PCI-ISA Bridge Mapping
The ETX-PVR supports ISA bus based modules with an on-board PCI-ISA bridge. The PCI-ISA bridge
optionally maps the IRQs to ISA based modules.
The ETX-PVR system BIOS, maps resources based on information provided in the BIOS Setup screens. By
default, IRQs to be mapped to ISA modules must be explicitly specified by the user in the BIOS Setup
screens.
The IRQs 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”.
Logo Screen Utility (Splash Screen)
The ETX-PVR BIOS supports a graphical logo utility, 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. 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.
Logo Screen Image Requirements
The user’s image may be customized with any image editing tool, and the system will automatically convert
the image into an acceptable format to the tools (files and utilities) provided by ADLINK.
