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.
