For those who are keen to upgrade, virtual machines are their very favorite tools, because only some of the space on the hard disk, you can simulate a new "bare metal", hard drive, floppy drive, optical drive, sound card, network card Waiting for hardware devices, then completing hard disk partition, formatting, system installation, software trial, experience virus, etc. High risk operation - you don't have to worry about what is hurting on the system, because all this It's just a virtual world in the "hack of empire"! VMware, Virtual PC These two software is almost synonymous with the world of virtual machines, but they have very high requirements for system configuration. Not long ago, I saw the introduction of Bochs in the Linux Forum. It is said that it is not only not only not high, but also simulates Windows, Linux, UNIX and other operating systems, even better to download a operating system directly from the Bochs site. Mirror file! So hurry
http://sourceforge.net/projects/bochs
Download the Bochs installer, the latest version is 2.0.2. Of course, when downloading should pay attention to the selection platform (most users are Windows platforms), when the download is complete, execute the installation file, start the installation wizard, follow the prompts to step by step. Below, we will come to actually fight virtual system! Virtual minux system from
Http://sourceforge.net/project/ showfiles.php? group_id = 12580 && release_id = 135273
You can download the mirror file of many operating systems, but due to copyright restrictions, most of them are available herein to use the Linux, UNIX kernel, such as the famous FreeBSD, Freedos, Redhat Linux. Step 1 - Download the operating system The image file author downloads the mirror file file, download it back is a Gz format compressed file, size is 6.4MB, can be expanded with Winzip or WinRAR layer, then get bochsrc.txt, readme .txt, minix203.img 3 files, copy all of them to the Bochs installation directory. Step 2 - Redefining the use of the configuration file Bochs Different from other software, you need to configure the bochsrc.txt file to be used normally. If you direct BOCHS directly, you will prompt the error. Although we can refer to the Bochsrc-Sample.txt file in the installation directory, it is still very troublesome, and the author suggests everyone from
http://bochs.sourceforge.net/guestos/
Download a profile called debian-2.2r5.bochsrc.txt, rename it to bochsrc.txt, and copy it to the Bochs installation directory override the same name file, and then modify as follows. It should be noted that only the contents of the row without "#" when modifying, because the line "#" indicates that the line has been masked.
1 Change the location of the simulated BIOS file to find "Romimage: file = BIOS / BIOS-BOCHS-LATEST, Address = 0xF0000", which defines the location of the Bochs analog BIOS file. There is no BIOS in the BOCHS installation folder, but there is "Boos-Bochs-Latest" file, so we will change it here to "Romimage: File = Bios-Bochs-Latest, Address = 0xF0000". 2 Change the virtual memory configuration to find the line where "Megs: 32" is located, it indicates that the virtual system is assigned to 32MB memory. If you are less, you can add "#" on the lead, then choose a bigger memory, Of course, don't forget to delete the "#" of the lead. 3 Change the location of the simulated Vgabios file to find "Vgaromimage: BIOS / VGABIOS-ELPIN-2.40", based on the same reason, change it to "Vgaromimage: Vgabios-LGPL-LATEST". 4 Change the technical parameters of the virtual hard disk Since the Debian-Image specified in the standard configuration file as the mirror file of the hard disk, and we download the mirror image file, so you need to reconfigure it: Find "Diskc: file =" debian-image " , CYL = 1024, HEADS = 16, SPT = 63 ", will be modified to" file = "minix203.img", CYL = 95, Heads = 16, SPT = 63 ". The "minix203.img" here is the unzipped minux image file name. As for the following parameters such as CYL, Heads, SPT, you can run "Start → All Programs → Bochs 2.0.2 → Disk Image Creation Tool → HD", due to MiniX203 .img's file size is 46.8MB, so type 47 here, then press the two Enter key, the program will automatically create a mirror file called C.Img, we can find it from the bottom of the window shown in Figure 1 The above parameters. Step 3- Virtual Minix now runs the Bochs 2.0.2 program from the "Start" menu, open the main interface shown in Figure 2, because the relevant configuration has been completed in the Bochsrc.txt file, so we only need to press "5" can virtual minix operating system! Wait a moment, you can see the window shown in Figure 3, you can see the floppy disk, CD-ROM, Copy, Paste, Configuration, Reset, CD-ROM, Copy, Paste, Configuration, Reset, Power Supply, etc., look like a true Computer, you can experience the style of MINUX after logging in. Virtual Windows system If you want to install Windows Series operating systems in Bochs, you can't expect from
http://sourceforge.net/project/showfiles.php?group_id=12580&release_id = 135273
Download to the appropriate operating system image file, because the Windows series is a copyrighted business software. In addition, we must also configure BIOS, memory capacity, hard drive, boot mode, the main process is as follows: Step 1 - Specify the "Bios-Bochs-Latest" file in the BioCHS installation directory, and then "Romimage : File = bios-bochs-limited, address = 0xf0000 "This line content is added to the corresponding position. Step 2 - Allocate the "MEGS: 32" line in the Bochsrc.txt file, pay attention to the "#" character, this note that the memory size of the default configuration is 32MB, it is recommended to add one in the leader " # "Make mask, then" # "" # "," # ", headed" # ", is assigned 128MB of physical memory for the virtual system. Step 3 - Creating a virtual hard disk to create a virtual hard disk is still using "Start → All Programs → Bochs 2.0.2 → Disk Image Creation Tool → HD", then specify the capacity of the hard disk (unit is MB), the hard disk name (default is C ), When viewed to the corresponding parameters of Figure 1, it is added to the corresponding position of the BochSrc.txt file. Step 4 - Specify the boot mode from the Bochsrc.txt file to find the "Boot" section, which is specifically used to specify the startup medium, the default setting is "boot: c", which is from the hard disk boot system, "boot: CDROM" It is from the optical drive guide, you can modify it according to the actual situation, just delete the "#" of the corresponding line. However, if we use the optical drive to boot the system, we also need to remove "# cdrond: DEV = D:, Status = INSERTED", and re-specify the drive letter of the CD. Next, we can install the operating system on the virtual machine according to the normal manner. If you want to realize online interviews between virtual systems and host systems, you can

Download and install WinPCAP.
How, with Bochs free virtual machine tool, you can also play a deep linux, huh, huh.
