Holes for a right angle mounting header are also available at J19. All the onboard voltages are derived from the externally supplied +5 volts DC +/- 5%.
Chapter 4 BIOS Setup Introduction This chapter describes the BIOS Setup Utility menus and the various screens used for configuring the LittleBoard 800. Some features in the Operating System or application software may require configuration in the BIOS Setup screens. This section assumes the user is familiar with BIOS Setup and does not attempt to describe the inner workings of BIOS functions. Refer to the appropriate PC reference manuals for information about the onboard ROM-BIOS software interface.
Chapter 4 BIOS Setup Accessing BIOS Setup (Serial Console) Entering the BIOS Setup, in serial console mode, is very similar to the steps you use to enter BIOS Setup with a VGA display, except the actual keys you use. 1. Set the serial terminal, or the PC with communications software to the following settings: ♦ 115k baud ♦ 8 bits ♦ One stop bit ♦ No parity ♦ No hardware handshake 2.

Chapter 4 BIOS Setup • Boot Order ♦ Boot 1st – [none], [Drive A], [Drive B], [Drive C], [Drive D], [CDROM], [Alarm], or [Reboot] ♦ Boot 2nd – [none], [Drive A], [Drive B], [Drive C], [Drive D], [CDROM], [Alarm], or [Reboot] NOTE The [Alarm] option sounds beeps on the PC speaker and can be listed, like [Reboot], as the last boot device to indicate no bootable device was found. Any of the drives can be listed as a boot drive.
Chapter 4 BIOS Setup NOTE This feature allows you to use any one of the three common formats available for CompactFlash cards without having to re-format the CompactFlash card before you can use it on the LittleBoard 800. The LBA (Logical Block Address) is set as the default format because it can handle larger drives and is the newest format available, but may not be the one used to format your CompactFlash card.
Chapter 4 BIOS Setup ♦ Splash Screen – [Disabled] or [Enabled] The Splash Screen is a graphical image displayed as the default (Ampro Splash Screen) or a user customized image on screen. Refer to the Splash Screen Customization topic later in this chapter for instructions on how to customize the splash screen. ∗ If Splash Screen is [Enabled] it stays on screen, until the booted Operating System changes it, if the Config Box option is Disabled.
Chapter 4 BIOS Setup ♦ Watchdog Timeout (sec) – [select whole number between 1 and 255 seconds, in 1-second increments] or [Disabled] If this field is enabled by selecting a time interval (1 to 255 seconds), will direct the watchdog timer to reset the system if it fails to boot the OS properly. Refer to the watchdog timer section in Chapter 3 for more information.
Chapter 4 BIOS Setup ♦ LAN Boot – [Disabled] or [LAN1] This field allows you to boot the system over one of the Ethernet connections (LAN1, J23). Refer to Appendix B, LAN Boot Feature and the BIOS settings for the integrated PXE Boot Agent for more information. ∗ If this field is set to [LAN 1], the LittleBoard 800 will boot from Ethernet 1 (J23). If you enable LAN Boot [LAN 1], you will need to save changes and reboot the system, before going to the PXE BIOS settings.
Chapter 4 BIOS Setup ♦ Serial 4 – [Disabled], [3F8h], [2F8h], [3E8h], [2E8h], [260h], [3E0h], [2E0h], [200h], [220h], [228h], [238h], or [338h] This field specifies the base address used for Serial Port 4. • IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15] This field specifies the IRQ used for Serial Port 4. If this field is set to [none], then no IRQ is assigned, making it available for other devices.
Chapter 4 BIOS Setup Video and Flat Panel Options • On-Board Video ♦ Framebuffer Size – [Disabled], [1MB], [4MB], [8MB], [16MB], or [32MB] This field specifies the amount of system memory used for the on-board Video Framebuffer. The amount of memory used for the Framebuffer of the on-board Video controller is subtracted from the available system memory. ♦ AGP Aperture Size – [64MB], [128MB], or [256MB] This field specifies the size of memory used for the AGP Aperture.
Chapter 4 BIOS Setup PCI, Plug n' Play, and Interrupt/DMA Assignments • PCI ♦ INTA IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15] ♦ INTB IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15] ♦ INTC IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15] ♦ INTD IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12], [14], or [15] ♦ INTE IRQ – [none], [1], [3], [4], [5], [6], [7], [9], [10], [11], [12],
Chapter 4 BIOS Setup ♦ Assign IRQ 6 – [Disabled] or [Enabled] (Typically Floppy Disk) ∗ If this field is set to [Enabled], then the BIOS can assign this IRQ to a Plug and Play adapter. ∗ If another device in the system is using this IRQ, then this field should be set to [Disabled]. ♦ Assign IRQ 7 – [Disabled] or [Enabled] (Typically LPT1) ∗ If this field is set to [Enabled], then the BIOS can assign this IRQ to a Plug and Play adapter.
Chapter 4 BIOS Setup ♦ Assign DMA 0 – [Disabled] or [Enabled] ∗ If this field is set to [Enabled], then the BIOS can assign this DMA channel to a Plug and Play adapter. ∗ If another device in the system is using this DMA channel, then this field should be set to [Disabled]. ♦ Assign DMA 1 – [Disabled] or [Enabled] ∗ If this field is set to [Enabled], then the BIOS can assign this DMA channel to a Plug and Play adapter.
Chapter 4 BIOS Setup Splash Screen Customization The LittleBoard 800 BIOS supports a graphical splash screen, which can be customized by the user and displayed on screen when enabled through the BIOS Setup Utility. The graphical image can be a company logo or any custom image the user wants to display during the boot process.
Chapter 4 BIOS Setup Use the following steps to convert and load your custom image onto the LittleBoard 800. 1. Copy the files from the LB800\software\examples\splash directory on the CD-ROM to a new directory (conversion directory) on your PC. This new conversion directory is where you intend to do the conversion and save the file. 2. Remove the read-only attributes from all the files as part of the file copying process. 3. Copy the LittleBoard 800 BIOS binary file (lb800.
