I have a problem whit Mac os x 10.4 install.

Before finishing the installation it throws a message that he says that I provoke a problem during the installation. I did reset to the NVRAM, alone after-taste the memory RAM of factory, made it run in sure way and throw a mistake like this: RELEASE_PPC, i remove the RAM that is not of factory and now it throws a mistake of installation that says something as:

BootFatalError-cpio read error: bad file format

Install failed: algunos archivos de essentials pueden no estar bien escritos

thank you for the help. Ronny.
