系统引导中硬盘还原卡预警功能的实现

Realization of alarm function in hard-disk restorable card on system booting

针对硬盘还原卡在自身损坏情况下无法预警,造成计算机保护丧失,增加机房维护难度的现实情况,提出改进意见,并给出汇编语言的示例设计代码.通过对具体产品的应用测试表明,使用本方法能切实提高板卡的自适应能力,做到及时预警,实现硬盘还原卡损坏情况下的开机智能判断与处理.

In this paper, aiming at the realities of losing safeguard in computer and increasing difficulties in maintenance when the common harddisk restorable card was bad, an improved method was put forward Example codes in ASM program were also given. The actual tests indicates that the selfsuitable ability of the card can be really improved by using this method, and at the same time, the card can accomplish selfcheck and give an alarm in case of damages when computer is power on.
