产品详细资料
物理存储器VMIVME-7740提供同步DRAM(SDRAM)作为板载系统存储器。内存可以以字节、单词或长单词的形式访问。VMIVME-7740上的所有RAM都通过PCI到VME桥双端口到VMEbus。内存可由本地处理器寻址,也可由另一个VMEbus主机寻址VMEbus从属接口。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的操作系统。注意:在Windows NT 4.0中使用I/O Works Access的Configure实用程序配置RAM时,请不要请求超过25%的物理RAM。超过25%的限制可能会导致已知的Windows NT错误。这可能会在Windows NT启动过程中导致不可预测的行为,需要使用紧急修复盘来恢复计算机。Windows NT 4.0 service pack级别3中存在此错误。建议紧急维修盘保持新状态,并易于访问。
Physical Memory The VMIVME-7740 provides Synchronous DRAM (SDRAM) as on-board system memory. Memory can be accessed as bytes, words, or longwords. All RAM on the VMIVME-7740 is dual-ported to the VMEbus through the PCI-to-VME bridge. The memory is addressable by the local processor, as well as the VMEbus slave interface by another VMEbus master. Caution must be used when sharing memory between the local processor and the VMEbus to prevent a VMEbus master from overwriting the local processor’s operating system. NOTE: When using the Configure utility of I/O Works Access with Windows NT 4.0 to configure RAM, do not request more than 25 percent of the physical RAM. Exceeding the 25 percent limit may result in a known Windows NT bug. This may cause unpredictable behavior during the Windows NT boot sequence, requiring the use of an emergency repair disk to restore the computer. The bug is present in Windows NT 4.0 service pack level 3. It is recommended that an emergency repair disk be kept up-to-date and easily accessible.
