Hi everyone,
I have SCSI emulation on my CDR drive in order to burn and the like,
but I was confused by the following entries in /var/log/messages...
----------------------------------------------------------------------
Aug 5 12:18:48 localhost kernel: SCSI subsystem driver Revision: 1.00
Aug 5 12:18:19 localhost rc.sysinit: Setting clock (localtime): Mon
Aug 5 12:18:13 UTC 2002 succeeded
Aug 5 12:18:49 localhost kernel: scsi0 : SCSI host adapter emulation
for IDE ATAPI devices
Aug 5 12:18:19 localhost rc.sysinit: Loading default keymap succeeded
Aug 5 12:18:49 localhost kernel: Vendor: LITE-ON Model: LTR-24102B
Rev: 5S0J
Aug 5 12:18:19 localhost rc.sysinit: Setting default font (lat0-sun16):
succeeded
Aug 5 12:18:49 localhost kernel: Type: CD-ROM ANSI SCSI
revision: 02
Aug 5 12:18:19 localhost rc.sysinit: Activating swap partitions: succeeded
Aug 5 12:18:49 localhost kernel: hdc: DMA disabled
-----------------------------------------------------------------------
The last line says that DMA is disabled, but it refers to hdc. Since
my /dev/cdrom is linked to /dev/scd0, and /dev/cdrecorder is linked
to /dev/sg0, does that mean DMA is working anyhow? How can I tell?
(I was prompted into peeking around after burning seemed a little
slow..)
Thanks in advance,
Dave.
