This page describes the plan of reviving the ReactOS port for the original Xbox, including components outside the source tree.

Once something is done in this list, it should be simply removed.

Revive ReactOS Xbox port

Progress is tracked in CORE-16216.

Fix ReactOS bugs

  • Fix USB OHCI - CORE-16352
    • Blocks actual OS testing in XQEMU
    • Reproduced on RealHW as well
  • Fix USBH_ProcessHubStateChange: OverCurrent problem - CORE-16726
    • RealHW only
  • Fix PCI-to-PCI bridge PnP problem - CORE-16319
    • RealHW only, applied workaround in master - b992727
  • Fix FindResourceExW debug print problem (low priority)
    • Too hard to reproduce
  • Assertion failed: (pti->pcti->fsChangeBits & QS_SENDMESSAGE) == 0 happens in win32ss/user/ntuser/misc.c, line 729 after some idle hours, and it can be safely cont'ed from kernel debugger
    • Does not happen with usbohci.sys from Windows 2003 for some reason
  • Bug with INBV rotation bar on 720x480 resolution (draws outside the frame)
  • Xbox HAL: Shutdown does not happen, shows "It is now safe to turn off your computer" picture
  • Serial COM1 is not accessible for user-mode, the port can be opened, but both RX and TX are ignored - FIXME: needs ticket
    • RealHW only, the debug port lacks SERIRQ, so it cannot utilize interrupt
  • When installed with bootcd to HDD in XQEMU, C: drive letter is assigned to DVD-ROM, and D: letter is assigned to the system drive - CORE-15575
  • XGPU PCI device is not reported/detected by pci.sys driver (minor problem) - FIXME: needs ticket
    • RealHW only

Improve ReactOS

  • Add Xbox machine detection into setuplib - FIXME: needs ticket
  • Add bootvid selection into txtsetup.sif and setuplib - FIXME: needs ticket
  • Add missing devices into Xbox HAL device tree:
    • PIC (*PNP0000)
    • Timer (*PNP0100)
    • DMA Controller (*PNP0200)
    • Speaker (*PNP0800)
    • CMOS/RTC (*PNP0B00)
  • Xbox HAL: Serial COM ports and other LPC devices should be children of ISA to PCI bridge
  • Xbox HAL: Think about exposing LPC SuperIO controller (I/O ports 0x2E-0x2F) if it's detected
  • Xbox HAL: Report reserved video memory range for NVIDIA NV2A (use "NV2A Framebuffer" resource added earlier, maybe as *PNP0C02 aka "Motherboard resources") - FIXME: needs ticket
  • Xbox HAL: Report Flash ROM memory range as *PNP0C02 aka "Motherboard resources" (0xFF000000 - 0xFFFFFFFF)
  • Add automatic HAL selection in FreeLdr - FIXME: needs ticket
    • Will allow to test bootcd and livecd
  • Add support for Xbox BRFR partitions - CORE-16329
    • Requires disk_new driver - CORE-6264
    • Blocks testing on real hardware
  • Fix or implement FATX filesystem driver - CORE-16373
    • FATX support should be removed from fastfat, or not, if we switch to fastfat_new (but when?) - CORE-11819
    • Blocks testing on real hardware
  • Add input support in FreeLdr on Xbox - CORE-16218 (low priority)
    • freeldr.ini can be modified manually
  • Add HAL/video/bootvid sections into unattend.inf - FIXME: needs ticket

Implement missing drivers

Fix bugs and improve Cromwell

  • Fix glitchy text characters: . _ ( f
  • Fix boot device label positioning (in 720x480 and 1024x576 screen mode)
  • Fix Xromwell XBE problems on some Xbox'es (at least the one JayFoxRox have)
  • Add SMBIOS table generation
    • Check corresponding data on NVIDIA nForce 420 board
  • Add PCI BIOS table generation
    • Check corresponding data on NVIDIA nForce 420 board
  • Import features from XBOverclock project
  • Add full device information page for Peripherals menu (low priority)
  • Other published issues:
