You have presumably loaded the ramdisk module first, or have kerneld
running?

Have you told the ramdisk driver to allow 32M ramdisks? Certainly in
the 2.0.35 kernel in use here, it defaults to a maximum of 4M per
ramdisk.

In my case, I've done the following for a 4M ramdisk:
dd if=/dev/zero of=/etc/rd bs=1k count=4096
mke2fs /etc/rd
gzip -9 /etc/rd
Then as part of my startup script, I have the following command before
the "mount -a" line:
gunzip < /etc/rd.gz > /dev/ram
This works for me every time...
Best wishes from Riley.
