I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine. This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in. It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.
PCI and EISA front ends will show up as soon as I get my hands on
the cards. There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)
Thanks to AdvanSys for releasing this code under a suitable copyright.

64K. The change has essentially neutral effect on those machines with
little or no cache, and has a positive effect on "normal" machines
with 256K or more cache.
[long long] results when I last worked on them, but they are normally
used together with to daddr_t's and off_t's which are signed, so the
unsigned results did little except cause warnings.
The main change is from unsigned long unsigned int. It just needs to
be a 32-bit type and unsigned int is most natural. Using a non-long
type has the "advantage" of hiding bugs in the "machine-independent"
code where it prints foo_t's using %d or %x. These bugs are currently
hidden bug not compiling with -Wformat.
I tried changing vm_ooffset_t from long long to unsigned long long, but
that was wrong because vm_ooffset_t needs to be long to match off_t,
although file offsets are never negative.

Staticized it in userconfig. The one in pcvt is unused.
Removed bogus unused arg to getchar(). This should not have compiled
in the USERCONFIG_BOOT case, but the getchar() was also non-prototyped
and defined in K&R style.
Staticized the badly named global variable `next'. Even static variables
should have a unique module-specific prefix so that they can be referenced
easily in debuggers, etc.
on their own without even attempting to get concensus in the IETF, but
there are also lots of Win95/NT boxes out there.

NOT being maintained, that I vote for killing this document soon and
moving everything into the Handbook. The FAQ needs to be "driven" a lot
more aggressively than it has been, and since that's clearly never going to
happen then we should kill it to halt the spread of outdated information.
Major: When blocking occurs in allocbuf() for VMIO files,
excess wire counts could accumulate.
Major: Pages are incorrectly accumulated into the physical
buffer for clustered reads. This happens when bogus
page is needed.
Minor: When reclaiming buffers, the async flag on the buffer
needs to be zero, or the reclaim is not optimal.
Minor: The age flag should be cleared, if a buffer is wanted.
