Hi, In ata(4), it states: hw.ata.atapi_dma set to 1 for DMA access, 0 for PIO (default is PIO). In src/sys/dev/ata/ata-all.c, this sysctl is by default set to 1 (on -CURRENT, and also on 5.3-RELEASE). Perhaps this patch is in order? --- share/man/man4/ata.4.orig Thu Dec 9 19:07:53 2004 +++ share/man/man4/ata.4 Thu Dec 9 19:08:08 2004 _at__at_ -86,7 +86,7 _at__at_ .It Va hw.ata.ata_dma set to 1 for DMA access, 0 for PIO (default is DMA). .It Va hw.ata.atapi_dma -set to 1 for DMA access, 0 for PIO (default is PIO). +set to 1 for DMA access, 0 for PIO (default is DMA). .It Va hw.ata.wc set to 1 to enable Write Caching, 0 to disable (default is enabled). .Em WARNING : -- Craig Rodrigues rodrigc_at_crodrigues.orgReceived on Thu Dec 09 2004 - 23:09:40 UTC
