The folder "server" can be ignored, unless you want to install IndustrialCraft on your own server.
To do this, first install the SDK MP ModLoader Server (or patch your minecraft_server.jar to become one).
You need the server-sided ModLoader MP, don't try the one you downloaded for your client!
Then just drop all content of the "sever" folder into your minecraft_server.jar.
If you have trouble with installing the server. Read following errors first:
Problem: If i put stuff in the crafting window, it displays the item, but i can't take it from the slot. Solution: The server you're playing one is not (properly) modified. Ask the server admin to check the installation instructions.
Problem: ClassNotFoundException Solution: You've forgot one or more files, probably a prequesite mod.
Problem: After modifying the minecraft.jar, nothing changes. I can't use new recipes and don't find any new ore. Solution: You probably forgot to install ModLoader as well. No ModLoader, no mod being loaded.
Problem: You are missing the following mods: mod_IndustrialCraft x.xx Solution: Either you or the server are using an outdated / incorrectly installed version of IndustrialCraft. Fix the install to continue.
Problem: I've loaded a savefile, but can't find any of the new ores. I can craft stuff of the mod (like the Iron Furnace), though. Solution: You can't find the new ores on chunks that were generated before installing the mod. Either start a new world or explore new parts of your world, these will contain new ore.
Problem: Minecraft crashes if i rightclick on an already placed machine. Solution: You're using an incompatible version of ModLoader. Check the descriptions above to see which version is ned for this mod.
Problem: Upon loading, Minecraft stops and gives me an error: "Slot xxx is already used". Solution: One of the other mods you've installed does have an item/block with the same ID as my mod. Use the config file of IndustrialCraft, to replace the double-used ID with any other ID that's free. Block IDs are 0-255, Item IDs are 256-32000.
Problem: The sprites aren't correctly displayed. They look messy / white / pink-square. or Problem: Upon loading, Minecraft stops and gives me an error: "couldn't load image on index 0" (or similar) Solution: Some kind of HD-mod/patch is intereferring with correct sprite display. IndustrialCraft is not and won't be compatible with anything besides 16x16 solution.
Problem: Upon loading, Minecraft stops and gives me an error: "No further terrain/sprite indices left" Solution: You over-modded your minecraft.jar, the game can't handle that many new item sprites / bock textures.
Consider removing some mods / setting up a fresh vanilla minecraft.jar .
