Dear Tejun: The test results point to varied kinds and degrees of problems. At the moment. To avoid turning off anything fancy on systems involving SB600/700, we definitely need more info. Shane, can you please summarize chipset product lines and revisions and how they're configured

Hi Jeff: Do you have any suggestion on my plan to withdraw Tejun's forcing 32 bit DMA patch? As well as further validation to the 64 bit DMA capacity of SB600 SATA controller? Thanks Best Regards Shane -Original Message- From: Shane Huang Sent: Wednesday, January 23, 2008 3:44 PM
