Hi, I have an ACER Extensa 4420 laptop. Original BIOS V1.17

Recently I opened by mistake a file (virus) that burned my BIOS and prevented my laptop from booting with any O.S. or internal/external source.

I tried to boot with an old win 98 CD, and downloaded with another lap the BIOS files V1.18 from the Acer website (ABVXD.VDX - FLASH.SYS - OTA118.exe) , but I can not use it in DOS mode. So I managed to get an USB pen drive with portable XP os, but now the problem is that the executable file (OTA118.exe) says that there is not enough battery or external power to continue. (The battery is new and its plugged in.

How can I burn the BIOS??

OTA118.exe it's supposed to flash the bios from windows. I've read that Acer usually uses Winplash, but not in this case.

The problem is that with a usb portable xp I can't install Winplash and use it. And it just wont boot with any hard disk because it turns them off when they try to start windows.

Please, I need help!
