Hey
@Tumbleweed , I just used your instructions on a 2GB CF card in an A600 and they worked first time.
Here's the details for anyone else trying to replicate and might have issues.
DH0: OS3.1, non-bootable, FFS, 100MB
DH1: OS3.2.3, bootable, FFS, 100MB
DH2 and DH3: non-bootable, PFS\03, 800MB each. I used Quick Format and the HDInstTools that came with 3.2.3.
Mostly Stock A600: Has a 3.2 ROM and 8MB of Fast.
