Before compiling, you'll need to run the configure script, which will configure
source code to run
on your system, and with your chosen options. There are many
options to 'configure', and you probably don't need any of them.
If you run BeOS, specify '--with-beos' to configure.
To see a complete list:
unix-> ./configure --help
For more complete documentation of options available to configure,
click on this link.
You will also need to set environment variables to tell configure what compiler and options to use. Check out this link. It's the same as the one above.
Now run configure, be it manually or by way of a script file.
unix-> ./configure
-or-
unix-> ./.conf.x86
If the configure script bombs, check 'config.log'. Specifically, look for errors returned by the compiler. You may have options incompatible with your compiler. See the link on setting the environment variables above.
Assuming at this point all went well with the configure command, edit the file 'config.h', which was generated by ./configure. Look for the USER CONFIGURABLE OPTIONS section. Each parameter available for editing is documented. Generally the defaults are fine for typical users. Please read about each parameter and edit carefully. NOTE: This file is generated, and will be deleted if you run 'make dist-clean'.
You may now compile the source.
unix-> make
There are two options; you may install the VGA font in a global place, or in a local directory. You may need to install it locally if you don't have root access.
Option 1: installing VGA font in global font directory
# NOTE1: Make sure your DISPLAY variable points to local machine. # NOTE2: These steps require root privileges. # NOTE3: Your X11 fonts path will vary on different systems. For example: # Solaris 2.x /usr/openwin/lib/X11/fonts # Linux /usr/lib/X11/fonts/ root-> cp font/vga.pcf font-path-here/misc root-> compress font-path-here/vga.pcf root-> mkfontdir font-path-here/misc root-> xset fp rehashOption 2: installing VGA font in local font directory
# NOTE1: Make sure your DISPLAY variable points to local machine. # NOTE2: The "xset" command needs to be run for each X session. user-> mkfontdir bochs-YYMMDD/font user-> xset fp+ [full-path]/bochs-YYMMDD/fontHard Drive Image File: Bochs emulates a hard drive by using a large Unix file, which you must create. The size of the hard drive is dependent upon the number of cylinders, heads, and sectors-per-track that you would like to emulate. Here are some examples of possible drive geometries:
| Size | Cylinders | Heads | Sectors/Track | Sectors Total |
|---|---|---|---|---|
| 10MB | 306 | 4 | 17 | 20808 |
| 20MB | 615 | 4 | 17 | 41820 |
| 30MB | 615 | 6 | 17 | 62730 |
| 46MB | 940 | 6 | 17 | 95880 |
| 62MB | 940 | 8 | 17 | 127840 |
| 112MB | 900 | 15 | 17 | 229500 |
| 126MB | 256 | 16 | 63 | 258048 |
| 483MB | 1024 | 15 | 63 | 967680 |
| 504MB | 1024 | 16 | 63 | 1032192 |
unix-> dd if=/dev/zero of=112M bs=512 count=229500
Floppy Disk Image File: Bochs emulates a floppy drive/disk using either
a Unix file, or a real floppy drive Unix device. To use either, you will need
an entry in your '.bochsrc' file pointing to the regular or device file. Use
the 'floppya:' and 'floppyb:' directives. If you are starting out, you will
need to make a copy of an existing bootable floppy. Otherwise, you may create
a blank image file, if you intend on formatting it using the OS you boot
within Bochs.
| Size | Cylinders | Heads | Sectors/Track | Sectors Total |
|---|---|---|---|---|
| 0.720MB | 80 | 2 | 9 | 1440 |
| 1.2MB | 80 | 2 | 15 | 2400 |
| 1.44MB | 80 | 2 | 18 | 2880 |

To create a copy of an existing floppy disk, granted you have a floppy disk
drive on your workstation, you can use one of the following commands, where
'/dev/fd0' would be the path to your floppy drive device name.
NOTE: If your system uses a form of volume management to automount your floppy drive, you may have to tell it you popped in a new floppy, and use an alternative device name to access it.
# Linux, direct use of floppy drive using 'dd'
unix-> dd if=/dev/fd0 ibs=512 of=1.44M
--or--
# Linux, direct use of floppy drive using 'cp'
unix-> cp /dev/fd0 1.44M
--or--
# With Volume Management handling floppy drive
Solaris 2.x-> volcheck
Solaris 2.x-> dd if=/vol/dev/aliases/floppy0 ibs=512 of=1.44M

I need to look at this problem a little more.
Using Ctrl-h always seems to work for me.
