Steps for Multi boot:
1) Flash Kernel v1.7+
2) Go to CWM Recovery -> Multiboot -> Backup ROM.
3) Backup your Current ROM to ROM1 (It will backup the system.img at /sdcard/Android/data/g3mod/romname_ROM )
4) Add the system.img of your 2nd ROM to /sdcard/Android/data/g3mod/romname_ROM and similarly for different ROM's.
5) Use the CWM Recovery -> Multiboot -> Switch ROM option to switch between different ROM's.
Note: Ask the developer of the ROM's to provide you with the system.img for their ROM

Steps for Changing the Max Freq(Dynamic OC):
There is an entry in /sys/devices/system/cpu/cpu0/cpufreq/plls_table where you can put your own value for APLL.
Before doing this, set "PERFORMANCE" governor on and min and max frequencies to the maximum.
// Do this in adb
echo "0 a2580301 a14d0303 c07e13fc cf850240" > /sys/devices/system/cpu/cpu0/cpufreq/plls_table
You need to replace the 258(Hex Value) with your desired value.
Here 258 means
(2*16*16) + (5*16) + 8 = 600
and 3 means it is 600*2 = 1200
Therefore, a2580301 means 1200MHz.
This is a temporary method. For a permanent Method, add this line to a init.d script. Name the script to something like S10_Dyanmic_OC.
If you calculate a Hex Value for a particular frequencies add it here:
