cjl, antiacid, thanks for the advises.
I have another question. I'm trying to install vista on the Cheetah, but it just freeze up after i clicks Install Now. I also tries XP Pro. It was fine when format and copy files, but then when it said restart, my computer just keep restart from CD, not from the HD to continue install XP. Have any ideas? This is the first time i use SCSI HDD, so i have no idea how it works.
