    </entry>
  </row>
  <row>
    <entry>Floppy disk</entry>
    <entry>Yes</entry>
    <entry>Supports floppy disk images on all platforms: 2.88M 3.5", 1.44M 3.5", 1.2M 5.25", and 720K 3.5".  
    On Unix and Windows XP/NT/2000, Bochs can access the physical floppy drive.
    </entry>
  </row>
  <row>
    <entry>Multiple ATA channels</entry>
    <entry>Yes</entry>
    <entry>Emulates up to 4 ATA channels. Up to 8 ATA/ATAPI emulated devices can be attached,
    two per ATA channel.
    So you can have eight hard disks or seven hard disks and a CD-ROM or four hard
    disks and four CD-ROMs, or one hard disk and seven CD-ROMs, etc...
    </entry>
  </row>
  <row>
    <entry>Hard disk</entry>
    <entry>Yes</entry>
    <entry>Emulates ATA-2/IDE hard drives via image files.  Physical
    hard disk access is supported on some architecture, but NOT recommended, primarily for safety reasons.  
    Hard disk up to 32GB are supported, on any platform that support large files access. 
    </entry>
  </row>
  <row>
    <entry>CD-ROM</entry>
    <entry>Yes</entry>
    <entry>Emulates ATAPI-4/IDE CD-ROM.  The CD-ROMs can read from an ISO disk image
    on any platform. On Windows (9x/ME/NT/2000/XP), Linux, SunOS, FreeBSD,
    NetBSD, OpenBSD, Amiga/MorphOS, MacOSX and BeOS, Bochs can read from the
    physical CD-ROM drive. Starting with version 1.4, Bochs is even able to boot from
    a bootable CD or bootable ISO image.
    </entry>
  </row>
  <row>
    <entry>Keyboard</entry>
    <entry>Yes</entry>

    </entry>
  </row>
  <row>

  <row>
    <entry>Sound Blaster</entry>
    <entry>Yes</entry>
    <entry>Emulates a Sound Blaster 16 card. On Windows, Linux, FreeBSD, MacOS 9 and
    MacOSX, the output can be sent to the host computer's sound system, see
    <xref linkend="sb16-emulation"> for details.
    </entry>
  </row>
  <row>
    <entry>Network card</entry>
    <entry>Yes</entry>
    <entry>Emulates an NE2000 compatible network card.  On Windows NT/2000,
    Linux, FreeBSD, and NetBSD, Bochs will forward packets to and from the
    operating system so that the guest OS can talk on the physical network.
    Unfortunately, on some platforms the guest OS can talk to any machine on
    the network BUT NOT the host machine.  On Windows and on systems that
    allow the TAP or TUN/TAP interface, there is no such limitation.  Often
    the host machine may be configured so the guest OS has access to the
    internet. On MacOSX, you may download the TUN driver from:
    <ulink url="http://chrisp.de/en/projects/tunnel.html"></ulink>
    </entry>
  </row>
  <row>
    <entry>Parallel Port</entry>
    <entry>Yes</entry>
    <entry>Parallel port emulation was added by Volker Ruppert for Bochs 1.3.
    Data that is sent to the parallel port by the guest OS can be saved into a
    file or sent directly into the parallel port device (Unix only).
    </entry>
  </row>
  <row>
    <entry>Serial Port</entry>
    <entry>Yes</entry>
    <entry>The serial port (single 16550A UART emulation) is usable, on GNU/Linux,
    NetBSD, OpenBSD, FreeBSD and MacOSX as host and guest. On other OSes the
    emulation is present, but the connection to hard- or software of the host is
    not implemented yet. Up to 4 ports are available.
    </entry>
  </row>
  <row>
    <entry>Gameport</entry>
    <entry>Yes</entry>
    <entry>Emulates a standard PC gameport. The connection to a real joystick is
    currently supported on Linux and win32 only.
    </entry>
  </row>
  <row>
    <entry>PCI</entry>
    <entry>incomplete</entry>
    <entry>Emulates most of the i440FX PCI chipset. The Host-to-PCI bridge
    (PMC/DBX), the PCI-to-ISA bridge and the PCI IDE controller (PIIX3) are
    available. For PCI cards there are 5 PCI slots supported. PCI IDE currently
    does not support Busmaster-DMA.
    </entry>
  </row>
  <row>
    <entry>USB</entry>
    <entry>incomplete</entry>

  </row>
  <row>
    <entry>Dynamic Translation/Virtualization</entry>
    <entry>No</entry>
    <entry>Because Bochs is designed to be portable, it does not attempt
    to do any dynamic code translation or virtualization. See
    <xref linkend="whatisbochs"> for details.
    </entry>
  </row>
  <row>
    <entry>Simulate a Multiprocessor</entry>
    <entry>Yes</entry>
    <entry>Bochs can be configured to simulate up to 15 processors.  This
    feature is still experimental, but it can boot Linux 2.2 kernels with SMP
    support.  Please note that this does NOT mean that Bochs can run
    faster on a physical SMP machine.
    </entry>
  </row>
  <row>
    <entry>Take advantage of your SMP box</entry>
    <entry>No</entry>
    <entry>At present, Bochs does not use threads or parallel processing, so it
    will not run any faster on multiprocessor hardware.
    </entry>
  </row>
  <row>
    <entry>Copy and Paste</entry>
    <entry>Yes</entry>
    <entry>Text-mode screen text
    can be exported to the clipboard. Text in the clipboard can also be pasted, through Bochs,
    to the guest OS, as simulated keystrokes.
    </entry>

      <entry>Unix/X11</entry>
      <entry>
        X windows has always been well supported because it was
        Kevin Lawton's main development platform. Bryce Denney maintains
        the Unix/X11 platform now. Most features and fixes (not all) are
        tried first in Unix and then ported to the others; see
        <xref linkend="compiling"> for compile instructions.

      <entry>Win32</entry>
      <entry>
        This port was done by David Ross and is now maintained by
        Don Becker. You can compile with Microsoft Visual C++ 5.0 or 6.0,
        see <xref linkend="compiling-win32"> for compile instructions,
        or Cygwin, see <xref linkend="compile-cygwin">.

      <entry>BeOS</entry>
      <entry>
        Kevin Lawton wrote this port, originally to R3/PPC using
        CodeWarrior. It now works on R4/x86 with egcs. Simon Huet picked up
        maintaining/reworking the BeOS GUI port. In September 2001, Bernd Korz
        of Yellow Tab, Inc.
        (<ulink url="http://www.yellowtab.com">www.yellowtab.com</ulink>), took
        over the BeOS/Zeta port, and is working on raw CD-ROM and raw floppy
        support. For compiling, see <xref linkend="compile-beos">.
