用戶應(yīng)用程序可以覆蓋BIOS設(shè)置的配置并重新配置系統(tǒng)，或者它可以接受BIOS初始化的內(nèi)容。BIOS控制概述VMIVME-7740上有兩個(gè)用戶必須熟悉的區(qū)域，以便覆蓋初始BIOS配置：設(shè)備地址和設(shè)備中斷。本附錄回顧了這些地址和中斷的詳細(xì)信息，并提供了板上使用的單個(gè)設(shè)備的參考列表。VMIVME-7740利用高性能外圍組件互連（PCI）總線以及工業(yè)標(biāo)準(zhǔn)體系結(jié)構(gòu)（ISA）總線。通常，PCI總線是即插即用兼容的。連接到PCI總線的組件不總是位于標(biāo)準(zhǔn)I/O或內(nèi)存地址，也不連接到ISA總線設(shè)備的標(biāo)準(zhǔn)中斷請(qǐng)求線。這些PCI總線設(shè)備由BIOS重新建立，這意味著每次CPU啟動(dòng)時(shí)，這些設(shè)備不會(huì)總是位于同一地址或連接到同一中斷請(qǐng)求線。
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.
