x1028-0x102f, BIOS settings: hdc:pio, hdd:DMA

OOPS!!

I have just hdam which is configured to use DMA66 as default, as I can see
from 2.4.18 boot messages.
Then i have an ATA cdrom on hdc.

me too.

Tomorrow I will provide more details on the disk. I use DMA as default,
and not PIO.
