nofpu 
Can be used to disable the FPU entirely. In this the kernel FPU emulation will take over floating point processing. Useful if a FPU is known to be defective, has accuracy problems and wrongly detected as present even though none exists.
rd_start 
The base address of a loaded ramdisk image. This option was added in Linux 2.6.10-rc2. See also rd_start.
rd_base 
The size of a loaded ramdisk image. This option was added in Linux 2.6.10-rc2. See also rd_start.
console 
The console settings. When using this option, you will need to specify the serial console port and baud rate. For example: console=ttyS0,38400 where ttyS0 is the serial console port and 38400 is the baud rate for the serial port. Another example: console=ttyS0,384008N1 where 8 is is data bits, N is odd parity and 1 is stop bits.
