NF4-A9A / NF4 Ultra-A9A
Step 3: Look for the white triangle on socket, and the gold triangle on CPU should
point forwards this white triangle. The CPU will fit only in the correct
orientation.
Step 4: Hold the CPU down firmly, and then close the lever toward direct B to
complete the installation.

Hard Disk Connectors: IDE1/IDE2
The motherboard has two 32-bit Enhanced PCI IDE Controller that provides
PIO Mode 0~4, Bus Master, and Ultra DMA 33/66/100/133 functionality. It
has two HDD connectors IDE1 (primary) and IDE2 (secondary). The IDE
connectors can connect a master and a slave drive, so you can connect up
to four hard disk drives. The first hard drive should always be connected to
IDE1.
This motherboard is equipped with 4 standard PCI slots. PCI stands
for Peripheral Component Inter c onn ec t, and it is a bus standard for
expansion cards. This PCI slot is designated as 32 bits.
