Dell PowerEdge 400SC, 6.2-PRERELEASE (altho this is an old issue)
dmesg says:
acd0: DMA limited to UDMA33, controller found non-ATA66 cable
acd0: DVDR <LITE-ON DVDRW SOHW-1633S/BS0K> at ata1-master UDMA33
cd0: 33.000MB/s transfers
The controller is properly probed as, "atapci0: <Intel ICH5 UDMA100
controller>"
This DVD isn't writing discs as fast as other brands on other
machines and OS's (such as MacOS X). Lite-On has a newer firmware
that I have not tried. But first was checking for any sort of errors
or irregularities and came across this mismatch.
Lite-On says "Supported transfer mode : PIO mode 4, DMA mode 2 and
Ultra DMA mode 2", so is there something I should do to my FreeBSD to
make this device happier?
