I downloaded the zip file you attached to a USB flash drive using my desktop computer. From there I copied it to my root C: drive on my Fiva. I then rebooted my Fiva into a DOS prompt only.
I ran Awd621.exe and it displayed the screen you showed above. For the "name to program", I entered nothing and hit ENTER. Then it prompted me to make a backup of my BIOS, which I selected "Y" and gave it a file name. It created a bios file. It was about 261K in size.
Then I ran Awd753 and repeated the same process. I gave a different name, and it saved a file about 128mb in size. Like your examples above, a program error was generated when it couldn't locate the source file to flash the BIOS image from. But it exited back to DOS fine.
Two different BIOS images from the same machine...strange. Anyways, I then went to reboot my Fiva back into Win98 so I could copy the two files back to my flash drive so I could send them to you on my desktop machine.
My Fiva is now a brick....let me repeat that....A BRICK!
It will not boot, it will not post, it will not do anything... When I power on, I can hear the hard drive spin up...and then nothing. Nothing on the screen...nothing at all. And, I cannot turn it off now either, unless I pull the battery and unplug the a/c adapter.
It seems I have turned a great little touchscreen handheld into a piece of JUNK!
You can imagine how I am feeling right now....
