Post Increasing the KERNEL parameter

Am trying to create a RAMDISK of 1 GB in a 2 GB RAM.

But it is only possible to create 512 MB RAMDISK.

While searching i found that it is possible to create 25% of RAM as RAMDISK.
We want to increase a kernel parameter to create a bigger RAMDISK


Will you please help me what to do ?

Which kernel configuration i need to change for this ??

and how could i change this ?

I think you need recompile kernel to increase ram disk size

If you write data in HDD it will take some time, instead of that you can write your data in RAM it will be much quicker. ( obviously when the system is switched OFF, you will loss data ). But i require this only for processing the data quickly.

I had a 2 GB RAM in my system, and i want to create a 1.5 GB RAMDISK, but i found it is possible only to create 25% of RAM as RAMDISK, to change this behaviour i need to change kernel parameter....

But i don't have any knowledge about that...

I think you could have understood this situation.
