for the archvies/faq: how to get BOOT_IDE to work

[Andrew Kohlsmith]

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.  :-)

Regards,
Andrew

Greetings,

That looks like a feature that never got completed. The linker script
creates an array of configured streams, but hardwaremain is only looking
at the first stream in the array. I should have seen that in your
config! I probably missed it because I usually boot from ROM and the
config option looked 'natural in there'. Sorry about that.



G'day,
