Running Bochs is easier if you use a configuration file (we call it <TT CLASS="FILENAME" >bochsrc</TT >). See <A HREF="x1387.html" >the Section called <I >bochsrc</I ></A > for all supported options.</P ><P >The easiest way to setup Bochs for the first time is to use the example configuration file called <TT CLASS="FILENAME" >bochsrc-sample.txt</TT >. Locate that file (location depends on the (host) OS and on the installation facility used) and copy it to a location where Bochs looks for that file, see <A HREF="x2479.html" >the Section called <I >Search order for the configuration file</I > in the Chapter called <I >Using Bochs</I ></A >.</P ><P >The next step is to change the configuration so that it fits your needs: You most likely want to setup a hard disk (see <A HREF="x3685.html" >the Section called <I >Using the bximage tool</I > in the Chapter called <I >Tips and Techniques</I ></A > and <A HREF="x1387.html#BOCHSOPT-ATA-MASTER-SLAVE" >the Section called <I >ata0-master, ata0-slave, ata1-*, ata2-*, ata3-*</I ></A >), and install some OS on it using either a set of floppy disks (see <A HREF="x1387.html#BOCHSOPT-FLOPPYAB" >the Section called <I >floppya/floppyb</I ></A >) or a CD-ROM (see <A HREF="x1387.html#BOCHSOPT-ATA-MASTER-SLAVE" >the Section called <I >ata0-master, ata0-slave, ata1-*, ata2-*, ata3-*</I ></A > again) as installation media. Make sure you boot the emulation from the media you want, using the right setting as <A HREF="x1387.html#BOCHSOPT-BOOT" >boot option</A >.</P ><P >If your keyboard output inside of Bochs is wrong, you may also need a keymap file to remap your keyboard layout to the U.S. layout. A set of keymap files for the X window system and SDL (Linux port) is distributed with Bochs. If your keyboard layout is not supported yet, you can create your own one by following the instructions given in <A HREF="x2052.html" >the Section called <I >How to write your own keymap table</I ></A >.</P ><P >A collection of disk images of different operating systems can be found at <A HREF="http://bochs.sourceforge.net/diskimages.html" TARGET="_top" >http://bochs.sourceforge.net/diskimages.html</A >.
