# DOS

You must read the message regarding software licenses in the Section called Third Party Software Licensing and Temporary Files in Chapter 1 before you install or use MS-DOS, OS2, DR-DOS, or any other DOS as a guest OS in Bochs.

## Accessing your CDROM

To access your CDROM in DOS, you must download an IDE CDROM driver. Bochs emulates a very generic CDROM drive, and several drivers are known to work. Others don't. This section describes how to set up your `config.sys` and `autoexec.bat` to enable the CDROM.

The drivers that have been reported to work are `OAKCDROM.SYS` that comes with several versions of Windows and `SBIDE.SYS` version 1.21 from Creative Labs[1] and OAKCDROM.SYS that comes with several versions of Windows. Copy the driver to your boot disk, and then set up the startup files as follows.

    config.sys:
      device=himem.sys
      device=oakcdrom.sys /D:CD001
          -or-
      device=sbide.sys /D:CD001 /P:1f0,14,3f6

    autoexec.bat:
      mscdex.exe /M:10 /D:CD001

If the files mentioned in `config.sys` and `autoexec.bat` are not in the root directory, give the full pathname, like `c:\windows\himem.sys`.

### Notes

[1] | To get it, go to Creative Labs web site, click on Support, then click Download Files. You get to a screen where you must select the operating system and the product for which you want the driver. Choose DOS as the operating system, and "CD-ROM: 4x and above" as the product. There are several choices, but you want `sbide121.exe` from April 15, 1997. Version 2.0 does not work. The download file is a self-extracting ZIP file, so on DOS or Windows you just run it; on other platforms you can try using the unzip command. The driver is called SBIDE.SYS.
