Hey Guys,
Since there has been a new ram split created by the generous Dom, I have updated my Ram selector script to take it into account.
You can get the script from
Here (ad supported)
or
Here.
This adds support for the new ram split if you have it present. It also keeps the old 224/32 ram split if for some reason you still want to use that one.
Script below
#!/bin/bash
##
## Raspberry Pi Memory Split Selector Script v4
## Author: SirLagz
## Website: http://sirlagz.net
##
## The purpose of this script is to make selecting the memory split
## on the RPi easy.
## Simply make this script executable if it's not already, move
## it to the directory with the elf files, and run it with ./select4.sh
## The menu should be pretty self explanatory.
