+ acpi_dbg_layer= [HW,ACPI]
+ Format: <int>
+ Each bit of the <int> indicates an acpi debug layer,
+ 1: enable, 0: disable. It is useful for boot time

+ via /proc/acpi/debug_layer.

See also header of drivers/scsi/AM53C974.c.
Disable APC CPU standby support. SPARCstation-Fox does
not play well with APC CPU idle - disable it if you have
APC and your system crashes randomly.
+
+ apic= [APIC,i386] Change the output verbosity whilst booting
+ Format: { quiet (default) | verbose | debug }
+ Change the amount of debugging information output
+ when initialising the APIC and IO-APIC components.
apm= [APM] Advanced Power Management
See header of arch/i386/kernel/apm.c.
hd?= [HW] (E)IDE subsystem
hd?lun= See Documentation/ide.txt.
+ highmem=nn[KMG] [KNL,BOOT] forces the highmem zone to have an exact
+ size of <nn>. This works even on boxes that have no
+ highmem otherwise. This also works to reduce highmem
+ size on bigger boxes.
+
hisax= [HW,ISDN]
See Documentation/isdn/README.HiSax.
isapnp= [ISAPNP]
Format: <RDP>, <reset>, <pci_scan>, <verbosity>
+ isolcpus= [KNL,SMP] Isolate CPUs from the general scheduler.
+ Format: <cpu number>, ..., <cpu number>
+ This option can be used to specify one or more CPUs
+ to isolate from the general SMP balancing and scheduling
+ algorithms. The only way to move a process onto or off
+ an "isolated" CPU is via the CPU affinity syscalls.
+
+ This option is the preferred way to isolate CPUs. The
+ alternative - manually setting the CPU mask of all tasks
+ in the system can cause problems and suboptimal load
+ balancer performance.
+
isp16= [HW,CD]
Format: <io>,<irq>,<dma>,<setup>
so, the driver will manage that printer.
See also header of drivers/char/lp.c.
+ lpj=n [KNL]
+ Sets loops_per_jiffy to given constant, thus avoiding
+ time-consuming boot-time autodetection (up to 250 ms per
+ CPU). 0 enables autodetection (default). To determine
+ the correct value for your kernel, boot with normal
+ autodetection and see what value is printed. Note that
+ on SMP systems the preset will be applied to all CPUs,
+ which is likely to cause problems if your CPUs need
+ significantly divergent settings. An incorrect value
+ will cause delays in the kernel to be wrong, leading to
+ unpredictable I/O errors and other breakage. Although
+ unlikely, in the extreme case this might damage your
+ hardware.
+
ltpc= [NET]
Format: <io>,<irq>,<dma>
mga= [HW,DRM]
+ mousedev.tap_time=
+ [MOUSE] Maximum time between finger touching and
+ leaving touchpad surface for touch to be considered
+ a tap and be reported as a left button click (for
+ touchpads working in absolute mode only).
+ Format: <msecs>
mousedev.xres= [MOUSE] Horizontal screen resolution, used for devices
reporting absolute coordinates, such as tablets
mousedev.yres= [MOUSE] Vertical screen resolution, used for devices
noasync [HW,M68K] Disables async and sync negotiation for
all devices.
+ nobats [PPC] Do not use BATs for mapping kernel lowmem
+ on "Classic" PPC cores.
+
nocache [ARM]
nodisconnect [HW,SCSI,M68K] Disables SCSI disconnects.
noexec [IA-64]
+ noexec [i386]
+ noexec=on: enable non-executable mappings (default)
+ noexec=off: disable nn-executable mappings
+
nofxsr [BUGS=IA-32]
nohighio [BUGS=IA-32] Disable highmem block I/O.
nolapic [IA-32,APIC] Do not enable or use the local APIC.
+ noltlbs [PPC] Do not use large page/tlb entries for kernel
+ lowmem mapping on PPC40x.
+
nomce [IA-32] Machine Check Exception
+ noresidual [PPC] Don't use residual data on PReP machines.
+
noresume [SWSUSP] Disables resume and restore original swap space.
no-scroll [VGA] Disables scrollback.
noacpi [IA-32] Do not use ACPI for IRQ routing
or for PCI scanning.
+ firmware [ARM] Do not re-enumerate the bus but
+ instead just use the configuration
+ from the bootloader. This is currently
+ used on IXP2000 systems where the
+ bus has to be configured a certain way
+ for adjunct CPUs.

prompt_ramdisk= [RAM] List of RAM disks to prompt for floppy disk
before loading.
psmouse.rate= [HW,MOUSE] Set desired mouse report rate, in reports

psmouse.resetafter=

+ [HW,MOUSE] Try to reset the device after so many bad packets
+ (0 = never).
psmouse.resolution=
[HW,MOUSE] Set desired mouse resolution, in dpi.
psmouse.smartscroll=
This is actually a boot loader parameter; the value is
passed to the kernel using a special protocol.
+ vmalloc=nn[KMG] [KNL,BOOT] forces the vmalloc area to have an exact
+ size of <nn>. This can be used to increase the
+ minimum size (128MB on x86). It can also be used to
+ decrease the size and leave more room for directly
+ mapped kernel RAM.
