The Foxconn 661MX Plus is a MicroATX motherboard capable of supporting Intel Pentium 4 and Intel Celeron brand CPUs. An older motherboard, the 661MX Plus, supports PATA hard drives instead of newer SATA hard drives. The MicroATX form factor limits the number of expansion ports on the motherboard, but it allows the motherboard to be installed in both MicroATX and Standard ATX computer cases.
CPU, Memory, and Hard Drive Support
The 661MX Plus supports Intel Socket 478 chips, including the Celeron, Celeron D and certain Pentium 4 processors. The motherboard's 500/433Mhz frontside bus (FSB) will not support Pentium 4 processors with an 800Mhz FSB. The 661MX Plus has two slots for single channel DDR memory, and it can support up to 2GB of DDR266/333/400MHz memory. The 661MX Plus contains two Parallel ATA (PATA) slots capable of supporting PATA hard drives. The motherboard does not have native support for Serial ATA (SATA) drives.
Integrated Features
The 661MX Plus utilizes an integrated SIS Mirage graphics chip to supply VGA output. A Realtek ALC655 audio interface manages the line-in, line-out and microphone ports. Onboard Ethernet support is available through a 10/100Mbps LAN interface. The motherboard has 4 USB 2.0 ports for peripherals, in addition to two PS/2 ports, one parallel port and one serial port. The motherboard does not have native IEEE1394 (Firewire) support.

ATX Specifications and BIOS Features
The 661MX Plus uses the MicroATX form factor, and it measures 9.6 inches by 8.0 inches. It can be installed in all cases that meet MicroATX and Standard ATX specifications. The motherboard receives power through a 20-pin ATX Power Connector. The BIOS can be updated through Windows with the SuperUpdate utility application and overclocked with the SuperStep application.
