Re: RH7.2 on Hercules

Was following these instructions:
http://people.redhat.com/laroche/

Install seemed to be going well, until I hit this error:
---------No Drives Found-----------
An error has occured - no valid devices
were found on which to create new
filesystems.  Please check your hardware
for the cause of this problem.
------------|OK|--------------------

What could I be missing or what relevant information should I pass
along?  I notice that there's no /dev/dasd* devices on the host system,
if there should be, or at what point these are supposed to be created. 
I'm not clear what /dev/ram0 defines:

[root@redhat80 hercules]# more hercules.prm
