Questions about changing PS3

[Sporadica]

I know that firmware update 3.21 removed the ability to put OtherOS on, but is there a way that I could install Ubuntu onto the PS3 by removing the firmware and how would I remove firmware?

Also PS3 uses FAT32, is there a way that I can put an NTFS drive into the PS3 and when I boot it up will it just install the PS3OS automatically? or am I stuck with FAT32? because I prefer NTFS for various reasons.

The only operating system you have is the PS3 System Software provided by Sony. Unless you want to spend time becoming a profession PS3 Software exploiter, and then getting sued by Sony, then don't bother ;
