Angelo,

I have looked at your problem again. I think you will not get
autodetection of available drives soon, but I have modified the pc386
BSP to make the used IDE interfaces configurable. See the attached patch.

Would you apply the attached patch to your RTEMS source tree and perform
a "bootstrap" to it?

After bootstrapping, you will have two options in the pc386 BSP:

- - the option IDE_USE_PRIMARY_INTERFACE is enabled by default, you should
disable it (set it to 0)
- - the option IDE_USE_SECONDARY_INTERFACE is disabled by default, you
should enable it (set it to 1)

These options are available in
"lib/libbsp/i386/pc386/include"bspopts.h", you can modify them there (in
your build directory tree), and maybe there is also some way to do this
in the "configure" tool, but I got no idea how this might be done...

With this configuration, the BSP should only try to access the secondary
IDE interface in your system.

I would be glad if things get better with this patch, it would be a
feasable solution for PR469 then.

wkr,
Thomas.
