 Hi,
 
 unfortunately I did not manage to get the Info re. the BIOS-Bug that was 
 mentioned in the amd64-Mailing-List-Post by Jung-uk Kim :-(
 
 So, would it be possible to "generally" limit the DMA-Size in the 
 ATA-Driver for the SB600?
 
 After running a few Tests I reverted back to the hw.physmem as I'm 
 afraid of having to re-apply the Mod. to the DMA code each time rebuild 
 the Kernel ;-)
 
 Cheers,
