On this page you will a find a short guide on how to set up a Sony DRX-820UL
I wrote it because when I searched google I found nothing about this Hardware.
All comments, suggestions etc. are welcome. Please contact me at firstname.lastname@example.org.
Connecting via USB
Let's have a look at the easy stuff first.
You need the following configuration in the kernel (here at the moment 2.6.14):
# USB support
# USB Host Controller Drivers
Plug in the USB cable on the computer's side and into the DRX-820.
The drive is recognized as
Vendor: SONY Model: DVD RW DRU-820A Rev: 2.0b
Type: CD-ROM ANSI SCSI revision: 00
and the mass-storage driver should be loaded automatically (here that works
even with usbmgr, hotplug isn't a problem either).
Now you can address the DVD drive as /dev/scd0, if it is your only
SCSI (emulated) CD/DVD drive, else /dev/scd1 and so on.
You can eg mount a DVD by running # mount /dev/scd0 /cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
/dev/scd0 on /cdrom type udf (ro)
Connecting via Firewire / IEEE 1394
Plug in the firewire Cable (it doesn't matter which port you choose on the DVD
Load the modules ohci1394, sbp2 if they are not loaded automatically.
