+June 1999		  Kernel Parameters			v2.2.9
+			  ~~~~~~~~~~~~~~~~~
+
+The following is a consolidated list of the kernel parameters as defined
+in the file init/main.c and sorted into English Dictionary order (defined
+as ignoring all punctuation and sorting digits before letters in a case
+insensitive manner), and with descriptions where known.
+
+The text in square brackets at the beginning of the description state the
+restrictions on the kernel for the said kernel parameter to be valid. The
+restrictions referred to are that the relevant option is valid if:
+
+    APIC	APIC support is enabled.
+    APM 	Automatic Power Management support is enabled.
+    AX25	Appropriate AX.25 support is enabled.
+    CD		Appropriate CD support is enabled.
+    EIDE	EIDE/ATAPI support is enabled.
+    FB		The frame buffer device is enabled.
+    HW		Appropriate hardware is enabled.
+    ISDN	Appropriate ISDN support is enabled.
+    JOY 	Appropriate joystick support is enabled.
+    LPT 	Printer support is enabled.
+    MCA 	MCA bus support is enabled.
+    MDA 	The MDA console is enabled.
+    MOUSE	Appropriate mouse support is enabled.
+    NET 	Appropriate network support is enabled.
+    NFS 	Appropriate NFS support is enabled.
+    PARIDE	The ParIDE subsystem is enabled.
+    PCI 	PCI bus support is enabled.
+    PCMCIA	The PCMCIA subsystem is enabled.
+    PNP 	Plug & Play support is enabled.
+    PS2 	Appropriate PS/2 support is enabled.
+    RAM 	RAMdisc support is enabled.
+    SCSI	Appropriate SCSI support is enabled.
+    SERIAL	Serial support is enabled.
+    SMP 	The kernel is an SMP kernel.
+    SOUND	Appropriate sound system support is enabled.
+    VGA 	The VGA console has been enabled.
+    VT		Virtual terminal support is enabled.
+    XT		IBM PC/XT support is enabled.
+
+In addition, the following text indicates that the option:
+
+    BUGS=	Relates to possible processor bugs on the said processor.
+    KNL 	Is a kernel start-up parameter.
+
+Note that ALL kernel parameters listed below are CASE SENSITIVE, and that
+a trailing = on the name of any parameter states that that parameter will
+be entered as an environment variable, whereas its absence indicates that
+it will appear as a kernel argument readable via /proc/cmdline by programs
+running once the system is up.
