1.6Before you proceed
Take note of the following precautions before you install motherboard components or change any motherboard settings.
1.Unplug the power cord from the wall socket before touching any component.
2.Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.
3.Hold components by the edges to avoid touching the ICs on them.
4.Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.
5.Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.
1.7Central Processing Unit (CPU)
The motherboard provides a Socket A (462) for CPU installation. AMD processors offer gigahertz speeds to support all the latest computing platforms and applications. The A7S266-VM supports AthlonTM XP/AthlonTM and DuronTM processors.

1.8System memory
The motherboard has two Double Data Rate (DDR) DIMM sockets and two Single Data Rate (SDR) DIMM sockets that supports up to 2GB nonECC PC2100/1600 DDR and PC133/100 SDRAM DIMMs.
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a DDR DIMM is single notched while an SDR DIMM is double notched.

1.A DDR or SDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.
2.DDR and SDRAM memory slots cannot be used simultaneously.

1.9Expansion slots
The A7S266-VM motherboard has four (4) expansion slots. The following sub-sections describe the slots and the expansion cards that they support.
1.9.1Configuring an expansion card
After physically installing the expansion card, configure the card by adjusting the software settings.
1.Turn on the system and change the necessary BIOS settings, if any.
2.Assign an IRQ to the card. Refer to the tables below.
3.Install the software drivers for the expansion card.

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between two PCI groups.
