Hello

Cannot
read or play audio cdrom disks. 
run the Windows install for Win4BSD the install worked worked with a standard 
cdrom drive

Can
burn CD-R  (with cdrecord dev=1,0,0)
burn DVD-RW (with mkisofs)
play  Movie dvds.
read dvd disks
read data cdrom disks

I am using 6.1 Release.

/boot/loader.conf
atapicam_load="YES"
hw.ata.ata_dma="1"
hw.ata.atapi_dma="1"

I have set the mode for the device to UDMA33 from UDMA66.
How can I set this up so the drive boots as UDMA33? Do I add the following 
line into the device.hints:
hint.cd.0.mode="UDMA33"?

acd0: DVDR <DVD RW DRU-820A/1.0b> at ata1-master UDMA66
cd0 at ata1 bus 0 target 0 lun 0
cd0: <SONY DVD RW DRU-820A 1.0b> Removable CD-ROM SCSI-0 device 
cd0: 66.000MB/s transfers


I am receiving a following errors while booting
cd0: cd present [309837 x 2048 byte records]
