>Description:
The FX4830T CDROM is autosensed as UDMA33. Frequent hardware errors are reported when using the drive in this mode. "atacontrol mode 1 pio4 pio4" eliminates the hardware errors.
There is also a problem with atapicam installing this drive as da0 instead of cd0.

>Fix:
atacontrol mode 1 pio4 pio4 allows acd0 to function properly. I do not know how to correct the atapicam issue.
