I should have fixed the build of the old IDE stack in r30671.
system/add-ons/kernel/busses/ata should never exist for the moment, it needs to
be busses/ide always, also for the new ATA stack.
When you toggle between HAIKU_ATA_STACK = 1 in your UserBuildConfig:
* When you do a clean build, you don't need to watch out for anything.
* When you "update-all" or copy files from a clean build onto an existing
installation, you need to watch out for system/add-ons/kernel/drivers/generic/:
It should be *only* ata_adapter for the new stack and *only* ide_adapter for
the old stack in there. Also you should have *only* one of
system/add-ons/kernel/bus_managers/ide or ata of course.
All this shows that the transition to the new ATA stack is really incomplete
right now. For the most part, the drivers in busses/ata, which are straight
copies from busses/ide right now, need to be adopted for busses/ata and any
changes in the ATA bus_manager if necessary. Then there is a
headers/private/drivers/ide_adapter.h, which needs to be changed too and there
are tons of *_IDE_* defines that need to be cleanup. On top of that the device
manager has some hard coded paths for busses/ide at the moment.
Last but not least, I don't know why my main system does not boot with the new
ATA stack. When it does boot, it uses the SATA/AHCI driver. It does have a
Marvel IDE chip and a CD-ROM attached to that. I used to be able to boot with
either the IDE stack or the new ATA stack before some recent changes.
Best regards,
