Happy new year! Here is my situation, I need some input. I need to install some software (Chinese character input, ...) that are not compatible with win2k, so I'm thinking to add a "dual-boot" switch. I'm having an idea for my perfect dual-boot system. What I will need is a "Harddisk switch", which I can choose which harddisk got power. So that I can add another harddisk to my win2k machine, when I need win98, I can shut down win2k, "switch" harddisk to win98 HDD -> boot into win98 ... I don't want Boot manager software solution for personal reason. I also can't afford to mess up my win2k, so I don't want to "trick" win2k boot record around, just in case if something goes wrong... I know I need to make the switch myself, but I'm not sure which way/design is the best, and how to attach the switch to case (it's not important, but I'd like it looks good rather than bad) - I'm running out of both 3 & 5 inch bays. Here is how I want the "switch" to work: HDD1 \ -- for win2K --\ HDD2 / \ >-------HDD Power Switch HDD3 --- for win98 ----/ * when win2k is running, HDD3 has no power, when win98 runs, HDD1 & HDD2 don't get power. Could anyone give me a good design? Thanks very much!
