VMIVME-7700-110000 超低电压Intel 具有板载设置程序

VMIVME-7700-110000具有板载BIOS设置程序，可控制许多配置选项。这些选项保存在一个特殊的非易失性、电池支持的存储芯片中，统称为板的“CMOS配置”。CMOS配置从施加功率的那一刻起就控制与硬件行为有关的许多细节。VMIVME-7700-110000出厂时，CMOS中的硬盘驱动器类型配置设置为AUTO。VMIVME-7700-110000 BIOS设置程序的详细信息包含在附录C中。

VMIVME-7700接受一个144引脚SDRAM SODIMM，最大容量为512兆字节。板载DRAM通过PCI到VMEbus桥与VMEbus共享，可由本地处理器寻址，也可由另一个VMEbus主控器寻址VMEbus从接口。

在本地处理器和VMEbus之间共享内存时必须小心，以防止VMEbus主机覆盖本地处理器内存的关键区域（如操作系统）。VMIVME-7700包括32K字节的非易失性SRAM，CPU可以随时访问，用于存储在断电条件下不得丢失的系统数据。

The VMIVME-7700-110000 has an onboard BIOS setup program to control many configuration options. These options are stored in a special non-volatile, battery-supported memory chip, collectively known as the board's "CMOS configuration." CMOS configurations control many details related to hardware behavior from the moment power is applied. When the VMIVME-7700-110000 is shipped, the hard drive type configuration in CMOS is set to AUTO. Details of the VMIVME-7700-110000 BIOS setup program are included in Appendix C.

The VMIVME-7700 accepts a 144-pin SDRAM SODIMM with a maximum capacity of 512 megabytes. The onboard DRAM is shared with the VMEbus via the PCI to VMEbus bridge and can be addressed either by the local processor or by another VMEbus master to address the VMEbus slave interface.

Care must be taken when sharing memory between the local processor and the VMEbus to prevent the VMEbus host from overwriting critical areas of the local processor's memory (such as the operating system). The VMIVME-7700 includes 32K bytes of non-volatile SRAM, which the CPU can access at any time, for storing system data that cannot be lost in the event of a power outage.
