EMORY
(SDRAM)
The IRV-3702 SBC can support up to 1G-bytes of synchronous dynamic random access memory
(SDRAM) organized as four banks of 32Mx72 including eight parity bits. The memory is configured using four dual in-line memory module sockets, which will accept 168-pin dual in-line memory modules (DIMMs) organized as 256MB (maximum) with a maximum access time of 10ns.
DMA C
ONTROLLER

The two DMA controllers are cascaded to provide four DMA channels for transfers to 8-bit peripherals (DMA1) and three channels for transfers to 16-bit peripherals (DMA2). DMA2 Channel 0 provides the cascade interconnection for the two
DMA devices thereby maintaining IBM PC/AT compatibility. The DMA channel assignments are listed below:
DMA Channel 0: Not Used (8-bit)
DMA Channel 1: Alternate for Multi-mode Parallel Port (8-bit)
DMA Channel 2: Floppy Disk (8-bit)
DMA Channel 3: Multi-mode Parallel Port (8-bit)
DMA Channel 5: Not Used (16-bit)
DMA Channel 6: Not Used (16-bit)
DMA Channel 7: Not Used (16-bit)
The DMA request (DRQx) and acknowledge (DACKx/) lines are available on the P1 98-pin edge connector.

ORT
The IRV-3702 SBC contains an IBM PC/AT compatible keyboard controller for interfacing to a generic
IBM PC/AT compatible keyboard. The keyboard controller assembles the serial data from the keyboard into bytes and interrupts the CPU via IRQ1 after each byte is ready to be read. The IRQ1 service routine reads port 60H to get the keyboard scan code and acknowledges by sending a positive
3
pulse to port 61H to clear the interrupt for the next byte. Refer to Appendix D for the keyboard connector location and pin assignments.

The IRV-3702 SBC contains an IBM PS2 compatible mouse port for interfacing to a generic serial mouse. The mouse port controller assembles the serial data from the mouse into bytes and interrupts the CPU via IRQ1 after each byte is ready to be read. The IRQ1 service routine reads port 60H to get the scan code and acknowledges by sending a positive pulse to port 61H to clear the interrupt for the next byte. Refer to Appendix D for the mouse port connector location and pin assignments.

IMER
The IRV-3702 SBC includes a WatchDog Timer circuit. The WatchDog Timer ensures that if an application program gets "lost or bombs", the system will reset or a non-maskable interrupt will be issued to the CPU. The WatchDog Timer is enabled by reading I/O port 443H. Once enabled, the
WatchDog Timer must be triggered by reading I/O port 443H within the time out period, otherwise the WatchDog Timer will force a hardware reset or activate the IOCHCK/ line, generating a nonmaskable interrupt (NMI). The WatchDog Timer can be disabled by reading I/O port 43H. A jumper is provided to select the time out period and to enable the WatchDog Timer circuit. Refer to Appendix

The IRV-3702 includes a socket designed to accept the MCSI PROMDISK-Chip. The PROMDISK-Chip
Disk Emulator is a unique Flash Memory array which emulates a bootable read/write hard disk drive.
The PROMDISK-Chip is offered in 4M, 8M, 16M, and 32M byte capacities and comes complete with
ROM-DOS version 6.22 installed. The PROMDISK-Chip occupies an 8K block of memory space above
640K, whose starting address is selected by jumper JP11. The PROMDISK-Chip uses the Datalight
Flash/FX integrated Flash File System and boot utilities. Refer to Appendix E for the jumper location.
The Flash/FX Variable Block Flash (VBF) File System and ROM-DOS allow the PROMDISK-Chip to operate as a non-volatile Read/Write disk drive. This means that you can list directories, copy files, and read and write to the Flash memory on PROMDISK-Chip through standard DOS interrupts and commands.

ETUP
The IRV-3702 SBC uses the latest AMI Plug-n-Play BIOS that contains an internal Setup Utility for configuring the system. The BIOS includes a graphical user interface, and a new system configuration utility, as well as all the features of the standard BIOS. The system configuration settings are stored in the on-board CMOS memory which is backed up by a Lithium battery.
The Setup Utility can be invoked by first causing a cold boot (reset) or a warm boot ( Cntrl Alt Del ) and pressing the Del key when instructed. This will cause the memory diagnostics to be aborted and the Setup Utility to display the MAIN SETUP MENU. Using the
→ cursor keys, move the highlighted bar to the option you wish to modify and then press Enter to select it. When in the
MAIN SETUP MENU, the F2 key is used to select the colors used in the setup screens, and the F10 key is used to save the changes before exiting the Setup Utility. The Esc key may be used to exit the
Setup Utility without saving the changes. The PgUp and PgDn keys are used to scroll through the selections for a given setting. PgUp is also used to decrease the setting and PgDn to increase the setting. In addition, you may also enter the setup utility directly by pressing the Cntrl Alt Esc simultaneously. A jumper at JP4 is provided to force the BIOS to use its internal default SETUP values.
This is accomplished by first removing power from the IRV-3702 and momentarily interrupting the battery power to the system controller chip. To interrupt the battery power, install a shunt on pins 3 &
4 momentarily (the "Clear CMOS" position). After waiting a few seconds, remove the shunt jumper.
Note: This procedure must be performed with the power on.
After making the desired selections from the various setup menus, you can save your selections by pressing the F10 key or by selecting the appropriate selection from the MAIN SETUP MENU.
Notes:
1. The user should be aware that improper selection of certain values in the CHIPSET, POWER
MANAGEMENT, and PNP/PCI selections may cause unpredictable results. If this occurs select the
FAIL SAFE SETTINGS from the MAIN SETUP MENU and then press the F10 to save and exit.

During the POST (Power On Self Test) routines, which are performed each time the system is powered on, errors may occur.
Nonfatal errors are those which, in most cases, allow the system to continue the boot up process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal error occurs, you should consult with MCSI Customer Service for possible repairs.
These fatal errors are communicated through a series of audible beeps. The numbers on the fatal error list below correspond to the number of beeps for the corresponding error. All errors listed, with the exception of number eight, are fatal errors.
No. of Beeps Error Message
1 Refresh Failure - The memory refresh circuitry is faulty.
2 Parity Error - A parity error was detected in the first 64K block of system memory.
3 Base 64KB Memory Failure - A memory failure occurred within the first 64KB of
memory.
4 Timer Not Operational - Timer #1 has failed to function properly.
5 Processor Error - The CPU chip has generated an error.
6 8042-Gate A20 Failure - The keyboard controller (8042) contains the Gate A20
switch which allows the CPU to operate in virtual mode. This error message means
that the BlOS is not able to switch the CPU into protected mode.
7 Processor Exception lnterrupt Error - The CPU chip has generated an exception
interrupt.
8 Display Memory Read /Write Error - The video adapter is either missing or the
video memory is faulty. PLEASE NOTE: This is not a fatal error.
9 ROM Checksum Error - The ROM checksum value does not match the value
encoded in the BIOS.
10 CMOS Shutdown Register Read/Write Error - The shutdown register for the CMOS
memory has failed.
11 Cache Memory Read/Write Error - A Cache Memory failure occurred, do not enable
the Cache Memory to resume operation.
