One more rather interesting component is the additional BIOS chip in a special cradle.
In case the onboard BIOS happens to be damaged, this chip is simply put on top of the BIOS chip, thus the original BIOS is restored. Judging by the method of restore, this technology has been dubbed Top Hat Flash.
一个相当有意思的元件是放在座子里的一个附加BIOS芯片。一旦主板上的BIOS损坏,这个带芯片的座子放到板上的BIOS芯片上面,损坏的BIOS芯片可以修复。这一恢复方法技术上叫做叠装热刷新。
