-.Dt COMPAT_IBCS2 8
-.Os
-.Sh NAME
-.Nm compat_ibcs2
-.Nd setup for running iBCS2 binaries under emulation
-.Sh DESCRIPTION
-.Ox
-supports running Intel Binary Compatibility Standard 2 (iBCS2)
-binaries.
-This only applies to i386 systems for now.
-Binaries are supported from SCO UNIX and other systems derived from UNIX
-System V Release 3.
-iBCS2 support is only well tested using SCO binaries.
-XENIX binaries are also supported although not as well tested.
-This option is controlled by the kern.emul.ibcs2
-.Xr sysctl 8 .
-SVR4 binaries are supported by the
-.Nm COMPAT_SVR4
-option.
-.Pp
-iBCS2 supports COFF, ELF, and x.out (XENIX) binary formats.
-Binaries from SCO OpenServer (version 5.x) are the only ELF binaries
-that have been tested.
-Most programs should work, but not ones that use or depend on:
-.Pp
-.Bl -tag -width 123 -compact -offset indent
-.It kernel internal data structures
-.It STREAMS drivers (other than TCP/IP sockets)
-.It local X displays (uses a STREAMS pipe)
-.It virtual 8086 mode
-.El
-.Pp
-The iBCS2 compatibility feature is active for kernels compiled with
-the
-.Nm COMPAT_IBCS2
-option enabled.
-If support for iBCS2 ELF executables is desired,
-the
-.Nm EXEC_ELF32
-option should be enabled in addition to
-.Nm COMPAT_IBCS2 .
-.Pp
-Many COFF-format programs and most ELF-format programs are dynamically
-linked.
-This means that the shared libraries that the program
-depends on will also be needed.
-Also, a "shadow root" directory for iBCS2 binaries
-on the
-.Ox
-system will have to be created.
-This directory is named
-.Pa /emul/ibcs2 .
-Any file operations done by iBCS2 programs run
-under
-.Ox
-will look in this directory first.
-So, if an iBCS2 program opens, for example,
-.Pa /etc/passwd ,
-.Ox
-will first try to open
-.Pa /emul/ibcs2/etc/passwd ,
-and if that does not exist open the `real'
-.Pa /etc/passwd
-file.
-It is recommended that iBCS2 packages that include
-configuration files, etc., be installed under
-.Pa /emul/ibcs2 ,
-to avoid naming conflicts with possible
-.Ox
-counterparts.
-Shared libraries should also be installed in the shadow tree.
-.Pp
-Generally, it will only be necessary to look for the shared libraries that
-iBCS2 binaries depend on the first few times
-iBCS2 programs are installed on the
-.Ox
-system.
-After a while, there will be a sufficient set of iBCS2 shared libraries
-on the system to be able to run newly imported iBCS2 binaries without
-any extra work.
-.Ss Setting up shared libraries
-How to get to know which shared libraries iBCS2 binaries need, and
-where to get them?
-Depending on the file type of the executable, there are different
-possibilities.
-(When following these instructions, root privileges are required
-on the
-.Ox
-system to perform the necessary installation steps).
-.Bl -tag -width 123
-.It 1. COFF binaries
-Simply copy all of the available shared libraries since they
-are fairly small in size.
-The COFF shared libraries are typically found in
-.Pa /shlib
-and can be obtained from the following sources:
-.Bd -unfilled -offset indent
-SCO UNIX version 3.x (aka ODT)
-SCO UNIX version 5.x (aka OpenServer)
-SCO UnixWare
-Many versions of SVR4.2/x86
-.Ed
-.Pp
-After copying the shared libraries, the following files should be
-present on the
-.Ox
-system:
-.Bd -unfilled -offset indent
-/emul/ibcs2/shlib/libc_s
-/emul/ibcs2/shlib/libnsl_s
-/emul/ibcs2/shlib/protlib_s
-.Ed
-.It 2. ELF binaries
-Copy all of the available shared libraries from the
-source system or distribution, or use the `ldd-elf' program (in
-development) to determine the libraries required by a specific binary.
-.Pp
-After copying the shared libraries, the following files should be
-present on the
-.Ox
-system:
-.Bd -unfilled -offset indent
-/emul/ibcs2/usr/lib/libc.so.1
-/emul/ibcs2/usr/lib/libcrypt.so
-/emul/ibcs2/usr/lib/libndbm.so
-/emul/ibcs2/usr/lib/libsocket.so.1
-.Ed
-.El
-.Pp
-If access to an SCO system is impossible, the extra files will need to be
-obtained from an SCO distribution.
-As of January 1998, SCO sells a copy of SCO OpenServer (iBCS2) and/or
-SCO UnixWare (SVR4) for personal/non-commercial use for only the cost
-of shipping (about $20US).
-The distribution comes on an ISO 9660-format CD-ROM which can be mounted
-and used to copy the necessary files.
-.Sh BUGS
-The information about SCO distributions may become outdated.
-.Pp
-Attempting to use a nameserver on the local host does not currently
-work due to an absurd shortcut taken by the iBCS2 network code
-(remember that there are no kernel sockets).
-.Pp
-16/32/64 bit offsets may not be handled correctly in all cases.
