Hi,

I'm having trouble burning CD's from FreeBSD 5.3 guest through WinXP =
host on VMWare Workstation 4.5.2=20

My VMWare workstation is complaining about DMA mode when I run:
"burncd -s 10 -f /dev/acd0 data test.iso fixate"

The error message from VMWare I get is:
"Your virtual machine has sent an ATAPI (CD-ROM) command that is only =
supported when programming the drive via DMA.  You will need to =
configure your guest operating system to use DMA when communicating with =
DVD/CD-ROM devices.
Note that some operating systems will report DMA is available without =
actually using it.  In those cases, normal CD-ROM operations will still =
be available, but special features will only be available if you =
re-configure the virtual device as a SCSI device."

FreeBSD gives the follwing:
"burncd: ioctl(CDRIOCINITTRACK): Input/output error"

I have the following lines in my loader.conf:
hw.ata.atapi_dma=3D"1"
hw.ata.ata_dma=3D"1"

and have also tried configuring dma when system is up by running:
atacontrol mode 1 udma4 udma4

Any Ideas?

Many thanks in advance,

Radster
