I am in a very similar situation.  I can read and write to the DOC 2000 
tsop, but no luck booting to it.

This post by dwmw2 is relevant to our troubles:

My thinking is that GRUB is out, and doesn't currently work for INFTL 
devices.  I could be dead wrong.  My understanding is that normal grub 
needs to understand the filesystem it is loading the kernel from.  The 
patched grub understands NFTL, but not INFTL. 

I don't think that LILO has this limitation.  I think LILO just loads 
the kernel from a given address, it does not understand filesystems, so 
it may work.  I haven't tried LILO yet.
