Common properties on GRUB

Jzarecta · 07-11-2007, 01:08 PM

I want to know which are the most common custom attributes that I will send through GRUB. Unfortunately I haven't need to do this very often so I lack which could be the most common knowledge of sending kernel parameters.

I would imagine that one would be the inird levels, also the ACPI and the explicit amount of RAM in case Linux doesn't detect it all.

But even then I am not sure of the convention in which the parameters need to be put on GRUB so it can get processed.

Any samples might help me a long way.

This may seem like splitting hairs, but I think what you are talking about is passing parameters to the kernel. All any bootloader does is pass these through at the time that the kernel is called. (I assume that this is not fundamentally different the passing parameters to ANY application.)

I would look at reference material for the kernel--and search Google for "linux kernel parameters" or maybe "linux kernel boot parameters"

Those aren't grub properties, they are kernel parameters. The kernel parameters are documented in the kernel source or documentation package for your distribution. The common ones are in the kernel-parameters.txt file. An online version for a 2.6.20 kernel is here.

Maybe I didn't explain correctly. Yes this are kernels parameters but you will pass it through the GRUB editor. When you type letter 'e' and edit the line that goes for the initrd.

So far I have found how to pass the runlevel and put the acpi.

I wonder what other parameters are common to pass through the grub editor.

All of them are listed in post #3.
