This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950 SCSI driver for FreeBSD. I started from the 2.0R version and mostly rewrote it. New features are: 1) New probe algorithm. Old driver read the BIOS region of the adapter memory and find the copyright string. The problem was in the BIOS itself: it conflicted with IDE disks. The solution was to unplug it and make the probe algorithm to work without it. 2) Proper timeout handling in numerous places where the driver polls waiting for some event. 3) Assembler flagments added in critical places, mostly for data transfer to of from the target. It was possible to make it faster, but at the price of decreasing reliability. 4) Target-dependent delays when waiting for REQ deassert event. Some devices seem to be slower (CD-ROMS, some tape drives), and some seem to be too fast (disks). The driver tests the REQ deassert timeout for each target and then uses it for polling. 5) Device flags added for SCSI parity control and sense request priority control. 6) Generic cleanup, after which the driver became much more readable (at least by me:). 7) Target data parity error logging is limited to avoid log file overflow. 8) Manual page added.

\ \___ / |
Welcome to the ALPHA release of FreeBSD 2.0 - the /- _ `-/ '
first public snapshot of our new 4.4BSD Lite based (/\/ \ \ /\
operating system environment. This install proce- / / | ` \

This install procedure is ALPHA code, and `--{__________)
may very possibly *DESTROY* the contents of your
ENTIRE DISK! Please do not proceed with this installation
unless you've adequately backed up your data first!
If any errors occur during this installation, you can see them
by toggling over to the alternate screen - type ALT-F2 to switch
over, ALT-F1 to switch back to the install screen. The debugging
output on the second screen may be very valuable to us in understanding
your bug report, so please be sure to take note of it when reporting
any failures in the installation! Thanks!
Menus and scrolling output windows may be traversed with the arrow
and Page Up/Page Down keys. To suspend the installation at any point,
hit ESC twice. Hitting TAB will move the focus to different controls.
If you've ever dealt with a DOS installation, you'll know how to deal
with this.
For a more complete description of what's new in this release, please
see the release notes.
For more documentation on this system, it is recommended that you purchase
the 4.4BSD Document Set from O'Reilly Associates and the USENIX Association.
ISBN 1-56592-082-1 We have no connection with O'Reilly, we're just
