BIOS Recovery by Crisis Disk

BIOS Recovery Boot Block

The BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. Users can enable this feature to restore the BIOS firmware to the factory settings if a BIOS flash process fails.

BIOS Recovery Hotkey

The system provides a function hotkey: Fn+Esc, to enable the BIOS Recovery process when a system is powered on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot Block.

Steps for BIOS Recovery from USB Storage

Before performing this procedure, prepare a Crisis USB key. The Crisis USB key can be made by executing the Crisis Disk program in a functioning system with a Windows XP or Vista OS.

IMPORTANT:The Crisis Disk program will overwrite all data on any drive that you use as a crisis disk. Follow the steps below:

  1. Modify the archive name from "zh7 bios" to "ZH7X64.fd"
  2. Save ROM file (file name: ZH7X64.fd) to the root directory of the USB storage.
  3. Plug the USB storage into a USB port.
  4. Press Fn + ESC button then plug in AC. The Power button flashes once.
  5. Press Power button to initiate system CRISIS mode.

When CRISIS is complete, the system auto restarts with a workable BIOS.

6. Update the latest version BIOS for this machine by the regular BIOS flashing process.

    Where do I get the Crisis Disk program? I am trying to recover the bios on my acer 1810tz... Also, in your step 4), you say press Fn + ESC then plug in AC. When I do that, the power button does not flash... Do you mean press Fn + ESC and then press the power button (with Fn + ESC still held down)?
