Can't boot ReactOS 0.2.5-xbox #248
Description
Issue
ReactOS 0.2.5-xbox does not boot to desktop in XQEMU.
Setup
- A custom Cromwell 2.41-dev BIOS (also XBE mirror download)
- ReactOS 0.2.5-xbox file tree (.tar.gz)
- ReactOS 0.2.5-xbox image (.qcow2 ready for XQEMU, legitimately created using xboxhdm, shared in the XboxDev Discord)
This setup is confirmed working (boots to desktop) on real Xbox 1.0, 1.1 and 1.4.
Description
In the XQEMU it crashes with unhandled page fault exception in the kernel in xboxvmp.sys driver.
I found that it crashes in XboxVmpMapVideoMemory when accessing nVidia controller to tell about the framebuffer (this function is called on IOCTL_VIDEO_MAP_VIDEO_MEMORY):
