DMA Mode for DVD Devices

Archived from groups: microsoft.public.win2000.general (More info?)

In the BIOS, for both the DVD-Writer and the DVD-ROM
the settings are
- Ultra DMA mode = 2
- PIO mode = 4
In the device manager the setting for both devices is
Transfer Mode 'DMA if available' and
Current Transfer Mode 'PIO Mode'.

How to get DMA mode for these two drives ?
Hints much appreciated.

Config: Win2000 Pro SP4
P4 2.4, 1 GB RAM
DVD-Writer: LG GSA-4160B
DVD-ROM: Toshiba SD-M1612
Both devices on the secondary IDE channel with the
DVD-ROM as master and the writer as slave.

Thank you for listening
