cpia_pp= [HW,PPT]
Format: { parport<nr> | auto | none }
+ crashkernel=nn[KMG]@ss[KMG]
+ [KNL] Reserve a chunk of physical memory to
+ hold a kernel to switch to with kexec on panic.
+
cs4232= [HW,OSS]
Format: <io>,<irq>,<dma>,<dma2>,<mpuio>,<mpuirq>
Format: {"as"|"cfq"|"deadline"|"noop"}
See Documentation/block/as-iosched.txt
and Documentation/block/deadline-iosched.txt for details.
+ elfcorehdr= [IA-32]
+ Specifies physical address of start of kernel core image
+ elf header.
+ See Documentation/kdump.txt for details.
enforcing [SELINUX] Set initial enforcing status.
Format: {"0" | "1"}
i810= [HW,DRM]
+ i8k.ignore_dmi [HW] Continue probing hardware even if DMI data
+ indicates that the driver is running on unsupported
+ hardware.
i8k.force [HW] Activate i8k driver even if SMM BIOS signature
does not match list of supported models.
i8k.power_status
ips= [HW,SCSI] Adaptec / IBM ServeRAID controller
See header of drivers/scsi/ips.c.
+ irqfixup [HW]
+ When an interrupt is not handled search all handlers
+ for it. Intended to get systems with badly broken
+ firmware running.
+
+ irqpoll [HW]
+ When an interrupt is not handled search all handlers
+ for it. Also check all handlers each timer
+ interrupt. Intended to get systems with badly broken
+ firmware running.
+
isapnp= [ISAPNP]
Format: <RDP>, <reset>, <pci_scan>, <verbosity>
maxcpus= [SMP] Maximum number of processors that an SMP kernel
should make use of
+ max_addr=[KMG] [KNL,BOOT,ia64] All physical memory greater than or
+ equal to this physical address is ignored.
+
max_luns= [SCSI] Maximum number of LUNs to probe
Should be between 1 and 2^32-1.
irqmask=0xMMMM [IA-32] Set a bit mask of IRQs allowed to be assigned
automatically to PCI devices. You can make the kernel
exclude IRQs of your ISA cards this way.
+ pirqaddr=0xAAAAA [IA-32] Specify the physical address
+ of the PIRQ table (normally generated
+ by the BIOS) if it is outside the
+ F0000h-100000h range.
lastbus=N [IA-32] Scan all buses till bus #N. Can be useful
if the kernel is unable to find your secondary buses
and you want to tell it explicitly which ones they are.
