I have read some docs in the inet. I have understood what is initrd, how to use initramfs-tools debian package (in particular, update-initramfs command and "/etc/initramfs-tools/modules" file). I have being intended to add "blacklist ide-generic" string to "/etc/initramfs-tools/modules" file & to run "initramfs-tools -k $(uname -r) -u" command but when I opened this file I was shocked. That is I have seen:

# Added by Debian Installer

I decided simply delete this string from "modules" file (and update initrd then). And it has solved the problem!

I am glad to hear that you have DMA working now.
Nevertheless, I don't understand why Debian Installer add this ill-started module to "/etc/initramfs-tools/modules" file. Seems the bug to be Debian-specific.

If the information on the Debian driver check page is correct, i.e. if
you really need kernel 2.6.25 for the amd74xx module to work with your
controller, then it may be reasonable to add ide_generic to /etc/modules
to reduce the risk of the system not booting at all. (The installer has
kernel 2.6.24.) However that may be, please send an installation report
to the Debian installer team, describing your problems.

Now I'm intended to update initrd for all my kernels ;).

Watch out, the 2.6.24 kernel might need ide_generic to use the
controller at all.

I have ventured to update initrd for all my kernels and the result is
good! But I have one more question. There is list of my kernels:

leva:/home/anthony# awk '{if ($1=="kernel" && $NF!="single") print $2}' /boot/grub/menu.lst

468-kernel is needed for me in case I will change my cpu to 686-incompatible :) or I will transport my hdd to old computer and boot Debian from it.

AFAICT, the only currently-shipping ia32 686-incompatible chips are the Via C7 chips which go in little semi-embedded machines.

But can I boot at least one of my kernels if I simply change my motherboard to one with non-nVidia chipset (that don't use "amd74xx" module) (after updating initrd for all kernels)?

Yes. That's how I moved my hard drive from my old machine to the new one.

good scientist into a bad one; and in some cases, they can turn
a good scientist into a charlatan."
