On Windows 7, 8, or 10, hit Windows R, type “msinfo32” into the Run box, and then hit Enter.
The BIOS version number is displayed on the System Summary pane. Different motherboards use different utilities and procedures, so there’s no one-size-fits-all set of instructions here.
From there, you choose the BIOS-updating option, select the BIOS file you placed on the USB drive, and the BIOS updates to the new version.
You generally access the BIOS screen by pressing the appropriate key while your computer boots—it’s often displayed on the screen during the boot process and will be noted in your motherboard or PC’s manual. The process for entering a UEFI setup screen can be a bit different.
Remember all that "Create a DOS boot CD, run the flasher" rubbish? The Asus EZ-Flash system lets you flash directly from a USB stick (or, possibly, other media - but as the 1215N only has a USB port, it's the one we're using).
The trick is that if you try it, it probably won't work. EZ-Flash seems to require a hideous FAT16 filesystem to function.
Fortunately, updating the BIOS is easy - once you know the trick.This will render your computer unbootable—it’ll be “bricked.” Your computer’s BIOS version is displayed in the BIOS setup menu itself, but you don’t have to reboot to check this version number.There are several ways to see your BIOS version from within Windows, and they work the same on PCs with a traditional BIOS or a newer UEFI firmware. Copy 1301to its root folder and rename it to 1005HA. If EZ flash failed saying trying to find a rom file with another name, just shutdown the netbook and rename your rom file to the required name and try again.4. Make sure that during the ASUS splash screen, press ALT F2. In my case I used a 32 MB SD card which came with my old Kodak camera, and I used a SD card reader that PC can see it as a usb disk. ROM is that EZ Flash on this 1001HA netbook looks up rom with this name.701 looks like it is specifically aimed at Windows 8 support.
