I'm not sure if this is video controller issue. Maybe you can try another driver.
Rick, Did you find any resolution to this? I am having the exact same issue. I received my first R400 today and after it's done with the image, it reboots, then a black screen.
Thanks Jan. I did attempt the Halconfig without success, BUT, I did find a solution.
I took the XP CD that I used to create my image and installed the OS from the CD. Once installed, I looked at what the processor was using for a driver (Device Manager --> Computer --> Right click on Processor and go to Properties --> Driver --> Driver Details). It was using the following files:
I then copied those three files to my jump drive. Used Windows PE to dump the image back on the R400. After the dump, I used diskpart to enable it to be readable (No reboot required). I then copied those three files to C:\windows\system32. Rebooted the computer and WaLa. Fixed.
Was it the new HalConfig that you tried (the one that comes with HII V9.1)? And did you use the /cab=sp3.cab parameter? If the machine is montevino based and you used the old halconfig, or you used the new one but neglected to use the /cab parameter, you will indeed have problems.
FYI, other people have told me they successfully used halconfig V2.x with an R400.
If there is a valid reason to provide your own HAL files, there is a way to do so: create a hal subfolder in your machine specific driver folder and put the HAL files of your choice in it (see page 37 of the HII document, V9.1).
