This may be obvious to the software authors, but to mere peons like myself this will save aggravation. :-)
In order to get BOOT_IDE to work, you must (obviously) "option BOOT_IDE=1" in the little-c config file.
However, from what I can gather, there can only be one stream configured. Streams are places to get elf images from: rom, tftp, ide, floppy and so on.
So "option BOOT_ROM=0" must be present, and further, "option USE_GENERIC_ROM=0" must also be present, or the rom stream is enabled, effectively removing the IDE stream. I think.
Perhaps Eric can elaborate a little bit, but with what I've written here I am able to have the IDE system initialized and used to get the ELF image to run. No actual kernel loading yet, but at least I am on the right track now. :-)
