用户应用程序可以覆盖BIOS设置的配置并重新配置系统,或者它可以接受BIOS初始化的内容。BIOS控制概述VMIVME-7740上有两个用户必须熟悉的区域,以便覆盖初始BIOS配置:设备地址和设备中断。本附录回顾了这些地址和中断的详细信息,并提供了板上使用的单个设备的参考列表。VMIVME-7740利用高性能外围组件互连(PCI)总线以及工业标准体系结构(ISA)总线。通常,PCI总线是即插即用兼容的。连接到PCI总线的组件不总是位于标准I/O或内存地址,也不连接到ISA总线设备的标准中断请求线。这些PCI总线设备由BIOS重新建立,这意味着每次CPU启动时,这些设备不会总是位于同一地址或连接到同一中断请求线。
A user application may override the configuration set by the BIOS and reconfigure the system, or it may accept what the BIOS initialized. BIOS Control Overview 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.
