B0 Dec. 2000 Chapter 1 Introduction Welcome to the PEAK 602VL the most powerful Intel 815E based single board computer. The PEAK 602VL Series featured the high performance Intel Celeron / Pentium III CPU and 815E chipset, is a power packed Half-sized Single Board Computer. The PEAK 602VL Series provides 100/133 MHz FSB ® support for Pentium III processors up to 1GHz. The Intel 815E chipset is equipped with internal graphics, LAN, and support for 2 USB ports, Ultra DMA66/100 IDE interface. The major features of PEAK 602VL Series are as follows: 1. Intel Pentium III FC-PGA support, 100/ 133 MHz FSB, up to 1+ GHz CPU clock. 2. PC133 SDRAM support up to 256 MB max. 3. On chip 2X AGP VGA with Intel Dynamic Video Memory Technology 4. On chip Ethernet 10/ 100 Mbps, all Intel solutions. Upgradeable to Dual LAN. 5. On Chip enhanced IDE x 1, support Ultra DMA/66/100 6. On Chip 1 USB controllers double the bandwidth to 24Mbps across 2 ports 7. Hardware Monitor for system Voltage, Temperature and FAN speed. 8. Reserved Power header beside IDE connector to support DOM ( DiskOnModule ) 9. NEXCOM proprietary PCI connector for various upgrade modules like: � EBK SCSI 2: Support Ultra 2 SCSI � EBK SCSI 160D: Support dual Channel Ultra 160 � EBK 160SL : Support one Channel Ultra 160 SCSI and one Intel 82559 LAN. Not only for the standard SBC application, the PEAK 602VL Series include the on board Power Input connector, which can also be run as independent system without the backplane installed. Considering the placement of PCI extension controller on the SBC under the space limit, we design the on board NEXCOM proprietary PCI Interface that allows the upgrade module to be mounted. The optional EBK SCSI 2 / EBK SCSI 160D / EBK 160SL module designed with Adaptec AIC-7890 Ultra 2 SCSI / AIC-7899 Dual Channel SCSI 160 / AIC-7892 SCSI 160 + Intel 82559 LAN controller, enhances PEAK 602VL Series a featured-rich single board computer. The PEAK 602VL Series series is suitable for the standard Half-Size SBC application with ISAMAX up to 20 ISA devices and embedded system and special applications required the small size Form Factor and supports for the Linux, Windows 2000, Windows NT Operation system.

B0 Dec. 2000 Chapter 3 Capability Expanding This chapter explains how you can expand capability of your CPU board in such aspects as system memory and CPU. 3-1 System Memory Peak602VL support 2 slots for 168-pin 3.3V Non-registered DIMM modules, providing support for up to 512MB of main memory using DIMM modules from 8MB to 256MB. The following is the example to install the system SDRAM memory module combination. Note: 1. It is highly recommended to use the PC-100 or PC-133 Specification DIMM module. 2. Due to limitation of Intel 815E chipset, the board can’t support the ECC memory module. To insert the DIMMs, the modules must be oriented in the correct way. Notice the notches of the DIMM. Align these notches as shown in the diagram below. Gently push the DIMM until the retainers on both sides of the socket lock the module in place. To remove a DIMM, push the retainers outwards to release the module then pull the module out of the socket. 3-1 Capability Expand Peak 602VL User's Guide Rev. B0 Dec. 2000 3-2 Change CPU To change the CPU, pull the handling bar of the socket upward to the other end to loosen the socket's openings. Carefully lift the existing CPU up to remove it from the socket. Removing CPU Place the new CPU on the middle of the socket, orienting its beveled corner to line up with the socket's beveled corner. Make sure the pins of the CPU fit evenly to the socket openings. Replace the handling bar to fasten the CPU to the socket. Be sure to re-arrange the jumper setting for the correct external clock.

B0 Dec. 2000 Advanced Chipset Features Setup Menu Since the features in this section are related to the chipset in the CPU board and all are optimized, you are not recommended to change the default settings in the setup table, unless you know very detailed of the chipset features. This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as DRAM and the external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system. The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system had mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips. SDRAM CAS Latency Time When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. The Choice: 2, 3 SDRAM Cycle Time Tras/Trc Select the number of SCLKs for an access cycle. 4-13 BIOS Setup Peak 602VL User's Guide Rev. B0 Dec. 2000 The Choice: 5/7, 7/9. SDRAM RAS-to-CAS Delay This field let’s you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or refreshed. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. The Choice: 2, 3. SDRAM RAS Precharge Time If an insufficient number of cycles is allowed for the RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the system. The Choice: 2, 3. System BIOS Cacheable Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. The choice: Enabled, Disabled. Video BIOS Cacheable Select Enabled allows caching of the video BIOS, resulting in better system performance. However, if any program writes to this memory area, a system error may result. The Choice: Enabled, Disabled. Memory Hole At 15M-16M You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, it cannot be cached. The user information of peripherals that need to use this area of system memory usually discusses their memory requirements. The Choice: Enabled, Disabled. CPU Latency Timer When enabled this item, the CPU cycle will only be deferred after it has been held in a “Snoop Stall” for 31 clocks and another ADS# has arrived.

The WDT function is to monitor the computer system whether work normally, otherwise, it will have some measures to fix up the system. It contains a receivable SQW signal from RTC, and could set time and can clear the counter function. When time is up, WDT can send Reset or NMI signal. Operator has to write a value into WDT Configuration Register (Write the control value to the Configuration Port), and clear WDT counter (read the Configuration Port).
