Asus Ez Flash 2 Driver
Format a usb pen drive to FAT-16 partition. 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. Copy 1301.rom to its root folder and rename it to 1005HA.ROM.

The reason for renaming it to 1005HA.ROM is that EZ Flash on this 1001HA netbook looks up rom with this name. 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.
