RELIANCE 45C-410控制處理器
操作系統(tǒng)將繼續(xù)以兩個驅(qū)動器之間交替的方式向主分區(qū)分配驅(qū)動器號。接下來，將為邏輯分區(qū)分配驅(qū)動器字母，從第一個硬盤開始，依次為每個邏輯設(shè)備刻字，直到它們?nèi)棵?，然后在第二個硬盤上對每個邏輯分區(qū)進(jìn)行相同的順序刻字。注意：添加驅(qū)動器或更改初始分區(qū)方案導(dǎo)致的驅(qū)動器號更改可能會導(dǎo)致更改之前安裝的操作系統(tǒng)出現(xiàn)問題。在安裝操作系統(tǒng)之前計劃您的配置以將困難降至最低。看門狗計時器VMIVME-7740使用Dallas DS1384看門狗計時控制器作為其看門狗計時器。該設(shè)備提供一天時間功能、看門狗警報和非易失性SRAM控制器。本節(jié)介紹了DS1384設(shè)備中的“每日時間”功能，但VMIVME-7740未使用該功能。VMIVME-7740使用的實際時間寄存器位于標(biāo)準(zhǔn)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.
