problem copying knoppix kernel to hard drive

hey everyone,

I'm using arch linux on my hard drive and I am unable to get pci hotplugging to work.
A knoppix-std live cd that I have IS able to get things to work, so I thought I would copy the knoppix-std bzImage, System.map, and config files over to my arch-linux hardrive.

When booting up, I got the message that there was a kernel panic and that I needed to change my "root=" statement, so I'm not sure what I should do.

When I boot up from the knoppix-std livecd, the files in the /boot directory are named 2.4.21-xfs, System.map-2.4.21-xfs, config-2.4.21-xfs.old.

do the names of these files indicate that I should be using the xfs filesystem? Is that the problem? I don't understand why things are not working.

Hmm...might help if we knew a little more. My guess is that you have the ``root'' value set incorrectly. To quote the manual:

Quote:

root=<root-device>
This specifies the device that should be mounted as root. It may be specified as a global option. If the special name current is used, the root device is set to the device on which the root file system is currently mounted. If the root has been changed with -r , the respective device is used. If the variable `root' is omitted, the root device setting contained in the kernel image is used. (And that is set at compile time using the OOT_DEV variable in the kernel Makefile, and can later be changed with the rdev(8) program.)

Just a thought. Notably, however, I'm not a guru though.

the root value is correct.
My grub config file works fine as long as I choose to boot the kernel image that I made from my 2.4.31 kernel. This is a very normal type of thing that I am familiar with.

inserting a kernel image from the knoppix-std livecd into my /boot directory, however, and configuring my grub config file to boot THAT kernel image INSTEAD is different. That is not a normal type of thing to do (I don't believe). I am not familiar with it.

In theory it should work, shouldn't it? Is it necessary for me to be using xfs?
does anyone have any experiece with this?

I'd like to say, straight off the bat, that I am not really that good w/ kernel configuration, but here are my two cents...

The main part of the kernel is merely the main part. What about those other modules. (/lib/modules) Maybe you missed something from there.

But like I said, I honestly don't know too much.
