Hello. After I did a cvsupdate today and recompiled world/kernel, I realized that DVD/CDROM now is by default in PIO mode 4. I have to bring them back to DMA explicitely by setting hw.ata.atapi_dma="1" in /boot/loader.conf.local. Is this right or is this a weird behaviour of the widely unsupported (and therefore running in some GENERIC modes) ASUS A8N-SLI (nForce4 based Socket939 mainboard)? Looking at dmesg output, the harddisk attached to the nForce4 SATA II controler is said to be driven in UDMA33 mode by a GENERIC-ATA driver for this still unsupported chipset. Can I trust this message or is it simply a dummy message and the harddisk is driven as SATA150 (Maxtor 6B200MO, 200GB, NCQ capable)? Oliver
