This file has been in our main directory for years and years, and has not
|
|
been updated since nobody has tried to compile for MacOS pre-10 in a long
|
|
time. I didn't want to leave it sitting there since it is so incredibly
|
|
obsolete. I think it would be good to put it into the documentation
|
|
with proper warnings about the fact that it hasn't been updated in 4 years
|
|
and may need significant hacking to make it work again.

Changes by Bryce Denney 4/5/2001:
|
|
I moved the contents of macutils.h into osdep.h, and macutils.c
|
|
into osdep.cc. There are functions missing on other platforms too,
|
|
so I wanted to bring them all into the same place.

Status
|
|
------
|
|
|
|
This is an experimental Macintosh port of Bochs. The Mac port compiles fine
|
|
under CodeWarrior Pro R1 (CW12) and is capable of booting Win95 in command-
|
|
line mode and running DOS programs. A CodeWarrior project ("Bochs.proj") is
|
|
included (you may need to edit the type and creator information with ResEdit
|
|
in order for CodeWarrior to recognise it as a project file).
|
|
|
|
NOTE: MacBochs is very much a "work in progress", and much of the code is
|
|
incomplete. This preliminary version is being made available mainly to
|
|
interested developers who may want to contribute to the development of
|
|
MacBochs by contributing some code or testing it on their own Macs.
|
|
|
|
If anyone can test with some "clean" Windows installer disks, it would be
|
|
useful. I've been testing MacBochs with my SoftWindows HD image and disk
|
|
images derived from it, and I'm not sure if the various SoftWindows-specific
|
|
drivers are interfering.
|
|
|
|
23 Dec 98 - updated MacBochs to bochs-981222. The new version seems
|
|
noticeably faster. Finished implementing the Bochs headerbar. Added support
|
|
for ejecting floppy disks from within Bochs (click the Drive A: icon on the
|
|
headerbar or press Cmd-E).
|
|
|
|
17 Dec 98 - added real floppy disk support. Also optimized the graphics
|
|
screen drawing a bit more. Keyboard support still broken and in need of a
|
|
major overhaul. Does anyone have experience with KCHR resources and
|
|
KeyTranslate()?

How to Set up MacBochs
|
|
----------------------
|
|
|
|
This is a very brief, step-by-step guide on setting up MacBochs. More
|
|
detailed documentation will be available later.
|
|
|
|
- Step 1. Compile the version of Bochs you want to use (PPC, 68k or FAT) or
|
|
obtain a pre-compiled binary. There is a CodeWarrior project included with
|
|
the source distribution.
|
|
|
|
- Step 2. Create a hard disk image.
|
|
Bochs ALWAYS needs a hard disk image available to it, otherwise it won't
|
|
boot. To create a hard disk image on the Mac, you need to use a recent
|
|
version of DiskCopy.
|
|
|
|
First, create an untitled, empty folder anywhere on your Mac hard disk. Then,
|
|
launch DiskCopy and choose to create a folder image of that folder.
|
|
|
|
DO NOT ENTER THE DISK SIZE IN MEGABYTES. In the file "install.html" in the
|
|
"docs-html" folder you will find a table of disk sizes and geometries. Make a
|
|
note of the number of total SECTORS required for your desired hard disk size,
|
|
as well as the cylinders, heads and sectors per track (spt).
|
|
|
|
In DiskCopy, you need to choose "Custom..." from the menu of image sizes, and
|
|
choose to enter the size in "blocks" (on the Mac, a block is pretty much the
|
|
same as a sector). Then enter the number of total sectors you need.
|
|
|
|
Make sure the image is "Read/Write", not "Read Only", and make sure you have
|
|
entered the correct cyl=, heads= and spt= settings in your bochsrc file. Your
|
|
image file should now be accessible to Bochs.
|
|
|
|
You'll eventually need to use a utility like "fdisk" to make the image
|
|
readable.
|
|
|
|
- Step 3. Obtain a bootable PC floppy or floppy image.
|
|
You'll need to install an operating system in order to do anything useful
|
|
with Bochs. If you have installer floppies for a PC operating system (eg.
|
|
Windows or MS-DOS) you can use those. Otherwise you can download disk images
|
|
for FreeDOS or one of the many variants of Linux.
|
|
|
|
MacBochs now supports real PC floppy disks. To use the Mac floppy drive
|
|
instead of a disk image, use the special filename "[fd:]" in the appropriate
|
|
line of your bochsrc.
|
|
|
|
- Step 4. Set up your bochsrc file.
|
|
You set up your Bochs preferences by editing the "bochsrc" file. You'll need
|
|
to set up your bochsrc to work with your floppy and hard disk images, as well
|
|
as telling Bochs how many megs of PC RAM you want.
|
|
|
|
Problems
|
|
--------
|
|
|
|
There are some so far unresolved problems in the "macintosh.cc" GUI file:
|
|
|
|
- Keyboard support is VERY rudimentary; ie. it only supports alphanumerics
|
|
and a couple of special keys like Enter. The keyboard-related code is full of
|
|
holes and I'm going to completely rehash it.
|
|
|
|
- Mouse support hasn't been tested, but probably isn't fully working either.
|
|
|
|
|
|
Other Issues
|
|
------------
|
|
|
|
- The Mac port uses a ready-made config file (configmac.h), like the Win32
|
|
port used to. Macs are pretty homogeneous, so the settings should be
|
|
appropriate for most machines.
|
|
|
|
- The Mac port has an extra source file: "macutils.c" (with header file
|
|
"macutils.h"), which is used for Mac floppy drive support, among other
|
|
things.
|
|
|
|
- Like the Win32 port, the Mac port expects the "bochsrc" file to be in the
|
|
same directory as the Bochs application.
|
|
|
|
- Be sure to use Mac pathname conventions when editing the bochsrc file (ie
|
|
':' instead of '/' or '\').
|
|
|
|
|
|
New files
|
|
---------
|
|
|
|
The following are new, Mac-specific files:
|
|
|
|
gui/macintosh.cc
|
|
configmac.h
|
|
macutils.h
|
|
macutils.c
|
|
Bochs.proj
|
|
|
|
|
|
Changed Files
|
|
-------------
|
|
|
|
The following files from the main bochs distribution have been modified to
|
|
compile properly on the Mac:
|
|
|
|
bochs.h
|
|
main.cc
|
|
memory/memory.cc
|
|
memory/misc_mem.cc
|
|
iodev/floppy.cc
|
|
iodev/harddrv.cc
|
|
|
|
The changes are just conditional compilations which won't affect other
|
|
platforms (search for "#ifdef macintosh" and "#ifndef macintosh" if you want
|
|
to see what the changes are). These changes will need to be integrated into
|
|
the main distribution if the MacOS port is going to go ahead seriously.

WinNT4 guest network problems
|
|
|
|
From: Jeremy Wilkins <jeb at jeremywilkins.freeserve.co.uk>
|

To: bochs-developers@lists.sourceforge.net
|
|
Subject: [Bochs-developers] Odd network errors with NT4 Guest OS
|
|
|
|
I'm having trouble transferring files over the network to the guest OS
|
|
(NT4 SP1). If I'm using SMB then the it errors out early on with a
|
|
session cancelled. The file is 36Mb (SP6). I've tried with various file
|
|
sizes, 3Meg files work, 5 meg files do not.
|
|
|
|
I've also tried shuffling the files over http with similar problems,
|
|
small files are fine (can browse websites) but large files just error out.
|
|
|
|
The system is a 1Ghz Windows XP SP1 box with bochs 2.02, guest OS is
|
|
allocated 64Mb of RAM and running Windows NT4 SP1.
|
|
|
|
Any clues, anyone experiencing similar problems?

Did you try with a big IPS? start the guest clock applet and try to get
|
|
a more or less accurate time, with 1 Ghz should be in the 50 000 000 range.
|
|
IIRC NT timeout and abort before it send the whole packet.

Thanks, 60 000 000 seems to have done the trick (I can copy sp6 across
|
|
anyway). My original guess of 4000000 IPS was probably a bit low :)

|

thanks again

TAP under FreeBSD
|
|
|
|
Date: Fri, 14 Feb 2003 02:12:38 +0100
|
|
From: Ronald Klop <ronald at echteman.nl>
|
|
To: bochs-developers at lists.sourceforge.net
|
|
|
|
I've made eth_tap.cc working under FreeBSD 4.7, because the fbsd network driver
|
|
didn't work for me.
|
|
It's not a very clean patch, but the changes are minimal.
|
|
|
|
Some notes:
|
|
- I found that some of the includes aren't used at all (on FreeBSD).
|
|
- The socket which is created before /dev/tap0 is opened doesn't work, because
|
|
tap0 is created after opening the device.
|
|
- Maybe the eth_tap device can use a configure script like the eth_tuntap
|
|
device, because the device must be configured after opening.
|
|
- The padding of the ethernet frame with 2 bytes isn't needed in FreeBSD.
|
|
- I didn't do any work to check for this in configure, because I don't know how
|
|
configure works and don't have the time work it out now.
|
|
- the guest os must set (maybe this can be documented somewhere):
|
|
kldload if_tap (if tap is not compiled in the kernel)
|
|
ifconfig tap0 inet 10.0.1.1 netmask 255.255.255.0
|
|
sysctl net.inet.ip.forwarding=1
|
|
sysctl net.link.ether.inet.proxyall=1
|
