NOTE: Voltage Regulator Output Selection (VID) is not needed for the Pentium II
SEC slot because the Pentium II processor sends a VID signal directly to the CPU
card’s power controller.
IMPORTANT: Before proceeding to the next step, set the other jumpers on your
baseboard. Refer to your baseboard’s manual for the jumper settings.
2. System Memory (DRAM/SDRAM & SRAM)
Refer to your baseboard’s documentation for procedures in installing memory modules.
3. External Connectors
Refer to your baseboard’s documentation for instructions on connecting the ribbon
cables, cabinet wires, and power supply.
