DMA / PIO Mode problem

I have 2 HDs connected to a single IDE channel. The master HD (OS) is
running in Ultra DMA mode. The second is running in PIO mode despite having
selected the windows option to run the drive in DMA mode if possible.

My problem is that I believe that both drives should be able to run in DMA
mode - the master is a Seagate EIDE drive (I can't check further details
right now), the other an IBM Deskstar 60GXP - which being fairly new should
be able to run in DMA - but the automatic windows settings have put it into
PIO mode - so is there anything I can do?

I haven't discovered anywhere on the IBM (Hitachi) support website yet on
how to change the settings and the jumper setting diagram on the HD itself
doesn't specify any details on this (which I think drive makers should).

Anyone know if I can change this setting? Thanks in advance.
 
Did you check if your Bios is set correctly for it.

I have now - I still get same problem.

I read somewhere that if you change the BIOS settings to max values e.g.
Ultra DMA Mode 6 (on my motherboard at least) that the drives will work out
that they should be running at a different speed and change accordingly. If
the drives were set as a different mode previously and you have auto-detect
on in the BIOS then it takes the previous setting.

However, I noticed as the POST screen flashed past that the master had set
itself to Ultra DMA mode 5, and the slave did the same, yet still in my
windows settings with DMA if available, I'm getting PIO only on the slave
drive - which is very frustrating because I'm trying to send video across
the drives and the settings I'm lumbered with are stopping me from achieving
what I should get.
