I read the man initrd and it said to make a new file for use you do this:

CONFIGURATION

The /dev/initrd is a read-only block device assigned major number 1 and minor number 250. Typically /dev/initrd is owned by root.disk with mode 0400 (read access by root only). If the Linux system does not have /dev/initrd already created, it can be created with the following

      commands:

              mknod -m 400 /dev/initrd b 1 250
              chown root:disk /dev/initrd

Also, support for both "RAM disk" and "Initial RAM disk" (e.g. CON- FIG_BLK_DEV_RAM=y and CONFIG_BLK_DEV_INITRD=y ) support must be com- piled directly into the Linux kernel to use /dev/initrd. When using

      /dev/initrd, the RAM disk driver cannot be loaded as a module.

Well I looked for /dev/initrd in this computer and there is none! So I think the man page is wrong! Well this is it about for me. All the Google data is for Red Hat 6.

You don't need /dev/initrd - you need /boot/initrd-your-kernel-version.img as mentioned in grub. man mkinitrd will show the command to build a new one and the only special trick is that you need to put the necessary but missing 'alias' entries in /etc/modprobe.conf first so it will include your driver modules in the new image.

Well Les, I have no idea what Internet thing I have, no idea what the sound card is called. So I deleted the ones from this computer. But when mkintrd ran it said can't make it because it exists. So I deleted the 2 in /boot. Then ran it and said "no modules available for this kernel".

So guess I'm dead. we need a real F7 HowTo for this. It is now a catch 22 thing.

I am probably flogging a dead horse here but the whole point of anaconda
is to detect your hardware and install an OS that is compatible with
your hardware - which is of course lost when you run the installer on
one system and then copy the installation over to another...this is
often a problem on Windows too.

As for an F7 HowTo - I'm quite sure that information regarding hardware
detection, modprobe.conf and initrd is out there and very little
difference would be found between FC6 and F7 but those without the
experience/skill sets to manage it would find it endlessly confusing.
Case in point...I found a walk through for compiling the old megaraid
modules on RHEL 4 on the Internet which worked fine on RHEL 4.0 but had
to be adjusted when Red Hat shipped RHEL 4.1 or a number of adjustments
had to be made for CentOS because their CentOS-4 installation CD used an
i586 boot kernel instead of an i686 boot kernel. Even with walk the walk
through and my noted changes for CentOS were so difficult that I only
noticed 1 other person on the CentOS mail list that was capable of
getting it accomplished.

Short of above...re-install directly on the hardware you are going to be
using and problems go away.

All your above is about old Linux so you know NOTHING about F7.
