Just an update - I tried two other 945-based motherboards: an ASUS and
a Gigabyte.  They both worked fine.

So I'll guess it's the BIOS.

A shame.

Interesting.

I've had some bad Compactflash in the past that didn't work in IDE mode due 
to the fact that they didn't allow master/slave selection (I am always the 
master!  I care not for your attempt to influence me by changing the state 
of a pin!), but your problem sounds very different.

Hmm...could you try using a cable?
Bus timing may be different without.

Otherwise, I'd think it's time to call Intel support, possibly try an 
adapter they recommend.

Thanks Rolf.

Standard IDE disk works fine.
3.3V and 5V settings on the adapter make no difference.
The CF-IDE converter plugs straight into the IDE slot (no cable).
Using the latest BIOS.
The adapter runs in master mode.

Not looking good :-(

Either.

Try hooking up a standard disk to verify that the IDE interface on the 
motherboard works at all. (Cable/Power/motherboard problems possible)

Did you play with the 5V/3.3V settings on the adapter?

If a std IDE disk works, then it could be a BIOS issue; I see Intel has 
a recent BIOS update, posted 4th of Aug 05; though I couldn't read the 
release notes.
http://www.intel.com/design/motherbd/tp/tp_bios.htm

Another BIOS thingy is that some Phoenix BIOS I came across won't talk 
to a slave device on it's own; it will rely on the master to query the 
slave at bootup, and in some situations this can be a problem.

One thing I have found is that CF cards are very sensitive to the IDE
cable that is used.  Quite often if the cable is the standard length
there will be errors.  The timing of the IDE interface can be changed
on the motherboard settings, default is usually Mode 4 which is the
fastest, if you use Mode 2 or 3, it will run a bit slower which can
help.

Johnny.

Thanks Rolf.   In this case none of the SanDisk, PNY and Lexar flash
cards support DMA.  They work on one Intel motherboard model (with a
CF-IDE adapter that works in some other motherboards I've tried), but
not this new 945 chipset one.

All the motherboards that work are similar (3GHz P4 or Athlon64
equivalent).  Only this model motherboard (so far) is failing.

Could this be a BIOS issue, or a hardware fault/feature?

FWIW, I recall an issue I had when the Sandisk started supporting DMA on 
their compact flash cards; the custom adapters I used then did not have 
DMA wired, but as the flashdisk reported DMA capability, the BIOS tried 
to use it and hung at boot.

(The workaround for me was a to use a utility from Sandisk to disable 
DMA on the compact flash device, until the adapters were fixed.)

What size CF?  One consideration is that the CF controller runs
Power-on test.  It might take longer to test the bigger chips.  If it
does not complete the test before the PC query the controller, it will
not be recognized.

On the other hand, it could be wiring problems with your adapter.  You
can try ours with 32M CF as boot device and mount your 256M or bigger
CF.  We provide full refund if it does not work for you.

That's the problem - this motherboard is not recognizing the card at
all.

This is on an Intel D945GTP motherboard.  Out of the box, the BIOS does
not see the CF card.  The BIOS finds no bootable devices and no drives
are found when looking at the BIOS setup screens.

If I disable "Use Automatic Mode" in the Drive Setup in the BIOS it
hangs at the Intel splash screen.

I have tried SanDisk, Lexar and PNY CF cards.  All work in a different
Intel motherboard model (a D865GVHZ) but not in this one.

Suggestions welcome.

Paul.
