I suggest you try Luc Verhaegen's cool bios_extract utility instead. You
will find it in his git repository:
http://cgit.freedesktop.org/~libv/bios_extract/

What might help is to do
$ dd if=hdamg217.rom of=hdama.rom bs=512k count=1

This cuts away the Phoenix BIOS flash description at the end and leaves
you with the image only.

I tried with the latest version of bios_extract and applied the
following patch, and I was able to extract all modules:



./bios_extract hdama.rom

Then I used "romheaders" from the FCode Suite:
http://www.openfirmware.info/FCODE_suite to check the resulting
oprom_?.rom files and found the first one is it:

$ romheaders oprom_0.rom
