I can at least speak to one of your issues. When you hit F6 for raid, it is later on that you will then be asked to load the drivers from the disk, not right then. Eventually a screen should appear that asks you to load the drivers, which you do from a floppy. But, you have to have the raid array already maid, which is usually done by enabling it in your bios, then hitting F(something) when prompted during boot up. Your one memory stick seems obviously bad, but I'm sure other more experienced people on here will give you more insight. If you get an error code though, you can usually look that up on-line. It also seems as though your vid card is faulty as well. Good Luck.
