Hello,
how can I enable the DMA mode for CompactFlash cards on IDE?
When I try to set the key
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\PCI\Template\GenericIDE\DMA]
to 1, it is always reset to 0 after a reboot.
Sorry if this is a double post, but the matter is quite urgent.
Thanks in advance.

How do you set the DMA registry?
As this part of registry setting usually in boot.hv so it can't be
overwritten in runtime image but you need to change it (in your platform.reg
or project.reg) during building the OS image.

Hello,
thanks for your answer.
I did set it in the image (examining nk.bin, DMA is set to 1), but after
boot it is set to 0.
Do I need to set some other registry values in the PCI key?

If you are using hive based registry, ensure the registry you set in REG
file is enclosed by "; HIVE BOOT SECTION" and "; END HIVE BOOT SECTION"
tags.
Also, you can verify the %_flatreleasedir%\reginit.ini to see if it is
overwritten by others.

I verified both, and both are ok.
