I'll get the output from dmesg tomorrow. Er the machine isn't on the net yet -- so i have to go home and copy it to a floppy and then email it to the list... As I noted a few minutes ago I am getting 10MB/S doing dd if=/dev/xxx bs=8192 of=/dev/null (i use ioctl -c 100 to watch the rate) I should get 20 to 25 MB /S so I think it is using dma 2 instead of dma 5 (it supports dma 6 but freebsd doesn't - yet). (er the 10MB/s is substained not from drive cache). Alan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
