DOS ain't dead

The Bochs Project released version 2.7 on 01 August 2021.

Summary of changes since version 2.6.11:
- Bugfixes for CPU emulation correctness (CPUID/VMX/SVM fixes to support
  Windows Hyper-V as guest in Bochs)
- Improvements for the plugin handling to simplify Bochs extensions
- Added "multiple NICs" support to the NE2000 and E1000 devices
- Added experimental FTP service for networking modules 'vnet' and 'socket'
- Fixes and improvements for all supported Voodoo graphics adapters
- Added USB keyboard emulation with most of the keys supported
- GUI "cmdmode": create a headerbar event with key combo starting with F7
- LGPL'd VGABIOS updated to version 0.8a (new VGABIOS for Voodoo Banshee)

Most important change for me: No more official 32-bit binaries! -- See replies for my progress on rolling my own Windows XP x86 binaries. See https://www.bttr-software.de/download/bochs/ for my binaries.

Also note: You need to change, e.g., "pci: enabled=1, chipset=i440fx, slot1=pcivga, slot2=ne2k" to "pci: enabled=1, chipset=i440fx, slot1=pcivga, slot2=ne2k0" in your Bochs configuration files, because of the "multiple NICs" support added.

I'm taking the long road with my limited C/C++ knowledge and ancient MinGW/MSYS toolset. I guess, it would be easier with Visual Studio (Express) <= 2017, but where is the fun then?

First result is available from: https://www.bttr-software.de/download/bochs/

Meanwhile I made a small change only: I added 'Comments' to the StringFileInfo block to clearly say, that it's me to blame for this build.

I also uploaded my patches, a build script, and some building instructions. (No rocket science in it.)

Another update: By switching from MinGW32 v3.1 to v3.4.2 I could enable support for guest memory larger than the host supports via compile-time option '--enable-large-ramfile'). -- This is untested!

Today's release now includes 'bochsdbg.exe'.

Thanks, I quickly tested in my XP-SP3 and works like previous official version.

Thanks for your feedback!

Meanwhile I did some fine tuning to my docs. Among that, I also provide a registry file now to register the BXRC file extension with Bochs: https://www.bttr-software.de/download/bochs/

It's even possible to register more than one Bochs version.

Export from my system:

REGEDIT4

### Version 2.6.11 ###

[HKEY_CLASSES_ROOT\BochsConfigFile\shell\Configure_2611]
@="Konfigurieren mit Version 2.6.11"

[HKEY_CLASSES_ROOT\BochsConfigFile\shell\Configure_2611\command]
@="cmd.exe /c \"set BXSHARE=D:\\Emulators\\Bochs-2.6.11&&D:\\Emulators\\Bochs-2.6.11\\bochs.exe -f \"%1\"\""

[HKEY_CLASSES_ROOT\BochsConfigFile\shell\Debugger_2611]

[HKEY_CLASSES_ROOT\BochsConfigFile\shell\Debugger_2611\command]

[HKEY_CLASSES_ROOT\BochsConfigFile\shell\Run_2611]
