Re: A basic question regarding grub display options

This command notifies the memory manager that specified regions of RAM
ought to be filtered out (usually, because they're damaged). This remains in
effect after a payload kernel has been loaded by GRUB, as long as the loaded
kernel obtains its memory map from GRUB. Kernels that support this include
Linux, GNU Mach, the kernel of FreeBSD and Multiboot kernels in general.

Syntax is the same as provided by the Memtest86+ utility: a list of
address/mask pairs. Given a page-aligned address and a base address / mask
pair, if all the bits of the page-aligned address that are enabled by the
mask match with the base address, it means this page is to be filtered. This
syntax makes it easy to represent patterns that are often result of memory
damage, due to physical distribution of memory cells.


I didn't know about it but it seems useful. I would not remove it rather
leave it in the system. But wanted to know only, would play how it looks if
hidden?
