Use the Windows Explorer to findc:\bochs\dlxlinux\start.bat, and double-click start.bat. This will launch twowindows: one is the Bochs Display window, and the other is text window thatshows Bochs log messages. Normally the display window is the most interesting, but if something goes wrong the log messages should givean idea of what has happened. You may notice that your mouse pointer hasdisappeared into the Bochs Display window. Press F12 to get the cursor back.<br><br>Meanwhile, the Bochs display screen looks like a PC booting, and in fact it is!Bochs begins simulating a PC from the time the power turns on. You will seethe VGA BIOS message, and it begins loading Linux from the disk image. (Thedisk image is just a big file that Bochs uses as if it were a real hard drive.)After a while, you see Linux boot messages and eventually a login prompt. Youare now running Linux in a window!<br><br>Bochs simulates every instruction of an x86 CPU, so it is very memory- andcompute-intensive. The speed of your real CPU will make a big difference inhow fast the DLX Linux image boots. On a 750MHz Pentium, the sample Linux image takes about 25 seconds to boot.<br><br>Booting is complete when you see "dlx login:" and a cursor. At this loginprompt, type "root". On UNIX systems, root is the system admin user.There is no password for root on this image, so it lets you log in immediately. Now you should see a UNIX prompt, and you can begin totype UNIX commands.<BR><br><center><table border=1><td><PRE> Welcome to DLX V1.0 (C) 1995-96 Erich Boehm (C) 1995 Hannes Boehm dlx login: <b>root</b> Linux 1.3.89. dlx:~# <b>pwd</b> /root dlx:~# <b>cd /</b> dlx:~# <b>ls</b> bin/ etc/ lost+found/ root/ usr/ boot/ fd/ mnt/ sbin/ var/ dev/ lib/ proc/ tmp/ zip/ dlx:/# <b>df</b> Filesystem 1024-blocks Used Available Capacity Mounted on /dev/hda1 10060 2736 6005 29% / dlx:/# _</PRE></td></table></center><br>One thing you may notice is that the screen saver turns on (screen goesblank) very quickly when you have stopped typing. The reason is that Bochsalways simulates as fast as it can. If the CPU is very busy (runninginstructions nonstop), simulated time goes by slowly. If the CPU is idle (justwaiting for you to type, for example), simulated time speeds up dramatically.In any case, If the screen saver blanks out the screen, just press a key (tryshift or control) to restore the screen.<br><br>When you get tired of playing with UNIX, just type "reboot" to shutdown the Linux operating system. You can also press the "Power" button to stop the simulation.<br><br>In this brief introduction you saw how Bochs can boot and run an x86 operatingsystem in a window. It doesn't have to be Linux, of course! Various peoplehave been able to install and run DOS, Windows 3.1, Windows 95, Windows 98,Windows NT, Linux, FreeBSD, NetBSD, OpenBSD, and probably others that we'venever even heard of. In fact Bochs is used by many operating system developersto test out their software in a controlled environment without having toreboot their development machine.<br><br><a name="tools"><BR><font face="arial, helvetica" color="#1e029a" size="4"><b>What tools are included in this package?</b></font><BR>There are two tools for win32: bximage and sb16ctrl. <br><br><font face="arial, helvetica" color="#1e029a" size="3"><b>bximage</b></font><BR>Bximage is a small program that helps to create empty floppy disk and hard disk images. To use it, you should run bximage in an MSDOS window.(You could also double-click on it, but then you won't be able to read the lastfew lines of output before the window disappears.) Just CD to the directorywhere you want the disk images to go, and run bximage. Bximage will ask yousome questions about what type of disk image you need, and then create one foryou. <br><br>Here is an example run of bximage, in which I made a 12-meg hard disk image called c.img. The default answer to a question is always printed in brackets.If you want to accept the default choice, you can just press return. Also,you can always quit bximage by pressing Control-C.<br><br> <table align=center border=1><td><pre>c:\bochs> <b>bximage</b>======================================================================== bximage Disk Image Creation Tool for Bochs========================================================================Do you want to create a floppy disk image or a hard disk image?Please type hd or fd.

You can also change it to diskdif you already have a diskc line, but be careful not to have bothdiskd and cdromd--these options cannot be used together.<br><br><font face="arial, helvetica" color="#1e029a" size="3"><b>sb16ctrl</b></font><BR>The other tool for windows is called sb16ctrl, and it is used to configurethe Bochs emulated sound blaster.
