root=/dev/ram0

You might want to try setting ramdisk_size too.  It's been a while since I
played with this stuff and the argument may be called something else.

What other informatin would be useful?  This has got me stumped.  The
ramdisk support in the kernel seems to be working OK.  I booted the
system up with an nfs mounted root partition and did the following:

        #dd if=/dev/zero of=/dev/ram0 bs=1k count=4096
        #dd if=/fs of=/dev/ram0    (fs is my filesystem image)

This went off without a hitch so I tried mounting /dev/ram0:

        #mount /dev/ram0 /mnt

also fine and when I look in /mnt the filesystem looks OK too.

Thanks,
Andy
