Cool How to disable DMA in Partition check and Creating root device


I am running RH9 with a partition of a Maxtor drive as my hda. I am trying to eliminate some error messages, and some delays, from my boot sequence. One thing I did was to go into the GRUB boot loader and place

enable_ata_dma = false

on the kernel= line, which eliminated an attempt to start the Maxtor drive in UDMA mode which my hardware can't support. Later, at the end of the start sequence, I enable the tuned DMA modes which I found with hdparm.

But the UDMA attempt happens at two other places in the boot sequence: in the Partition check, and in the Creating root device activity. Can someone tell me if there is any convenient place where these activities can be tweaked?

Thanks,
....Monty.
