I just got a PMac 6500 and installed a 20 GB ide drive in it.  I 
managed to boot from the floppy dirve to install off of a cd (the cd 
won't boot) after installing NetBSD I went back to the Open Firmware 
prompt and found that Open Firmware can't see my hard disk.  Other 
posts that I've seen about booting the 6500 say to use a boot command 
like:
	0 > boot ata/ata-disk@0:0
If I use ls to show the device tree I see the ata bus 
(/bandit/ohare/ata) but it has no children.
boot ata produces DEFAULT CATCH! The same error appears if you enter a 
nonsenceical boot command like boot kbd.
If I try
boot ata/ata-disk
OF says it can't find the device.

After booting off an OS 8 cd I found that Apple's drive setup can't see 
the drive either.

Any ideas?
