建議緊急維修盤保持最新狀態(tài)，并易于訪問。VMIVME-7740在單個(gè)閃存設(shè)備中包括系統(tǒng)BIOS、視頻BIOS和LANWorks BIOS。VMIVME-7740內(nèi)存包括32 KB的非易失性靜態(tài)RAM（NVRAM），地址為$D8000至$DFFFF。除前24個(gè)字節(jié)外，其他所有字節(jié)均可訪問。字節(jié)$D8000-$D800D由看門狗控制器使用，包括系統(tǒng)命令寄存器（COMM）、VME BERR地址寄存器（VBAR）、VME-BERR地址修改寄存器（VBAMR）和板ID寄存器（BID）。本手冊第二卷對系統(tǒng)寄存器進(jìn)行了說明。CPU可隨時(shí)訪問NVRAM，并可用于存儲在斷電條件下不會(huì)丟失的系統(tǒng)數(shù)據(jù)（字節(jié)$D800E-$D8017為系統(tǒng)寄存器）
It is recommended that an emergency repair disk be kept up-to-date and easily accessible. The VMIVME-7740 includes the system BIOS, video BIOS, and LANWorks BIOS in a single flash memory device. The VMIVME-7740 memory includes 32 Kbyte of non-volatile static RAM (NVRAM) addressed at $D8000 to $DFFFF. All but the first 24 bytes are accessible. Bytes $D8000 - $D800D are used by the Watchdog controller and include the System Command Register (COMM), the VME BERR Address Register (VBAR), the VME BERR Address Modifier Register (VBAMR), and the Board ID Register (BID). The System registers are explained in Volume II of this manual set. The NVRAM can be accessed by the CPU at anytime, and can be used to store system data that must not be lost during power-off conditions (Bytes $D800E - $D8017 are the System Registers)
