I recently installed the November RELEASE kernel of FreeBSD on my
66DX2/4(big)MB w/ toshiba scsi2 and have noticed _Major_ improvements
over the October kernel release. I assume this improvement relates
to the groovy little message at boottime: "bt0: ........ eisa dma"
The author - Julian might be follow up for you. but let me write
down a memo for you.
The message "bt0:..." is just show a current board configurataion
thorough the specified I/O port. Another word, bt742 driver DOES NOT
set it up like eisa dma mode nor 33MB/sec bursting..... Don't forget
set the board by EISA-Config utility.
[valuable stuff deleted]
I'm curious myself on exactly how close to an optimum driver for the
*BSD's are in their current src-trees (33MB/sec bursting transfer mode?)
Again, "Up to board setting by you!!"
Enjoy
Atsushi.
