A question about the /dev/ide

Dear all:
  I had use the UPM of MPC8270 to create the device driver of my pcmcia =
CF card.=20
  How to create the "/dev/hda" device nodes? I had only "/dev/ide" =
device nodes, I want to use command like  "mkswap /dev/hda4".
  When I use "mkswap /dev/ide/host0/bus0/target0/lun0/part1p4", it shows =
the "No such file or directory" message. How can I create=20
  the right device nodes? thanks!


 When it booted, it showed the following message:

 When using "fdisk -l" it shows the following message:

Just an idea: There are IDE-to-CF adapters and PCI-IDE adapters with working drivers.
(for evaluation)

How to create the "/dev/hda" device nodes? I had only "/dev/ide" device nodes,
I want to use command like  "mkswap /dev/hda4".
When I use "mkswap /dev/ide/host0/bus0/target0/lun0/part1p4",
it shows the "No such file or directory" message. How can I create 
the right device nodes? thanks!

man mknod?

But maybe you want to read some more things about devfs, udev, ... /etc/devfsd.conf
before you know what you are doing there?
Well... all that depends on your kernel/system config a bit...

Best greets,
