 +== Modes of Powering the DSM (temporary!) ==
 +
 +The DSM can be brought up in two different ways as of now.
 +
 += Full DSM (be careful!) =
 +We can power on the **full DSM**, the entails cooling the whole analog logic inside the DSM's main module (with water!) and allows almost full operation (except for the column, for now).
 +Before proceeding, make sure the water chiller is connected to the DSM (water hoses), is turned on and does not leak.
 +Insert the way-too-premium custom power cable (gray cable, black plug) into the pRCD-equipped outlet. Make sure the gray IEC-cable (marked P1) is connected to the BIVAS.
 +
 +**WARNING: ** Doing this enables live voltage inside the DSM, regardless of the state of the main/secondary power switch on the DSM. Nice design Zeiss, thanks!
 +
 +After this cable is connected the upper 3 LEDs on the Powersupply will turn on (again, regardless of the state of the power switch). Turn the power switch on (bringing up some more LEDs) and then turn the power key to enable power to the distribution panel, which will in turn bring up the BIVAS.
 +
 +In this mode, all features should be available to you (except the column) and the DSM will boot up normally (see bringup for details).
 +
 += BIVAS only =
 +
 +Rather than bringing up the full DSM, we can also just bring up the BIVAS along with the keyboard, floppy drive and screen. 
 +
 +Connect any IEC power cord to the BIVAS's P1 connector. Connect to the pRCD equipped outlet. Make sure the DSM's way-too-premium custom power cable (gray cable, black plug) is **not connected**.
 +The BIVAS will turn immediately when power is applied, this is expected (it's not //really// meant to run standalone).
 +
 +This mode will not currently boot into the DSM application, but it allows full access to the DOS prompt, however the whole main unit of the DSM can stay powered off, so no water-cooling is necessary.
 +
 +==== Vacuum-System ====
 +
 +The vacuum system looks like follows:

 +The original roughing pump (RP) is an Edwards E2M8 rotary pump, our DSM is equipped with a Pfeiffer TPH 240 IS turbomolecular pump.
