Now the board can boot Ubuntu and Windows 7. But it failed to boot Windows 8.<br>
It crashes at a very early stage, which seems to be Windows bootloader. The debug message of SeaBIOS is attached.<br>
<br>
The interrupt routine installed by SeaBIOS still work. We can see handle_13, handle_08, handle_1a are called once in a while.<br>
There is no BSOD. There is only a windows logo on the monitor, without progress ring of Windows 8.<br>
Even the debug version of windows 8 doesn't help, because it crashes before the image is loaded.<br>
<br>
Is there any more way to debug windows 8 bootloader?<br>
