OK,
I finally found how to get these addresses. the /proc/pci returns the
following
RAID bus controller: Promise Technology, Inc. PDC20276 IDE (rev 1).
IRQ 10.
Master Capable. Latency=32. Min Gnt=4.Max Lat=18.
(A) I/O at 0xd000 [0xd007].
(B) I/O at 0xd400 [0xd403].
(C) I/O at 0xd800 [0xd807].
(D) I/O at 0xdc00 [0xdc03].
I/O at 0xe000 [0xe00f].
Non-prefetchable 32 bit memory at 0xeb010000 [0xeb013fff].
If I understand correctly from this guy
http://www.geocities.com/ender7007/index.html#2a
ide2=A,B+2 ide3=C,D+2
this makes
ide2=0xd000,0xd402 ide3=0xd8000,0xdc02
I boot and still nothing on fdisk -l /dev/ataraid/d0
What I failed on was creting the inir-rd. For some reasons I had to copy the
source from usr/src to /lib/modules. It didn't show RAID or PDC but could
that be because they are not module but compiled in the kernel?
Thanks again and sorry to be a pain.

Yoram,
On my box, fdisk -l /dev/ataraid/d0 gives :
Disk /dev/ataraid/d0: 255 heads, 63 sectors, 4866 cylinders
Units = cylinders of 16065 * 512 bytes

I suspect that you are missing the kernel append lines for ide settings:
ide2=0xd800,0xdc02 ide3=0xe000,0xe402
This might be different for your particular board (probably not though)
so check the HOWTO for how to get those values - anyone using a
different mobo or add-in card should check the values! If those are ok,
then ataraid and pdcraid should know where the controller lives, and be
able to use it. Start by adding the append line, then reboot, load the
raid modules and see what happens.
To make the initrd image (if you don't have compiled-in drivers), just
cd /boot, then run:
mkinitrd -v <your new image name> <the kernel you are using>
Watch the output for what modules it's using, and if pdcraid and ataraid
aren't there, do it again, but tell it which modules to add using the -m
switch (I think - I'm not using RH, but mkinitrd -h will tell you what
to use). Once that's made, you can edit lilo.conf, or grub.conf, to use
the new initrd.
This should all work with the standard 2.4.18 kernel, but 2.4.19 should
give better performance.
For your reference:
Here's my /etc/fstab - I use LVM, so where I have /dev/system/usr, you
might have /dev/ataraid/d0p3 or something.
