I think you can do it with a PC-Task hardfile but I'm not sure on that, and it takes some work. It'll also be a lot slower than a proper HD.
You could try Software Hut for the manual (
http://www.softhut.com/books.html lists it at $9.95) - I do have the manual but I don't want to sell it I'm afraid. If I get time I may be able to copy it but I'm very busy at the moment. I'm not sure it has anything that'll help anyway with your IDE problem... did you definitely enable IDE on the ISA card? Can you show us a screenshot of your machine running MSD on the IRQ page?
Does your HDD spin up correctly when the BB starts (it should stay powered down until janus.library is started)?
