Software Configuration
3–9
You must also set hardware jumpers to configure the byte-wide sockets for the devices you install. Refer
to Chapter 2 for jumper positions. If you are using the byte-wide sockets for Solid State Disk (SSD),
using Ampro’s Solid State Disk software, follow the directions for setting the byte-wide sockets that are
in the SSD Technical Manual.
3.4.10 Expansion BIOS ROM Configuration
The Little Board/486i provides 16K bytes of Flash EPROM storage (part of the ROM BIOS device) for
the onboard Ethernet interface boot PROM. When enabled and properly programmed, it can be used to
boot from an Ethernet network server. This SETUP option enables or disables the boot PROM region at
CC000h–CFFFFh.
3.4.11 Serial Boot Loader Enable
This parameter enables or disables the Serial Boot Loader option in the Ampro ROM BIOS. The serial
boot loader allows you to boot from any of the onboard serial ports, much in the same way you would
boot from a local hard disk or from a LAN. A description of the Serial Boot Loader is provided in the
Ampro Common Utilities manual (in descriptions of SERLOAD and SERPROG), and in Ampro
Application Note AAN-9403. If you are not using the Serial Boot Loader, set this parameter to “Disable”.
3.4.12 Watchdog Timer Configuration
This parameter allows you to set the time duration of the watchdog timer for monitoring the boot process.
You can set it to 30, 60, or 90 seconds, or you can disable it.
Further information about the watchdog timer can be found later in this chapter under “Watchdog Timer.”
A description of the WATCHDOG utility program can be found in the Ampro Common Utilities manual.
3.4.13 Ethernet
These parameters control the Ethernet LAN interface on the Little Board/486i.
! Ethernet Enable/Disable—Use this parameter to enable or disable the Ethernet interface. When
disabled, the interface is set to E0E0h, an unused I/O port address.
! I/O Address—Set the I/O port base address of the controller. The default base address is 320h. You
can set it to 300h, 320h, 360h, or 380h.
! Interface—Select which connector (interface) you will use for your Ethernet media connection. The
choices are AUI or TP (twisted pair).
! IRQ—Select which IRQ to use. The default is IRQ9. The choices are IRQ3, IRQ9, IRQ10, or
IRQ11. (Note that the default IRQ for Serial 2 and Serial 4 is IRQ3, and the default IRQ for the SCSI
interface is IRQ11.)
Ethernet Node Address—The SETUP screen displays the node address of the onboard Ethernet
controller. This is just a display of the address. You cannot change it.
3.4.14 Local Bus Video Display
If you will be using a CRT display, select CRT. If you will be using a flat panel display, select FP. If you
will be using both types of display, select FP&CRT. If you select FP or FP&CRT, select a flat panel
display type (see below).
