RELIANCE 45C-410控制处理器
操作系统将继续以两个驱动器之间交替的方式向主分区分配驱动器号。接下来，将为逻辑分区分配驱动器字母，从第一个硬盘开始，依次为每个逻辑设备刻字，直到它们全部命名，然后在第二个硬盘上对每个逻辑分区进行相同的顺序刻字。注意：添加驱动器或更改初始分区方案导致的驱动器号更改可能会导致更改之前安装的操作系统出现问题。在安装操作系统之前计划您的配置以将困难降至最低。看门狗计时器VMIVME-7740使用Dallas DS1384看门狗计时控制器作为其看门狗计时器。该设备提供一天时间功能、看门狗警报和非易失性SRAM控制器。本节介绍了DS1384设备中的“每日时间”功能，但VMIVME-7740未使用该功能。VMIVME-7740使用的实际时间寄存器位于标准PC/at I/O地址。
The operating system will continue to assign drive letters to the primary partitions in an alternating fashion between the two drives. Next, logical partitions will be assigned drive letters starting on the first hard drive lettering each logical device sequentially until they are all named, then doing the same sequential lettering of each logical partition on the second hard disk. NOTE: Drive letter changes caused by adding a drive or changing the initial partitioning scheme may cause difficulties with an operating system installed prior to the changes. Plan your configuration prior to installing the operating system to minimize difficulties.Watchdog Timer The VMIVME-7740 uses a Dallas DS1384 Watchdog Timekeeping Controller as its Watchdog Timer. The device provides a Time of Day feature, a Watchdog Alarm and a Non-Volatile SRAM controller. The Time of Day feature found within the DS1384 device is explained in this section, but is not utilized by the VMIVME-7740. The actual Time of Day registers used by the VMIVME-7740 are located at the standard PC/AT I/O address.
