+.Dt BOOT.COM 8 i386
+.Os OpenBSD
+.Sh NAME
+.Nm BOOT.COM
+.Nd Boot an OpenBSD kernel from MS-DOS
+.Sh SYNOPSIS
+.Nm BOOT
+.Sh DESCRIPTION
+The
+.Nm
+utility, executed from an MS-DOS prompt, will load a kernel stored
+in the DOS partition, effectively booting OpenBSD. There are no
+command line arguments.
+.Pp
+.Nm
+functions identically to the standalone bootblocks, except that it
+only loads files on a DOS partition. After printing the `Boot:'
+prompt, there is a timeout of several seconds. If no key is pressed in
+that time, the default kernel
+.Em bsd
+is loaded from the root directory of the DOS C: partition.
+.Sh CAVEATS
+The file
+.Pa /usr/mdec/boot.com
+and a valid kernel file must be copied to the root directory
+of the DOS C: partition.
+.Pp
+If the desired FFS root filesystem is not on the first drive in the
+system, the
+.Fl r
+flag (use the kernel's compiled-in default root device)
+must be supplied when booting the kernel, i.e.:
+.Pp
+.Bd -literal -offset indent
+Boot: [[[wd(0,a)]bsd][-abcdrs]] : bsd -r
+.Ed
+.Sh BUGS
+.Nm
+will not load kernels compressed with
+.Xr gzip 1 ,
+or ramdisk kernels larger than 3M in size.
+.Pp
+.Nm
+always assumes the kernel is in the root directory of the DOS drive; to
+load a kernel from the current directory, the name must be entered at
+the `Boot:' prompt with no leading slashes.
+.Pp
+Loading a kernel from anywhere
+other than the root directory or the current directory is not supported.
+.Sh FILES
+.Pa /usr/mdec/boot.com
