RamrodXL testing in a 1200XL

Hi,

  I have a RamrodXL board in a 1200XL that I am testing.  I have it connected per instructions for the correct Antic chip that is installed.  I am getting it to boot to Basic without my Happy drive connected.

But as soon as I use Dos 2.5 and try to boot it gets to the Settingup Ramdisk screen and stops.  I'm not sure if it's the drive or something in the RamrodXL upgrade or the 1200XL.  

Is there a program or a cart that when booted confirms the extra memory is there and available?

Thanks
