Well, I've just tried env-handler, installed it on C and disabled the commands it says and the chip ram is the same (in fact, I loose some kbs).
" They give you lots of benefits, including very large harddisk support, fixed ram disk space, faster and better behaved scsi.device, etc."
In fact, I'm upgrading with a Transcend 32Gb CF and an internal Cd that I had working flawlessly using Smart File System and a cracked Idefix under BB2. I don't wanna be the pessimist here, it must be the benefits are in things I've never had problems before, like that ram disk space... But where I can start to have problems is in any Game or program needing enough chip ram.
