Reorganise the driver some what.
Rename tr_reset() to the more appropriate tr_stop().
Create a common tropic reset routine and use it in the frontends.
Move the code in tr_config() which is only used in the card attachment
routines into a new tr_attach() function.
Take adapter off the ring through tr_shutdown() in a shutdown hook.
This simplifies the bus-specific frontend.
where one side can think a connection exists, where the other side thinks
the connection was never established.
The original problem was first reported by Ty Sarna in PR #5909. The
original fix I made to the code didn't cover all cases. The problem this
fix addresses was reported by Christoph Badura via private e-mail.
Many thanks to Bill Sommerfeld for helping me to test this code, and
for finding a subtle bug.
rc.subr to the default rc.conf.
While this is no longer necessary to supress noise,
it increases the clarity of the situation and removes
one more bit of what should be adjustable configuration
from scripts that site admins shouldn't have to edit.
Addresses PRs misc/7406 and (partially) bin/7491.
older CHS interface. This works around stupid BIOSs who report that
int13 extensions are present and functional, but fail when you actually
use them. Like Adaptec SCSI BIOSs.
For the bootselector, there was no space to get the CHS info from
the BIOS. Instead, use a flag that can be set by fdisk. fdisk will
set it if one of the partitions on the disk is out of CHS reach
for this disk/BIOS, so that the bootselector will use int13 extensions.
This isn't so bad, because it needs to be configured via fdisk anyway.
Change the mbr manualpage to reflect some shorter error messages.
