Strapping field SF4 provides power-on default options for video. These straps will be set to the default value at the factory based on the flat panel configuration ordered.

Note:Maintaining an up to date chart for video strapping in this manual is not possible due to

the constant addition of new flat panel displays supported by the SBC product line. The straps in SF4 are pre-configured for the flat panel in your system. If you are experiencing problems with your flat panel, or if you are implementing a panel and require additional information, contact your Computer Dynamics Applications Engineer with the flat panel specifics. They will provide you with the appropriate information.

2.4 COM C and COM D Mode Selection (SF8, 9 and 12)

COM C and COM D are independently selectable as RS-232 or RS-422/RS-485 as shown in the following figure. The factory default is both UART’s are RS-232. Either or both can be converted to RS-422/RS-485 by moving the strap from RS-232 to RS-422/RS-485. SF8 and SF9 will enable or disable the Tx signal for RS-422 or RS-485 mode.

on - COM C is RS-232off - COM C is RS-485/422

on - COM D is RS-232off - COM D is RS-485/422

on - enable COM D 100 ohm terminating resistor in RS-485/422 modeoff - disable COM D 100 ohm terminating resistor in RS-485/422 mode(note: for RS-232 mode, leave strap off.)

Figure 2-9. SF12 Definition

The RTS signal on COM C and COM D is used to turn on and off the RS-422/RS-485 driver. The state of RTS is controlled by bit 1 of the UART Modem Control Register (MCR). When bit 1 of the MCR is set to a 0, the RS-422/RS-485 transmitters are on. When bit 1 of the MCR is set to 1, the RS-422/RS-485 transmitters are tri-stated. . Many of the communications programs, provided with a standard PC’s, do not toggle RTS correctly for RS-422/RS-485 operation with SBC-PII.

RS-422 requires that the driver be on at all times. If you are not writing your own communications program to control RTS, then you will want to disable the RTS signal from COM C and/or COM D by removing the shunt from SF8 and/or SF9.

RS-485 requires the RTS signal to control the driver so the shunt must be installed.

RS-232 also requires the RTS signal for signaling, so the shunt must be installed.

The factory default is both RTS signals is enabled (RS-232 default).



2.5 Fan Connector (J4 and J7)

Two fan connectors are provided one for the main processor fan (J4) and the other for system heat dissipation. The connectors include a fan tachometer to allow monitoring of fan operation providing ability to disable the system should a fan fail. The connectors are 3 x 1 Straight Locking 0.1” center headers.

INTRQ (pin 31) is IRQ 14 on J22 and IRQ 15 on J28.

To install two IDE hard disk drives on a single IDE connector, follow the instructions in the drive manufacturer's manual. Configure the first drive as the Master and the second drive as the Slave.

Some drives have shown intolerance to software reset (Ctrl-Alt-Del) and get "disk I/O error" on restart of WinNT. The fix for this is to disable multi-sector transfers in CMOS Setup.

2.20.1 Select IDE hard disk Type

Before SBC-PII can use the IDE hard disk drive, the BIOS must know the drive type. The BIOS on the SBC contains a setup utility for this purpose. See section 4.



2.20.2 Setting up a Hard Disk for use with MS-DOS

Before the IDE hard disk drive can be used by DOS, several setup steps must be completed. The first is low-level formatting. For all IDE hard disk drives purchased directly from CDI, low-level formatting will have been done prior to shipment.

Before the IDE hard disk drive can be used, it must be partitioned and formatted. The first of these steps is accomplished by booting the system from floppy and running the partition program FDISK.EXE (FDISK.COM on older versions of MS-DOS). FDISK is discussed in detail in Appendix D of the Microsoft MS-DOS User's Guide and User's Reference. We will not attempt to duplicate that discussion here but will guide you through the basics required to initialize your drive.

CAUTION: Partitioning a hard-disk will destroy any files that are on it.

With a diskette containing FDISK in your floppy drive, type

FDISK

and press the "Enter" key. FDISK will provide an option menu. Select the "Create DOS Partition or Logical DOS drive" option. On the next menu, select the "Create Primary DOS Partition" option. When the system asks if you want to use the maximum size DOS partition, answer "Y". The system will reboot afterwards, be sure to have a bootable floppy diskette in the floppy disk drive.

Once the drive has been partitioned, each partition must be formatted. For the primary partition, use the command:

FORMAT C: /S

to both format the partition and install a bootable copy of MS-DOS on the partition.

For any remaining partitions or drives, enter the command without the "/S" option (since they don't need MS-DOS). For example, the D: partition would be formatted with:

FORMAT D:

CAUTION: Always specify a drive when formatting to avoid accidentally losing valuable files by formatting the wrong drive.

Refer to the Microsoft MS-DOS User's Guide and User's Reference for details on the format process.

Once formatted with the "/S" option, you can complete the MS-DOS installation procedure provided with your copy of MS-DOS.



2.20.3 Setting up a Hard Disk for use with Windows 95™ or Windows 98™

Insert a Windows95™ or Windows98™ boot disk into the floppy disk drive and reboot your system. When the first screen appears press enter to continue the Windows™ installation. Select the “configure unallocated disk space” option, and press enter. The system will reboot automatically, and then format the hard disk for use with Windows™. When formatting is complete the installation program will continue to install Windows™.

2.21 Power Input (J23)

Power is applied to the SBC-PII through J23. This connector was selected to support the current requirements for SBC-PII. It includes a power return lead for each power connection which can help eliminate power lead related EMI.

The connector is an 8 x 1 straight locking 0.156” center square pin header.

2.22 Floppy Interface (J26)

The SBC-PII includes a 2.88MB floppy disk controller which supports two 360K/ 720K/ 1.2M/ 1.44M/2.88M floppy disk drives. A and B drives can be swapped.

It provides support for 3-Mode, enhanced digital data separation and software write protection. The board connector is a 17 x 2 straight locking 0.1” center header.

The drive cable for the SBC-PII is identical to that used in an IBM-PC. Wires 10 through 16 are swapped. This swap, or flip, provides the drive select to the drives. Attach drive A on the connector at the end of the cable. Drive B uses the middle connector on the cable. Set the straps or configuration switch on the drives so that both drives are configured as the second drive in the system. Note that 3.5" floppy drives require header-type connectors while 5.25" drives require card-edge connectors.

Figure 2-18. Floppy Drive Cable

The BIOS for the SBC-PII must be informed of the types of floppy drives attached to the system. This is accomplished using the BIOS Setup. See Section 3.1.



2.23 Keyboard Interface (J27)

The keyboard connector, J27 on the SBC-PII, is a 5 x 2 straight 0.1” center header. The connector provides an interface to PC/AT-compatible keyboards. It is 8042 compatible with 2KB programmable ROM and 256-byte data RAM.

A transistor is provided to drive a speaker or annunciator. Attach an 8- speaker (2" to 2.5" are typically used) to the keyboard cable as shown. Annunciators may be connected in place of the speaker. It will need to be connected to either the 5V supply or the 12V supply depending on the requirements of the particular device.

An IDE activity indicator LED may be connected to this cable as well.

Table 21 Interrupt Assignments

The industry standard IRQ assignments for COM C and COM D are IRQ4 and IRQ3 respectively. CMOS setup on SBC-PII follows this standard and defaults COM C and COM D as IRQ4 and IRQ3 when shipped from the factory. This causes a conflict in Windows95™ and WindowsNT™ because COM A and COM B claim those IRQ’s as well. Each COM port 'likes' its own IRQ.

To change the IRQ settings for COM C and COM D, first change the values stored in CMOS using the BIOS Setup Program (press F2 during POST before the operating system starts to load). Then change the IRQ settings in Windows95, Control Panel | System | Device Manager. In WindowsNT the setting can be changed in Control Panel | Ports. SBC-PII systems have a Plug & Play option that can be used for COM C and COM D eliminating need for hand configuration.

The PC industry has long felt a problem with too few interrupts and has developed USB as part of the plan to eliminate this problem



3.3 DMA Assignments

The SBC-PII DMA assignments are listed in the following tables. The SBC-PII supports PCI DMA with 3 PC/PCI channels and distributed DMA protocols simultaneously. It uses fast Type-F DMA for reduced PCI bus useage.

DMA Channels 0 through 3 support 8-bit transfers between 8-bit I/O devices and transfers between 8-bit or 16-bit memory. Each channel can transfer 64-kbyte blocks throughout the 16 Mbyte address range of the system on 64-kbyte boundaries. DMA Channel 4 is used to cascade DMA Channels 0 through 3. DMA Channels 5 through 7, support 16-bit transfers between 16-bit I/O and 16-bit memory. Each channel can transfer 128-kbyte blocks throughout the 32-Mbyte-address range of the system on 64 kbyte boundaries.

4.5 The Boot Menu

After you turn on your computer, it will attempt to load the operating system (such as Windows 95) from the drive of your choice. If it cannot find the operating system on that drive, it will attempt to load it from one or more other drives in the order specified in the Boot Menu.

Note:Specifying any drive as a boot drive on the Boot Menu requires the installation of an

operating system on that drive. To use another drive as a bootable drive may require your installing the operating system on it.

Selecting "Boot" from the Menu Bar displays the Boot menu, which looks like this:

[Yes] [No]

If you attempt to exit without saving, the program asks if you want to save before exiting and displays this message:

Setup WarningConfiguration has not been saved!

Save before exiting?[Yes] [No]

During bootup, Phoenix BIOS attempts to load the values saved in CMOS. If those values cause the system boot to fail, reboot and press <F2> to enter Setup. In Setup, you can get



the Default Values (as described below) or try to change the selections that caused the boot to fail.

4.6.2 Exit Discarding Changes

Use this option to exit Setup without storing in CMOS any new selections you may have made. The selections previously in effect remain in effect. Pressing <Enter> will exit Setup and reboot the computer.
