NVROM virus on iBook G4 ??

Hello cruel cruel World .

I have tried with 4 different versions of Linux or UNIX for PowerPC .

Before that , I tried to dual-boot with a de-facto Mac OS 10.5.(?) Leopard for PowerPC . I picked a BSD UNIX OS .

Initially it worked then it froze and the hard drive crashed (FAT broke.) Perhaps a rouge versioning .

Then I used a LIVE CD of UNIX PowerPC which on the Home Site said it has a GUI with the text prompt command window . It was false there was only a text mode prompt . During installation without a-priori mandate asked for my PASSWORD to MY ROUTER !

After that I have tried using LIVE CD and it does not install . And the command prompt at the BIOS screen did alll types of weird things due to what I suspicious of as NVROM virus .

I definitely wants the original Leopard OS not an imitator(?)

Bye cruel world .
