本手册第3章介绍了默认中断向量表和默认地址映射。***,BIOS跳转到硬盘驱动器或软盘驱动器以执行操作系统的引导程序。这是自定义操作系统可以控制板并继续进行自定义配置和/或自定义应用程序的点。用户应用程序可以覆盖BIOS设置的配置并重新配置系统,也可以接受BIOS初始化的内容。VMIVME-7740上有两个用户必须熟悉的区域,才能覆盖初始BIOS配置:设备地址和设备中断。本附录审查了这些地址和中断的详细信息,并为电路板上使用的各个设备提供了参考列表。VMIVME-7740利用高性能外围组件互连(PCI)总线和工业标准体系结构(ISA)总线。通常,PCI总线是即插即用兼容的。连接到PCI总线的组件并不总是放置在标准I/O或内存地址,也不像ISA总线设备那样连接到标准中断请求行。这些PCI总线设备由BIOS重新建立,这意味着每次CPU启动时,这些设备不会始终位于同一地址或连接到同一中断请求行。本附录列出了通电特定VMIVME-7740时发现的默认值。

The default interrupt vector table and the default address map are described in Chapter 3 of this manual. Finally, the BIOS jumps to the hard drive or floppy drive to execute the operating system’s boot program. This is the point at which a custom operating system may take control of the board and proceed with a custom configuration and/or custom application. A user application may override the configuration set by the BIOS and reconfigure the system, or it may accept what the BIOS initialized.There are two areas on the VMIVME-7740 in which the user must be familiar in order to override the initial BIOS configuration: the device addresses and the device interrupts. This appendix reviews the details of these addresses and interrupts, and provides a reference list for the individual devices used on the board. The VMIVME-7740 utilizes the high-performance Peripheral Component Interconnect (PCI) bus along with the Industrial Standard Architecture (ISA) bus. In general, the PCI bus is plug-and-play compatible. The components that are connected to the PCI bus are not always placed at a standard I/O or Memory address, nor are they connected to a standard interrupt request line as is the case with ISA bus devices. These PCI bus devices are re-established by the BIOS, meaning that these devices will not always be located at the same address or connected to the same interrupt request line every time the CPU is booted. This appendix lists the defaults that are found by powering up a specific VMIVME-7740.
