    Hi. Change the C1 and L3 (use a cable for L3). I turned on the IIFX with floppy disk but no hard drive. The IIFX turned on correctly, showing video and asking for SO. Turn off IIFX, connect the HDD, turn on the IIFX and PLUFFFF, again explode the C1. Measuring the continuity of C1 and L3, these...
