Hello Emmanuel,

In the old VM running in VMware5 the /proc/cmdline is *ro root=/dev/sda1 
rhgb quiet console=tty0*
When I try to start using Knoppix7 ... I see the file system, but /dev 
is EMPTY
When I try to start using RHEL4 rescue, I receive the following message:
     It has not found any fixed disk. It is probably that the device 
drivers must be selected manually to proceed with the installation

Thank you, Edgardo
