【原创】2011年下半年即将上市惠普SNB笔记本新特性: 零风险刷新BIOS

注: 此功能(BIOS F10内置刷新程序代码)早在6年前(2005年)惠普商用高端台式机dc7600上就已经实现!

何为零风险？

只有主板上有2个bios芯片才能实现0风险

ls的认知还停留在双芯片bios时代

其实现在的技术已经是一个芯片里面可以有两个bios的存储区域了，类似于硬盘的raid1效果

BootBlock Emergency Recovery Mode

Most Hewlett-Packard desktop systems include 64 KB of write-protected boot block ROM that provides a way to recover from a failed flashing of the system BIOS ROM.BootBlock Emergency Recovery Mode will boot the PC in a recovery mode and search the root directory of the removable media sources (floppy, USB, or CD) for a compatible binary image.The BIOS CD Media file, included in the softpaq, should be used to create a BIOS image CD if the user or administrator desires to use CD media for BIOS recovery.When flashing during recovery, the CD media, containing the BIOS image file, must be El-Torito compatible.Floppy or USB media sources can simply contain the BIOS binary image file in the root directory.   Once a binary image is located, the BIOS update process will be attempted again.The automatic flash recovery will continue until the BIOS is successfully updated or restored.If no binary image is found, the system will attempt to boot to diskette or USB flash media.The boot media must have DOS in order for the disaster recovery mode to successfully boot.
