You can list the modes your drives are currently using with the following command (as root): atacontrol mode 0 (1st channel) atacontrol mode 1 (2nd -"- ) For performance reasons you can try whether disabling DMA mode for your ATAPI devices is enough, i.e. your /boot/loader.conf should look like this: hw.ata.atapi_dma="0" Regards, Simon [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/XG6+Ckn+/eutqCoRAplCAJ9ggob9nk6WRXqG5m2HmZZEIc/e8ACg3POQ hRzb4Jj8BnxjTNJFW/7TZxQ= =EK2r -----END PGP SIGNATURE-----home | help
