Hello,
I recently got into the scene and following the tutorials have had a lot of success (THANK YOU CALAMITY!!!). I got things mostly setup the way I want, and decided I was tired of turning the TV on and off on reboots. Took the plunge on Atom-15 install and was struggling to get the MS-DOS USB bootable drive to work. I usually don't have much trouble following software guides, but no matter what I did I couldn't get it to work. Specifically I got what appeared to be success from the feedback I got from the HP USB format tool suggested in the ATOM-15 guide link. I then dragged all of the files (ATIflash and files provided in the links) onto the drive. When I restarted and booted from the drive I got just a curser in the upper left hand corner. On one occasion I got some feedback on screen that I didn't capture with my camera and couldn't seem to repeat. I tried reformatting and dragging just the atiflash.exe, and same results.
In a bit of frustration I decided to go the ATIwinflash route. Everything seemed to go fine, and I got the feedback that the new bios was installed. When I restarted my computer I got no signal from the card. I ordered a cheap ATI card to get back into the system only to find that I could't use ATIwinflash to get the R7 back to it's original bios, got an error message every time. It seemed to be able to work with just the new ATI card, but with two installed it wouldn't work.
This leads me to believe I need to go the MS-DOS route, but for the life of me I can't figure out what I'm doing wrong that I get nothing when booting from the USB drive.
Thanks in advance for the help!
