I do not know the specific details.
I have tried this as a master and as a slave with hard drives and it did
not work.
By them selves it worked in the master slot only.

Yes, but one important thing - The CF must be marked as a "Fixed disk"
type, and support the ATA standard. A lot of the CF out there is for use
in cameras, and will not master/slave properly. We use the Transcend
industrial CF media.

Hamilton - do you know where the compact-flash cards are deficient? I'm
guessing they could simply ignore the drive bit in the drive/head register
or be unaware of the SPSYNC/CSEL line that, if not used for
spindle syncronization, can provide an inter drive communication about
which is slave & which is master.
Just guessing though; if you have a more clear understanding, it
would be appreciated.

Does the slave jumper really work ??
Can you have a master thats a hard drive or another CF adapter ??
The ones I have used in the past did not do that correctly.

I think he's looking for a adapter that has a master/slave jumper setting.

They're about $15. We use them from time to time...

This is not the fault of the adapter.
The Compact flash cards do not know about master/slave, so it does not
have code to run that way.

comp.arch.embedded
compact-flash/ide adapter
A compact-flash/ide adapter (SD-CF-IDE-A) from dealextreme.com worked well
but only as a master, not as a slave, which is a distinct bother. Anyone know
of an ide adapter that works either way, either from dealextreme or another
dealer?
