.SH OPTIONS
.TP
-.B \-s
-Install a "safe, slow and stupid" version of \fBsyslinux\fP. This version may
-work on some very buggy BIOSes on which \fBsyslinux\fP would otherwise fail.
+\fB\-i\fP, \fB\-\-install\fP
+Install \s-1SYSLINUX\s+1 on a new medium, overwriting any previously
+installed bootloader.
+.TP
+\fB\-U\fP, \fB\-\-update\fP
+Install \s-1SYSLINUX\s+1 on a new medium if and only if a version of
+\s-1SYSLINUX\s+1 is already installed.
+.TP
+\fB\-s\fP, \fB\-\-stupid\fP
+Install a "safe, slow and stupid" version of \s-1SYSLINUX\s+1. This version may
+work on some very buggy BIOSes on which \s-1SYSLINUX\s+1 would otherwise fail.
If you find a machine on which the \-s option is required to make it boot
reliably, please send as much info about your machine as you can, and include
the failure mode.
.TP
-.B \-f
+\fB\-f\fP, \fB\-\-force\fP
Force install even if it appears unsafe.
.TP
-.B \-r
+\fB\-r\fP, \fB\-\-raid\fB
RAID mode. If boot fails, tell the BIOS to boot the next device in
the boot sequence (usually the next hard disk) instead of stopping
with an error message. This is useful for RAID-1 booting.
.TP
-\fB\-d\fP \fIsubdirectory\fP
+\fB\-d\fP, \fB\-\-directory\fP \fIsubdirectory\fP
Install the \s-1SYSLINUX\s+1 control files in a subdirectory with the
specified name (relative to the root directory on the device).
.TP
-\fB\-o\fP \fIoffset\fP
+\fB\-t\fP, \fB\-\-offset\fP \fIoffset\fP
Indicates that the filesystem is at an offset from the base of the
device or file.
+.TP
+\fB\-\-once\fP \fIcommand\fP
+Declare a boot command to be tried on the first boot only.
+.TP
+\fB\-O\fP, \fB\-\-clear-once\fP
+Clear the boot-once command.
+.TP
+\fB\-H\fP, \fB\-\-heads\fP \fIhead-count\fP
+Override the detected number of heads for the geometry.
+.TP
+\fB\-S\fP, \fB\-\-sectors\fP \fIsector-count\fP
