I tried to install 1.6.2 on my eMac, but I'm unable to run disklabel 
and newfs on the 1.6.2 install disk. I follow the detailed installation 
instructions, but when i try to write the disklabel to disk I get:

partition> W
Label disk [n]? y
disklabel: ioctl DIOCWDINFO: Label magic number or checksum is wrong!
(disklabel or kernel is out of date?)
Label not written

Same story with newfs:

newfs: ioctl (WDINFO) Invalid argument
newfs: /dev/wd0a: can't rewrite disk label

What's all this about? Am I doing something wrong?
