Setting DMA for DVD

[Patrick Bowen]

Hi all:

I'm running 6.0 (rebuilt last night) on a dell C600 laptop. I've been 
trying to set DMA on for my DVD in loader.conf with the following, per 
the handbook;

	hw.ata.atapi_dma="1"

Unfortunately when I reboot, the drive is back to PIO4. I can set it 
maually with;

	atacontrol mode 1 wdma2 biospio

but, of course it reverts on reboot.

How do I make this persistent across reboots. Thanks in advance...

Patrick
