[clue-tech] Driver Disk?

I have consolidated several sources (some RedHat, some SuSE, etc.) into 
the following procedure.  However, I am unable to get the CentOS 4 
installer to mount the newly crafted Driver Disk when prompted.  I've 
tried three different floppy disks to no avail, so I don't believe it's 
a matter of bad disks.  In fact, this same machine CAN mount and read 
the disk when I let the older CentOS 3 OS boot up.

I don't know why the CentOS 4 installer won't mount these disks and I 
hope any of you might be able to offer some tips.  This is the first 
time I've ever attempted to build a Driver Disk, so I'm clearly missing 
something.

Some ideas (though I'm frustrated and can't think clearly about what to 
do with them):
1. The machine I'm building this Driver Disk on uses SELinux.  Can this 
be interfering (the context tags in the file-system that is created on 
the floppy), somehow?
2. I create a file called centos-4, following an example used in a very 
old redhat-6 Driver Disk example.  Is it possible that CentOS 4 doesn't 
recognize the file; that it should be named redhat-something?
3. Is the installer expecting to mount an ms-dos (or other non-ext3) 
file system?
4. In the various Driver Disk images that I'm working with (for other 
OSes and other, unrelated devices), I noticed that the various files 
show no user/group ownership.  As I'm dealing with .IMG files, I have no 
idea what the file-system they were based on is (safe to assume it's 
ms-dos?).  Is this important to the Linux installer?

Thanks for any help!
