 .SH OPTIONS
 .TP
-\fB-\-builtin=\fR\fImodule\fR
-Act as if \fImodule\fR is built into the kernel being used. \fBmkdumprd\fR
-will not look for this module, and will not emit an error if it does not
-exist. This option may be used multiple times.
-
-.TP
-\fB-f\fR
-Allows \fBmkdumprd\fR to overwrite an existing image file.
-
-.TP
-\fB-\-fstab=\fR\fIfstab\fR
-Use \fIfstab\fR to automatically determine what type of filesystem the
-root device is on. Normally, \fB/etc/fstab\fR is used.
-
-.TP
-\fB-\-image-version
-The kernel version number is appended to the initrd image path before the image
-is created.
-
-.TP
-\fB-\-nocompress
-Normally the created initrd image is compressed with \fBgzip\fR. If this
-option is specified, the compression is skipped.
-
-.TP
-\fB-\-omit-lvm-modules 
-Do not load any lvm modules, even if /etc/fstab expects them.
-
-.TP
-\fB-\-omit-raid-modules 
-Do not load any raid modules, even if /etc/fstab and /etc/raidtab expect them.
-
-.TP
-\fB-\-omit-scsi-modules 
-Do not load any scsi modules, including 'scsi_mod' and 'sd_mod'
-modules, even if they are present.
-
-.TP
-\fB-\-preload=\fR\fImodule\fR
-Load the module \fImodule\fR in the initial ramdisk image. The module gets
-loaded before any SCSI modules which are specified in \fI/etc/modprobe.conf\fR.
-This option may be used as many times as necessary.
-
-.TP
-\fB-v\fR
-Prints out verbose information while creating the image (normally
-the \fBmkdumprd\fR runs silently). 
-
-.TP
-\fB-\-version\fR
-Prints the version of \fBmkdumprd\fR that's being used and then exits.
