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.
LP 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.
PPT Parallel port 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 MFM hard disk 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.

kbd-reset [VT]
load_ramdisk= [RAM]
lp=0 [LP] Specify parallel ports to use, e.g,
or lp=port[,port...] lp=none,parport0 (lp0 not configured, lp1 uses
or lp=reset first parallel port). 'lp=0' disables the printer
or lp=auto driver. 'lp=reset' (which can be specified in
addition to the ports) causes attached
printers to be reset. Using
lp=port1,port2,... specifies the parallel
ports to associate lp devices with, starting
with lp0. A port specification may be 'none'
to skip that lp device, or a parport name such
as 'parport0'. Specifying 'lp=auto' instead
of a port specification list means that device
IDs from each port should be examined, to see
if an IEEE 1284-compliant printer is attached;
if so, the driver will manage that printer.
ltpc= [HW]
mac5380= [HW,SCSI]
maxcpus= [SMP] States the maximum number of processors that
an SMP kernel should make use of.

no387 [BUGS=ix86] Tells the kernel to use the 387 maths
emulation library even if a 387 maths coprocessor
is present.
noapic [SMP,APIC] Tells the kernel not to make use of any
APIC that may be present on the system.
no-halt [BUGS=ix86]
noinitrd [RAM] Tells the kernel not to load any configured
initial ramdisc.
no-scroll [VGA]
nosmp [SMP] Tells an SMP kernel to act as a UP kernel.
optcd= [HW,CD]
panic=
parport=0 [HW,PPT] Specify parallel ports. 0
or parport=auto disables. Use 'auto' to force the driver
or parport=0xBBB[,IRQ[,DMA]] to use any IRQ/DMA settings detected
(the default is to ignore detected
IRQ/DMA settings because of possible
conflicts). You can specify the base
address, IRQ, and DMA settings; IRQ
and DMA should be numbers or 'auto'
(for using detected settings on that
particular port). Parallel ports are
assigned in the order they are
specified on the command line,
starting with parport0.
