Root BootManager Settings?

[JB3783]

Ok, I'm going to use BootManager for dual booting on my phone.
Here are the settings it's asking me for:

• 
  Device setting: I put HTC Kingdom
  sdcardblock: I have no clue what to put
  System size(In MB): No clue what to put here either
  Data size(in MB)itto
  Cache's size(In MB) Ditto

BootManager Pro - Play Store
That would be the app

I too am interested in being able to load 2 roms. I've heard of but never tried this app

Is this phone even supported? I learned the hard way u don't want to mess around with certain partions as u can deff wipe out something important.

I would strongly suggest checking out the developers website. It explains everything
