Xbox Port Roadmap

This page describes the plan of reviving ReactOS port for 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
  • Important: check whether the problem is reproduced on real Xbox
• 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
• Fix XBOX_IDE_CONTROL_PORT, it should be 0x3F6 (primary channel) instead of 0x170 (secondary channel), see links: [1], [2], [3]

Improve ReactOS

• Obtain memory map via multiboot on Xbox - CORE-16300, PR #1971
  • Will allow bootvid and xboxvmp to work properly
  • Will allow firmware to prepare SMBIOS/PCI BIOS tables in memory
• Add bootvid selection into txtsetup.sif and setuplib - FIXME: needs ticket
  • See chat message from Hermes Belusca
• Fix Xbox HAL to report reserved video memory range for NVIDIA NV2A - FIXME: needs ticket
  • See chat message from Thomas Faber
• Add ATAPI support into FreeLdr - CORE-16220
  • Will allow to test bootcd and livecd
  • Could be useful for PC-98 port as well
• 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

Documentation

• Fix constants and variables naming in freeldr and xboxvmp from Xbox-Linux to MS (low priority)

Implement missing drivers

• Add bootvid driver for Xbox - CORE-16219
  • Nice for public demonstration and user experience
• Add vgasave driver for NVIDIA NV2A - FIXME: needs ticket
  • See chat message from r3mendozal
• Add NVIDIA nForce nvnet driver - CORE-15872 (low priority)
  • First test with existing closed-source driver
  • Potentially will help improving XQEMU nForce net emulation
• Improve xboxvmp driver to support NVIDIA hardware acceleration (low priority)
  • Add support for 2D acceleration
  • Add support for DirectDraw
  • Add support for Direct3D
  • Add support for OpenGL
  • Potentially will help here - CORE-16465

Backport fixes into XboxDev Cromwell

• Add ReactOS boot support based on Ge van Geldorp code
• Add ReactOS native partition boot support
• Fix array write out-of-bounds bug in rawread

Fix bugs and improve Cromwell

• Fix glitchy text characters: . _ ( f
• Fix boot device label positioning (in 720x480 and 1024x576 screen mode)
• Fix static framebuffer address (64 vs 128 MB RAM)
• Fix memory map
• 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: https://github.com/XboxDev/cromwell/issues
