floppy driver (or in the hardware?). It turned out to be caused by
spurious interrupts, right after an FDC reset.
Also major cleanup in the low-level structure, there are now functions
performing error-checks for the FDC I/O.

correct console number for the VT_WAITACTIVE ioctl. Invalid console numbers
caused waiting on an invalid pointer.
Use bcopyw() instead of move_up() and move_down(). bcopyw() handles
overlapped copies and should be faster. Actually use bcopy(). bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit. bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.
You can now sling 14 devices off of a 274xT. In the process of adding
twin channel support, I removed all evident restrictions on supporting
Wide channeled devices, but I do not have a Wide controller to test them
on.
aic7770_seq.h, the pre-compiled header, is no longer needed since config
handles this dependancy.
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
has only 8K of shared memory. The only way to have it properly detected
is to zero and test a few bytes of memory just about the first 8K region.
If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.
I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).
- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
the last column, like it should. You don't really notice this unless you
use certain programs that write all the way out to, say, the 80th column,
like VMSmail. Along with a one-line fix for this are some changes to
implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
config file and give it a try. :)

is supposed to work except "media removal" (shutting down the vn driver)
while some partitions are open.
Fix some errnos: return ENOTTY, not ENXIO for unknown ioctls; return
ENODEV, not ENXIO for the unsupported dump operation.
worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.
Now floppy tape support is *disabled* unless you specifically
request otherwise. Poul wanted it this way, and I guess I'm not going to argue
though it may seem counter-intuitive. We can always change it back, later.
make the sequencer code fully compatible with the aic7870 (ie 294x adaptors).
I've also added to my local mods putting the sequencer into "FASTMODE" clock.
This gives upwards of 2M/sec write preformance improvement in some scenarios.
There haven't been any reports of this causing problems, and I have been
reaping the benifits of it for more than a week now.
This also includes a new version of the pre-generated file <ugh>

flags & 0x1. Somebody should build a kernel with this and see if
the floppy-tape damaged people can turn it off properly with userconfig.
I can't reproduce the original problem here.
and into ether_input(). It was silly to have bpf want this one way and
ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.
1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments

a discussion going on about removing this code from the burden of the
GPL, but it won't happen before Beta, and this code should be tested
before release.
Supports 27/2842 class adaptec cards and is almost capable of supporting
aic7870 based adapters (294X series cards). It does not support Wide
controllers or the second channel on Twin boards although I have work in
progress on getting both channels and running.
I have also added a few performance improvements to this version that give
us approximately a 25% boost over the original driver. These patches have
been submitted to the author.
