PCI-to-ISA Bridge Mapping
The LittleBoard 735 supports ISA bus based modules with an on-board PCI-to-ISA bridge. The PCI-to-ISA
bridge optionally maps the following resources to ISA based modules:
• IRQs
• DMA Channels
The LittleBoard 735 system BIOS, maps the above resources based on information provided in the BIOS
Setup screens. By default, IRQs or DMA channels to be mapped to ISA modules must be explicitly specified
by the user in the BIOS Setup screens.
The IRQs and DMA channels are mapped with the “PCIPnP/IRQx” fields in BIOS setup (where x specifies
the IRQ number.) The IRQs 3, 4, 5, 7, 9, 10, 11, 14, and 15 can be mapped to ISA based modules by
changing the default setting for these IRQs from “Available” to “Reserved”.
Any of the DMA channels 0, 1, 3, 5, 6, 7 can be mapped to ISA modules by changing the default setting of
“Available” to “Reserved”.
Logo Screen Utility (Splash Screen)
The LittleBoard 735 BIOS supports a graphical logo utility, which can be customized by the user and
displayed 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. The custom image can be displayed as the
first image displayed on screen during the boot process and remain there, depending on the options selected
in BIOS Setup, while the OS boots.
