RELIANCE 45C951可編程控制器編程器
如前所述，典型的系統(tǒng)包括VMIVME-7740，其駐留的閃存磁盤(pán)配置為次要IDE設(shè)備、連接到主要IDE接口的硬盤(pán)驅(qū)動(dòng)器和連接到軟盤(pán)接口的軟盤(pán)驅(qū)動(dòng)器。使用此配置，可能需要將任一IDE設(shè)備上的邏輯設(shè)備配置為可引導(dǎo)設(shè)備，從而允許通過(guò)BIOS功能設(shè)置屏幕選擇引導(dǎo)順序。使用此功能，用戶(hù)可以使系統(tǒng)配置有多個(gè)操作系統(tǒng)（OS），然后可以通過(guò)將IDE邏輯設(shè)備分配為引導(dǎo)設(shè)備來(lái)選擇這些操作系統(tǒng)。DOS實(shí)用程序FDISK通常用于配置硬盤(pán)驅(qū)動(dòng)器上的分區(qū)結(jié)構(gòu)。其他實(shí)用程序可用于執(zhí)行此任務(wù)。PowerQuest的Partition Magic是一款受歡迎且功能強(qiáng)大的商用程序。以下評(píng)論與使用FDISK進(jìn)行分區(qū)有關(guān)。注意：刪除分區(qū)將擦除該分區(qū)中以前保存的所有數(shù)據(jù)。
As discussed earlier, a typical system consists of the VMIVME-7740 with its resident Flash Disk configured as the Secondary IDE device, a hard drive attached to the Primary IDE interface, and a floppy drive attached to the floppy interface. Using this configuration, it may be desirable to have a logical device on either IDE device configured as a bootable device, allowing the selection of the boot sequence via the BIOS Features Setup screen. Using this capability, a user could have a system configured with multiple operating systems (OS’s) that would then be selectable by assigning the IDE logical device as the boot device. The DOS utility FDISK is commonly used to configure the partition structure on a hard drive. Other utility programs are available for performing this task. Partition Magic by PowerQuest is a popular and capable commercially available program. Comments that follow pertain to partitioning efforts using FDISK. CAUTION: Deleting a partition will erase all the data previously held in that partition.
