A solid HDD light typically uses a floppy cable placed upside-down, ensuring proper grounding. Although you seem to have an Alps Electric Co. FDD and the cable setup matches what the manuals suggest, the ECS manual is too low resolution to interpret clearly. Checking for pin1 and pin34 markings on both ends is recommended. A jumper on JP1 sets the board for SDR mode, not DDR. Applying 3 volts to DDR might cause damage (it's a 20% overvoltage), though it could also prevent functionality. You have a supported 533MHz FSB processor in the 2.4B, but you've jumpered it to run at 400MHz—this is quad pumped, so the board should be labeled 133 or 100MHz. Operating at 1.8GHz is possible, but we can't confirm if JBAT1 was changed for CMOS Clr. P4X333 was intended for AGP 8x, but it appears faulty, now only supporting 4x with 1.5V signals. Most GeForce 2 MX 400 models are designed to work at both 3.3V and 1.5V, so this should be fine.
The nit bit adjustment essentially mimics a flywheel effect in a motor, assisting in maintaining stable DC voltage.
