HDtoolbox

[Darrin]

Here's a quick walkthrough:

Run HD Toolbox and prep the card.

Now Partition the card:
a.  Load the SFS file system.
b.  Select 2 partitions and adjust their sizes to match your requirements.
c.  For the first partition, make it bootable and change the file system from FFS (default) to SFS.
d.  Click on the second partition, change the file system to SFS (make it bootable with a lower priority if you wish).
e.  Save and Exit HDToolbox.

Restart the Amiga and quick format both partitions.

Consider formatting the CF card in your PC as FAT32 prior to putting it in the Amiga.  I had to do this with a CF card once when my Amiga simply refused to play ball with it.
