to handle this, but it is good (and simple!) enough for now. It'd be
improved by moving some more files around and trying to make it more
consistent with "regular" installs.
The problem is that the build results are completely different under OS X
than those produced in other systems.
Not bumping PKGREVISION because this was unbuildable before.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

penalty. (Stanislav)
- Fixed pcipnic register access (Volker)
- Limited write support for TFTP server in 'vnet' networking module added (Volker)

- New floating point emulator based on SoftFloat floating point
emulation library.

- Cirrus SVGA card emulation added
- status bar with indicators for keyboard, floppy, cdrom and disk (gui dependant)
- many improvements in Bochs emulated I/O devices (e.g. PCI subsystem)
Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
And remove references of it from Makefile.
The HTML documentation is not installed in the first place.
TODO: maybe make a bochs-docs package that builds the documentation
from the docbook source.

- add wxWindows port (a graphical configuration interface and display lib)
and SVGAlib port (full screen display for Linux without X11).
- improvements in many I/O devices: for example up to 8 hard disks/cdroms,
TUN/TAP network interface, 360k floppies.
- improved MacOSX/Carbon interface and updated MacOS9port.
- GDB remote stub, allows symbolic debugging with Bochs simulation.
- support for up to 32gig hard disk images.
-------------------------------------------------------------------------
Changes in 1.4.1 (June 22, 2002):
- now cdrom is enabled in configure, unless you specifically disable
it with --disable-cdrom. (Christophe)
- fix compile error in main.cc when SMP or APIC is enabled (Dave)
- the runtime menu now displays 11 (continue) by default (Bryce)
- initialize DMA controller before floppy and SB16
- fix DMA panic when installing win95 (Volker)
- first character of the vga bitmap is blank on win32 (Volker)
Before, it was incorrectly coded as a '@'.
- AltGr key on European keyboards works now on win32 (Volker)
- fix problem with console/serial port on Bochs exit (Volker)
- enable serial port for GNU and GNU/Linux (Volker)
- small documentation fixes (Volker)
- remove unnecessary include statements for X11 (Volker)
- italian keymap added (Emanuele Goldoni)
- fix win32 ethernet frames error. It will no longer reject packets
that are less than 60 bytes long. (Peter Tattam)
- BIOS fixes :
- win2k cd-boot (Christophe)
- emm386 crash (Dave)
- cs=0 at boot time (Christophe)
- keyboard failure in scandisk (Dave)
- fix bug in forming the 64-bit APIC base address from two 32-bit registers.
A compiler warning in cpu/proc_ctrl.cc pointed this out.
- fix default choice in the runtime options menu
It can boot a Norton Utilities CD, but not run any of the
utilities. That may be the known problem with the Windows 98 CD.
- - Add the ability, on NetBSD, to spin up the CD-ROM. This keeps
"disklabel cd0" while booted from the NetBSD 1.5.3 rescue floppy
from panicing the emulation, but it still doesn't return a label.
- - Go ahead and enable the network driver and dummy sound driver.
The network driver almost works under the NetBSD rescue floppy
(ifconfig works, but not ping). I have no way, currently, of
verifying the (dummy, silent) sound driver.
- - Bump to 1.4nb1.
of the more visible ones.
- ROM BIOS
- Christophe Bothamy added ability to boot from El Torito CDROM.
- VGA
- vga memory read/write functions in text mode fixed
- implementation of CGA mode 320*200*4 (patch from Sebastien Bechet)
- GUI changes
- cdrom button: click this to notify Bochs when you changed the CDROM (Volker)
- snapshot button: saves the text on the Bochs screen into a file called
snapshot.txt (Volker)
- copy button: on Win32 and X windows, copy the text on the Bochs screen
to the clipboard (Volker)
- paste button: on Win32 and X windows, paste the characters on the
clipboard into the Bochs window. This requires keyboard_mapping to
be enabled. (Bryce Denney)
- keyboard
- added an optional keyboard_mapping option that enables to use your
country specific keyboard with Bochs. If enabled, the keymap file must be
specified in bochsrc. The available keymaps are US, German, Spanish and
French for PCs running X11. Contributions are welcomed. (Christophe
Bothamy)
- added Windows(tm) key definitions (Volker Ruppert)
- added paste button, which causes the emulated keyboard to type characters
from the system clipboard. This only works when keyboard_mapping is
enabled. (Bryce Denney)
stable than, version 1.1.2. Extensive changes include a new text-based
configuration menu (which starts at launch and upon pressing the config
button), LBA support for hard disks, better error handling for "hard
disk" configuration errors, and a new VGABIOS (optional). Plus, bochs
can now simulate an SMP machine! [The last is not tested on NetBSD,
and is not enabled by default in the package.]
- updated Elpin VGA BIOS to version 2.40, and changed pointer in .bochsrc
- fixed .conf.x86 script so that it uses c++ instead of egcs for C++ files
- now Makefile targets that recurse into subdirectories use double colons,
so that it will always recurse into subdirectories. Now a single make
command should notice a modified source file in a subdir.
- fixed bug in bx_panic. If BX_PANIC_IS_FATAL==0 and a (non-fatal) panic
occurs, it used to call bx_atexit() and then return. It should never
call bx_atexit, which starts to shut down the simulator, unless it's
really going to quit!
- support 2.88 MB floppy disks
- since dataseghack is checked in as non-executable, invoke it with
"csh dataseghack"
- double fault patch from Thomas Petazzoni <thomas.petazzoni@ifrance.com>,
sourceforge patch #423726.
- removed -fno-builtin from fpu makefiles
- redefine u_char, u_short, etc. in order to not conflict with system
definitions of these same types.
- in cdrom.cc, remove the extern "C" { } structure around some of the
header files. This is no longer necessary.
- do not panic on hard disk command 0x1f2 (read sector count)
- in keyboard.cc:
- apply Todd Fries' reset patch
- recognize most of the "Grey" insert/delete/home/end/etc. keys the
same as keypad keys.
- removed panic on "kbd_ctrl_to_kbd(): got value of 0x??"
- implement mouse command 0xf6 (set defaults)
- apply Suboner@aol.com's Xwindows timing patch from
http://sourceforge.net/tracker/index.php?func=detail&aid=418730&group_id=12580
&atid=312580
- remove all patches from patches subdir which have already been applied.
The remaining ones are under consideration but not applied.
