Motherboard Description SY-7VCA 1-7 MICROPROCESSOR The motherboard supports a single Socket 370 processor. The processor’s VID pins automatically program the voltage regulator on the motherboard to the required processor voltage. In addition, the front side bus speed (100 MHz and 133 MHz) is automatically selected. The motherboard supports all current Socket 370 processor speeds, voltages, and bus frequencies. 1-7.1 Microprocessor Packaging The CPU is packaged in a 370 pin PGA package.
Motherboard Description SY-7VCA 1-8 MEMORY 1-8.1 Main Memory The motherboard has three DIMM sockets. SDRAM can be installed in one, two, or three sockets. Using the serial presence detect (SPD) data structure, programmed into an E²PROM on the DIMM, the BIOS can determine the SDRAM’s size and speed. Minimum DIMM memory size is 8 MB; maximum DIMM memory size is 256/512 MB. Memory size and speed can vary between sockets.
Motherboard Description SY-7VCA Dual copies of MA signals for improved drive Optional bank-by-bank ECC (single-bit error correction and multibit error detection) or EC(error checking only) for DRAM integrity Two-bank interleaving for 16Mbit SDRAM support Two-bank and four bank interleaving for 64Mbit SDRAM support Independent SDRAM control for each bank Seamless DRAM command scheduling for maximum DRAM bus utilization (e.g.
Motherboard Description SY-7VCA 1-9 CHIPSET Ø VT82C694X The VIA 694X is a high performance, cost-effective and energy efficient chip set for the implementation of AGP/PCI/ISA desktop personal computer systems from 66MHz, 100MHz and 133MHz based on 64-bit Socket 370 super-scalar processors. The Via 694X chip set consists of the VT82C694A system controller (510 pin BGA) and the VT82C686A PCI to ISA bridge (324 pin BGA).
Motherboard Description SY-7VCA operating environments. Both Window 95 VxD and Windows 98 /NT5.0 mini port drivers are supported for interoperability with major AGP-based 3D and DVD- capable multimedia accelerators. The VT82C694X supports two 32-bit 3.3/5V system buses (one AGP and one PCI) that are synchronous/ pseudo-synchronous to the CPU bus. The chip also contains a built-in bus-to-bus bridge to allow simultaneous concurrent operations on each bus.
Motherboard Description SY-7VCA Dynamic CKE control for powering down of the SDRAM. A separate suspend-well plane is implemented for the SDRAM control signals for Suspend-to-DRAM operation. Coupled with the VT82C686A south bridge chip, a complete power conscious PC motherboard can be implemented with no external TTLs. The Via 694X chipset is ideal for high performance, high quality, high energy efficient and high integration desktop and notebook AGP / PCI / ISA computer systems.
Motherboard Description SY-7VCA environment. 3) Keyboard controller with PS2 mouse support. 4) Real Time Clock with 256 byte extended CMOS. In addition to the standard ISA RTC functionality, the integrated RTC also includes the date alarm, century field, and other enhancements for compatibility with the ACPI standard. 5) Hardware monitoring subsystem for managing system/ motherboard voltage levels, temperatures, and fan speeds 6) Full System Management Bus (SMBus) interface.
Motherboard Description SY-7VCA controller supports type F DMA in addition to standard ISA DMA modes. Compliant with the PCI2.2 specification, the VT83C686A supports delayed transactions and remote power management so that slower ISA peripherals do not block the traffic of the PCI bus. Special circuitry is built in to allow concurrent operation without causing dead lock even in a PCIto PCI bridge environment.
Motherboard Description SY-7VCA Perpendicular recording driver support Two FDDs with drive swap support Plug and play with 48 base IO address, 12 IRQ and 4 DMA options The Setup program provides configuration option for the I/O controller. 1-10.1 Serial Ports The motherboard has two 9-pin D-Sub serial port connectors located on the back panel.

Motherboard Description SY-7VCA 1-10.4 PS/2 Keyboard and Mouse Interface PS/2 keyboard and mouse connectors are located on the back panel of the motherboard. The +5 V lines to keyboard and mouse connectors are protected with a fuse that prevents motherboard components from being damaged when an over-current condition occurs. Note The mouse and keyboard can be plugged into either PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is connected or disconnected.
Motherboard Description SY-7VCA subsystem include: Ø An integrated ambient temperature sensor Ø Fan speed sensors, which monitor the fan 1 and fan 2 connector. Ø Power supply voltage monitoring to detect levels above or below acceptable values When suggested ratings for temperature, fan speed, or voltage are exceeded, an interrupt is activated. The hardware monitor component connects to the SMBus.

Hardware Installation SY-7VCA 2-3.7 Troubleshooting at First Start Video (no display) related issues I built a new computer system using a Soyo board and nothing happens when turning it on, no video and no beeps from the PC speaker. What is happening and how can it be fixed? No screen and no beeps mean that your CPU and motherboard do not work at all. It could be that the CPU is not seated correctly or that a component on the M/B is grounded (shorted) with the case.
Hardware Installation SY-7VCA My PCI VGA card works fine with my system, but when I put in a new AGP card, it does not give me any video. Is my AGP slot bad? This is a common problem with AGP video cards. The reason is that your AGP card did not get seated into the AGP slot fully and firmly. Please push your AGP card down into the socket real hard, it should snap twice. You may have to unscrew the AGP card to allow the card to go further down. Do take care not to damage the card by using too much force.
Hardware Installation SY-7VCA What you need to do is to disable 'COM2' (or UART2 or serial port 2) in the bios under integrated peripheral setup. I have installed my modem drivers several times and I still cannot get my modem to work. Why? If you are sure that the modem driver has been installed correctly, then you need to install the south bridge driver from the SOYO CD, this is because Windows does not properly recognize relatively new chipsets. Audio Issues I do not get any sound from my sound card.
Hardware Installation SY-7VCA This is because the recorder and microphone in the Windows are not enabled. Please go to sound properties and enable them. Lock up (freeze) When I boot up my system, everything works fine. It sees my CPU and memory, detects my hard drive, floppy drive and CD-ROM but locks up at "Verify DMI pool data... ", and it won’t go any further. What should I do? Please clear the CMOS via JP5 then choose 'load setup default' in the bios and save the bios and exit.
