of config so YOU MUST RECOMPILE CONFIG. Modifying config was the cleanest
solution to integrating this driver into the tree which will become more
obvious in the next commit.
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.

Smack the netboot program around so that it will allow the user to
specify mount options. [So that you can boot from a privileged port]
Change the default boot image name in netboot to /kernel, then strip
the leading slash when actually going out to get the NFS file handle.
Added support for 3Com 3c503 cards. Also added another command to
the (trans) that allows you to switch the 3Com's on-board transceiver
on and off. (ether.c, ether.h, bootmenu.c)
Modified the Makefile to support new compile-time options for 3c503
cards:
-DINCLUDE_3COM Include support for 3c503
-D_3COM_BASE=0x300 Define 3c503 base i/o address (if not
specified, 0x300 is the default)
-D_3COM_USE_AUI Disable the 3c503's transceiver by
default (without this flag the transceiver
is on by default)
buffering scheme and make it more in tune with FreeBSD's vfs_bio
implementation. The filesystem seems fairly stable, but I wouldn't recommend
it to anyone not willing to experience problems. This is very green code and
has the limitation that YOU CAN ONLY HAVE ONE LFS PARTITION MOUNTED AT A TIME.
What LFS is good for:
Non fsynced writes FASTER THAN FFS
Large deletions Increadibly fast
Reads are a little bit slower than FFS right now, but that is a factor of
how under optimized this code is. LFS should in theory perform at least as
well as FFS under fsync (iozone) type loads, and this is what I'm currently
working on.

Don't clobber the last page of memory (where the message buffer is). Some
BIOS don't gratuitously wipe it out on reboot.
Remove bogus declaration of Debugger(). Call Debugger() even if DDB is
not defined, but still call panic() after Debugger() returns, although
most other SCSI drivers just call Debugger().
printf() is inconsistent with the prototype for the library printf() and
gets declared if DIAGNOSTIC is defined because <vm/vm_page.h> includes
<sys/systm.h>.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.

Alphabetize.
Write all i/o functions in sleep so that we don't use anything from
NetBSD.
Restore the correct type of u_int for ports. This saves a whole cycle
per i/o on 486's.
Change `inline' back to __inline to avoid compiler warnings with
-Wreally-all.
Don't implement bdb() unless BDE_DEBUGGER is defined. Declare bdb_exists
outside the function to avoid hundreds of compiler warnings.
Let the compiler pick the register in asms if possible.
Implement ffs() using inline asm(). gcc provides a slightly different
one. It was broken in gcc-2.4.5 but works now. Declaring a correct
version inline ensures getting a correct version. FreeBSD-1.1.5 has
an slow inline version but FreeBSD-2.0 has a library version (which
probably never gets used).
Do inb() and outb() without using %edx for constant ports below 0x100.
Remove casts to the same type in queue functions.
Declare prototypes for everything implemented i386/*.s and also for
everything that is normally implemented as an inline here (I don't
like the current complete dependency on gcc). Ifdef out the prototypes
that are declared elsewhere. THere should be a separate header to
declare things implemented in i386/*.s, but then it would be harder
to override declarations with inlines.

with the current default exception (un)mask. There should be no such
processes unless you change the mask. Someday the mask should be
changed to the IEEE default of everything masked. The npx state
gets saved so that it can be checked and this may have the side effect
of fixing a bug that was reported for 1.1.5. (npx exceptions may
sometimes leak across exits and clobber another process. I can't see
how this can happen.)
Get some missing/wrong declarations from headers now that the headers
have them.
I couldn't find a better way to avoid compiler warnings about
redundant and/or inconsistent declaration of ffs(). I'd like to
be able to declare prototypes in general headers without committing
to implementing them as `static inline' or `extern', but there
seems to be no way to do this with gcc-2.6.1. E.g.,
int foo(void);
static __inline int foo(void) { return 1; }
causes a warning about the linkage mismatch, while the opposite
order causes a warning about the redundant declaration.

Use "correct" and consistent types for interrupt handlers.
Remove a mailing address from the code.
Fix type mismatches found by adding prototypes.
Partly support BDE_DEBUGGER. Still broken by conflict with APM. Does
nothing if BDE_DEBUGGER is not defined.
Clean up prototypes and data declarations. Declare most of the segment
