I tried if PC-BSD supports my hardware (Toshiba Satellite Pro A200).
1. try: using USB-Live 32 bit. On boot it stucks with a black screen showing only "|".
2. try: using Live DVD 32 bit. It prints:
CD Loader 1.2
Building the boot loader arguments
Looking up /BOOT/LOADER... Found
Relocating the loader and the BTX
Starting the BTX loader
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
BIOS CD is cd0
BIOS drive A: is disk0
BIOS drive C: is disk1
Thats's all. Then it hangs.
Thats' sad. Looks like I have to stay with Linux.
