Specifications

The `noisapnp' Argument
If ISA PnP is built into the kernel, this will disable it.
The `nomce' Argument
Some newer processors have the ability to self−monitor and detect inconsistencies that should not regularly
happen. If an inconsistency is detected, a Machine Check Exception will take place and the system will be
halted (rather than plundering forward and corrupting your data). You can use this argument to disable this
feature, but be sure to check that your CPU is not overheating or otherwise faulty first.
The `nosmp' Argument
Use of this option will tell a SMP kernel on a SMP machine to operate single processor. Typically only used
for debugging and determining if a particular problem is SMP related.
The `noresume' Argument
If software suspend is enabled, and a suspend to disk file has been specified, using this argument will give a
normal boot and the suspend data will be ignored.
The `notsc' Argument
Use of this option will tell the kernel to not use the Time Stamp Counter for anything, even if the CPU has
one.
The `nofxsr" Argument
Use of this option will tell the kernel to not use any speed−up tricks involving the floating point unit, even if
the processor supports them.
The `panic=' Argument
In the unlikely event of a kernel panic (i.e. an internal error that has been detected by the kernel, and which
the kernel decides is serious enough to moan loudly and then halt everything), the default behaviour is to just
sit there until someone comes along and notices the panic message on the screen and reboots the machine.
However if a machine is running unattended in an isolated location it may be desirable for it to automatically
reset itself so that the machine comes back on line. For example, using panic=30 at boot would cause the
kernel to try and reboot itself 30 seconds after the kernel panic happened. A value of zero gives the default
behaviour, which is to wait forever.
Note that this timeout value can also be read and set via the /proc/sys/kernel/panic sysctl interface.
The `pirq=' Argument
Using this option tells a SMP kernel information on the PCI slot versus IRQ settings for SMP motherboards
which are unknown (or known to be blacklisted). See linux/Documentation/IO−APIC.txt for more
information.
