3 Installation Preview Before you install the SQ575 mainboard into the system chassis you may find it convenient to first configure the mainboard hardware. This section describes how to configure the jumper settings, install memory modules, and how to attach the various system components. Before using your computer you must review the following 7 steps: 1. Jumper settings 2. Installation of DRAM modules (SIMM or DIMM) 3. Installation of the CPU 4. Installation of expansion cards 5.
3.1.2 Setting 3-pin jumpers Jumper Pins 1 & 2 are closed with a jumper cap Jumper Pins 2 & 3 are closed with a jumper cap 3.1.3 Setting 2-pin jumpers This jumper is closed with the jumper cap placed over 2 pins This jumper is open with the jumper cap removed from the 2 pins WARNING: Some pins are used for connectors or power sources. These are clearly marked separately from the jumpers listed in “Mainboard Layout”.
Processor Voltage JP6 JP7 JP13 JP14 JP15 JP16 VCORE=3.38V VI/O=3.38V VCORE=3.2V VI/O=3.3V VCORE=2.9V VI/O=3.3V VCORE=2.8V VI/O=3.3V 3.1.6 Processor/System Speed setting (JP4, JP5, JP8, JP9 & JP10) The system speed depends upon the frequency of the CLOCK GENERATOR which is determined by jumpers. These jumpers tell the system what speed to run at. Currently, this mainboard speed range is from 90MHz to 233MHz.

1) You must use one pair of sockets at a time in sequence ( i.e. SIMM1 and SIMM2, or all four sockets at once). 2) Each pair of modules must be the same size and speed and may be single sided or double-side. Module sizes: Single-side SIMMs: 4MB, 8MB, 16MB; Double-side SIMMs: 8MB, 32MB, 64MB 3.2.
3.2.3 Installation Procedure for SIMM Insert SIMM into the SIMM sockets at a degree angle. 1) PIN1 of the SIMM module must match with the PIN1 of the SIMM socket. 2) The module will only insert into the socket one way. An orientation cut-out will prevent you from inserting it the wrong way. 3) Insert the SIMM into the SIMM socket at a 45 degree angle. If pin 1 of the SIMM does not line up with pin 1 of the socket, the SIMM will not insert into the socket.
Type 168-pin 3.3V unbuffered EDO DRAM DIMM with serial presence detect 168-pin 3.3V unbuffered EDO DRAM DIMM with serial presence detect 168-pin 3.3V unbuffered EDO DRAM DIMM with serial presence detect 168-pin 3.3V unbuffered SDRAM DIMM with serial presence detect 168-pin 3.3V unbuffered SDRAM DIMM with serial presence detect 168-pin 3.3V unbuffered SDRAM DIMM with serial presence detect 168-pin 3.3V unbuffered SDRAM DIMM with serial presence detect 168-pin 3.
3) Insert the DIMM into the DIMM socket at a 90 degree angle. If pin 1 of the DIMM does not line up with pin 1 of the socket, the DIMM will not insert into the socket. After inserting the DIMM completely into the socket, push up on the socket latches securing the DIMM into place. 4) To release the memory modules, push both latches down and carefully rock the module forward Important: Do not use DIMM which use an extra TTL to convert the memory module from asymmetric to symmetric. 3.
3.4 Installation of Expansion Slots: 3.4.1 ISA & PCI Slots There are two types of ISA expansion cards, design-Legacy and PnP (Plug & Play). For Legacy cards you must set the cards’ jumpers manually. For Plug & Play cards, your system will adjust the IRQs automatically. You can verify the IRQ allocation either by using Microsoft’s Diagnostic (MSD.EXE) utility which is in the Windows directory or through the Windows 95 resources menu. 32-bit PCI Slot 16-bit ISA Slot 3.4.

The case must reserve space for the IR module if you want to use the IrDA function.
3.5.14 Parallel Port Connector (26-pin Block) (J7) The motherboard includes a bi-directional parallel port (EPP/ECP compatible). The parallel port is capable of being disabled or remapped to either the secondary LPT address or the primary LPT address through BIOS if other parallel ports are installed. The parallel port contains 12mA source output drivers on the drive interface and incorporates Chip Protect circuitry for protection against damage due to printer’s power being on.
4 BIOS Setup The SQ575 mainboard uses an Award BIOS, which is stored in a Flash EEPROM and which can be upgraded using a floppy disk-based program. The BIOS has a built-in Setup program that allows users to modify the basic system configuration setting. The settings are then stored in a dedicated battery-backed memory, called CMOS RAM, that retains the information when the power is turned off. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems.

Main Setup Menu When you enter the Award BIOS CMOS Setup Utility, a Main Menu (Figure 1) appears on the screen. The Main Menu allows you to select from several Setup functions and two exit choices. Use the arrow keys to select among the items and press Enter to accept and enter the sub-menu. A brief description of each highlighted selection appears at the bottom of the screen. ROM PCI/ISA BIOS (2A59IB3G) CMOS SETUP UTILITY AWARD SOFTWARE, INC.
Standard CMOS Setup Menu In the Standard CMOS Menu (Figure2) you can set the system clock and calendar, record disk drive parameters and the video subsystem type, and select the type of errors that stop the BIOS POST. ROM PCI/ISA BIOS (2A59IB3G) STANDARD CMOS SETUP AWARD SOFTWARE, INC.
1) Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45. 2) Select USER and enter values into each drive parameter field. 3) Use the IDE HDD AUTO DECTECTION function in Setup. Here is a brief explanation of drive specifications: _ Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors.
4.3.5 Video Select the type of primary video subsystem in your computer. The BIOS usually detects the correct video type automatically. The BIOS supports a secondary video subsystem, but you do not select it in Setup. EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA, SEGA, SVGA or PGA monitor adapters. CGA 40 Color Graphics Adapter, power up in 40 column mode. CGA 80 Color Graphics Adapter, power up in 80 column mode.
Other Memory Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stayresident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory. Total Memory System total memory is the sum of base memory, extended memory, and other memory. 4.
BIOS Features Setup Menu This screen (Figure 3) contains industry-standard options additional to the core PC AT BIOS. This section describes all fields offered by Award Software in this screen. Some fields may vary from those in your Setup program. Your system board designer may omit or modify some fields. ROM PCI/ISA BIOS (2A59IB3G) BIOS FEATURES SETUP AWARD SOFTWARE, INC.
4.4.4 Boot Sequence The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However, the BIOS now offers 10 different boot sequence options of three drives each. In addition to the traditional drives A and C, options include IDE hard drives D, E, and F; plus a SCSI hard drive and a CD-ROM drive. 4.4.
4.4.12 Assign IRQ for VGA Assign the IRQ# for VGA card. 4.4.13 OS select for DRAM > 64MB Select OS2 only if you are running OS/2 operating system with greater than 64 MB of RAM on your system. 4.4.14 Shadow Software that resides in a read-only memory (ROM) chip on a device is called firmware. The Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor.
