-.Os
-.Sh NAME
-.Nm i386_vm86
-.Nd set virtual 8086 processor registers and mode
-.Sh LIBRARY
-.Lb libi386
-.Sh SYNOPSIS
-.In sys/types.h
-.In signal.h
-.In machine/mcontext.h
-.In machine/segments.h
-.In machine/sysarch.h
-.In machine/vm86.h
-.Ft int
-.Fn i386_vm86 "struct vm86_struct *vmcp"
-.Sh DESCRIPTION
-.Fn i386_vm86
-will set the process into virtual 8086 mode using the registers and
-selectors specified by the context pointed to by
-.Ar vmcp .
-The processor registers are set from
-.Ar vmcp->substr.regs ,
-and the emulated processor type from
-.Ar vmcp->substr.ss_cpu_type .
-.Pp
-The kernel keeps a pointer to the context, and uses the tables stored at
-.Ar vmcp->int_byuser
-and
-.Ar vmcp->int21_byuser
-for fast virtual interrupt handling.
-If the
-.Ar n th
-bit is clear in the first of these arrays,
-then the kernel may directly emulate the real-mode x86 INT
-.Ar n
-instruction handling.
-If the
-.Ar n
-th bit is set, then the process is
-delivered a signal when an INT instruction is executed.
-.Pp
-Since MS-DOS puts many DOS functions onto interrupt 21, it is handled
-specially: the
-.Ar k
-th bit in the
-.Ar vmcp->int21_byuser
-array is checked when INT
-.Ar 21
-is requested and the
-.Ar ah
-register is
-.Ar k .
-.Sh RETURN VALUES
-This routine does not normally return: 32-bit mode will be restored by
-the delivery of a signal to the process.
-In case of an error in setting
-the VM86 mode, a value of \-1 is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-.Fn i386_vm86
-will fail if:
-.Bl -tag -width [EINVAL]
-.It Bq Er EFAULT
-The state at
-.Ar vmcp
-was not readable to the user process.
