【PCエミュ】bochs Part2【フリー】

結局の所速度はVirtualBOXやQemuに負けるのは
やむ終えないからそちらを使えばよい。
最近は速度UPを進めてるが直ぐにはいかないよね。
一応2.3.7やCVSは早くなりつつあるようですけどね。

>>715
実はCVS版でWindows95動いてたりする。
Windows3.1は前から動いていた様ですが。
0.72のリリースが07年8月。
いつになったら新版出すんでしょうね。

>>719
つーことはDOSBOX上でQEMUが動くってことか？

>>728
動くかどうかは分かりませんが必要性あるかな。
DOS上でQemuが動くってニュースはどこかにありましたが

HX DOS EXTENDERの話題が出てたので、試しにDOS上でBochsを起動してみた
そしたらDOS上のBochsであっさりWindows95が起動した。なんか楽しいｗ

>>730の追記
MS-DOS7.10 + HX DOS EXTENDER + Bochs で Win95が起動したけど
画面設定を16ビットにすると画面全体が水色っぽい色になる。8ビットと24ビットは正常
あと、キーボードが効かなくなったりと不完全な部分があるね
体感速度は同じような感じ。実用性はあんまりない

>>725
今試してみたが、同じイメージは使えないぞ？

http://www.surprise002.co.nr
すごく安くて助かってます
拝見する価値はあると思いますよ

>>732
標準(flat)のHDイメージならBochs、Qemu、DOSBOXどれでも使えるはず

ただしDOSBOXの場合は、HDイメージのサイズが500MB以下じゃないと
認識しなかった気がする

Windows build is available. (No debugger-enabled build provided)
1. New CVS source was used.
2. ZIP/7Z mount was removed due to less maintenance of physfs patch.
3. Pressing Alt-pause does not show a configuration window any more.
4. Fixed some minor bugs.

が該当のスレッドらしいが・・・

DOSBOXの話題でなんだけど、起動時に赤いブート画面が表示されるようになったのね
違うもんを起動したかと思って、びっくりしたわ

iPhoneでwin95動くらしいな。

>>744
iPhoneでもBochs動いたんだね。
Bochsって本当に移植性高いね。
でもiPhoneってARMの600MHzだろ？
もっさりで非実用的。

>>745
動くだけって感じ。
よくしらないんだけどbochsでwin95以外のOSをiPhoneではしらせることってできるの？

やってみた方が早いんじゃないか？お手本ハードに対応してりゃ動くだろ。
っていうか最近なにか面白いOSある？

>>700-706
そんなに責めることですか

そんなに遅レスることですか？

懐かしいスレだな。

Changes in 2.4.2 (November 10, 2009):

- CPU and internal debugger
- VMX: Implemented TPR shadow VMEXIT
- Bugfixes for CPU emulation correctness (mostly for VMX support).
- Bugfixes and updates for Bochs internal debugger
- On SMP system stepN command now affects only current processor

- Memory
- Bugfixes for > 32-bit physical address space.
- Allow to emulate more physical memory than host actually could or would
like to allocate. For more details look for new .bochsrc 'memory' option.

- Cleanup configure options
- All paging related options now will be automatically determined according
to --enable-cpu-level option. Related configure options
--enable-global-pages, --enable-large-pages,

- Deprecate --enable-daz configure option. Denormals-are-zeros MXCSR control
will be enabled automatically iff SSE2 is supported (like in hardware).
- Deprecate --enable-vme configure option, now it will be supported iff
CPU_LEVEL >= 5 (like in hardware).

- I/O Devices
- Bugfixes for 8254 PIT, VGA, Cirrus-Logic SVGA, USB UCHI

初歩的な質問でもうしわけないが
cirrusドライバ使って高解像度仕様にしたんですが
色数が16色のまま変更できません。
モニタかなにかでしょうか

環境は
WindowsＸＰ上のBochs2.4.2で
ＯＳはWin95初代、　VGAドライバは
Cirrus5446の日立のアレのドライバです
よろしくお願いいたします

bochs Android版ってどこにあんの

Changes in 2.6.2 (May 26, 2013):

- CPU

- VMX: fixed write of guest segment access rights VMCS fields (32-bit field
was truncated to 16-bit)

- CPUID: Enable all supported VMX capabilities for bx_generic CPUID configuration.
- CPUID: Enable X2APIC support for Ivy Bridge CPUDB configuration.

compiled with CPU_LEVEL > 5.

- Misc
- Fixes for Bochs port on MorphOS (based on a patch by Thore Sittly):
missing functions, byte-swapping and cdrom support.

久々のアップデート

Changes in 2.6.5 (June 1, 2014):

- CPU: extra 5-10% emulation speedup with new trace linking optimization
- CPU: implemented new instructions (e.g. AVX-512, SHA, XSAVEC)
- CPUDB: added 2 new CPU models
- Bugfixes for CPU emulation correctness (including some critical ones)
- Gui debugger output window now can be used as a log viewer
- Added built-in slirp (user-mode networking) support (ported from Qemu)
- Added global sound config option and volume control support to the devices
- Added new experimental gui 'vncsrv" using the LibVNCServer library
- Rewrite of the bximage utility in C++ for image creation, conversion and resize

バグフィックスリリース

Changes in 2.6.6 (June 15, 2014):

- CPU / CPUDB
- allow sandy bridge configuration even when AVX is not compiled in

- Configure and compile
- fixed compilation error when 3dnow support is enabled
- speedup Visual Studio build by almost 20% by adding /Gr compiler option

- Misc
- fixed minimizing win32 gui window and resolution change while minimized
- added compiled SeaBIOS 1.7.5 image into Bochs tree along with Bochs BIOS images
- documentation fixes and updates

Changes in 2.6.7 (November 2, 2014):

- CPU / CPUDB
- Implemented AVX-512BW/AVX-512DQ/AVX-512VL extensions emulation.
- implemented AVX512-IFMA532 instructions emulation.
- implemented AVX512-VBMI instructions emulation.

- Fixed Bochs segmentation fault crash with Handlers Chaining Speedups enabled when
compiling with gcc, especially with low optimization levels.
- Reverted removal of reporting Architectural Perfmon support in pre-defined CPUID modules.
Windows 8 and Windows 10 require Performance Monitoring to be reported to boot.
To workaround possible Windows 7 64-bit installation issues: use bx_generic CPUID module,
which doesn't report Performance Monitoring in CPUID.

- GUI and display libraries
- The VGA update timer and the status LED timer now always use the realtime mode
independent from the 'clock' option setting.
- Added native SDL2 GUI support to Bochs. To enable configure with --with-sdl2.

- I/O Devices
- USB
- xHCI model now emulates a NEC/Renesas uPD720202 device (patch by Ben Lunt).
- Added USB port specific option 'size' for VVFAT disks (range 128M ... 128G).
If the size is not specified or invalid, it defaults to 504M.
- Hard drive / HD image
- Fixed crash when using a "fixed" type VPC image.

- ROM BIOS
- Fixed int74_function() for 4-byte (wheel mouse) packets.

- LGPL'd VGABIOS updated from CVS (fixed building VBE modes list)

- Misc
- Visual Studio workspace files updated to VS2013Ex format.
- bximage_old/bxcommit: removed old obsolete image manipulation tools.
- Documentation fixes and updates.

ここ最近リリースされたOSで動くのってどの辺？

Hi all!

When releasing Bochs 2.6.7 I did not check whether or not the new
release runs on Windows XP. Some weeks after the release we have been
informed that it doesn't work on this legacy, but still popular OS.
I have now added a ZIP package to the 2.6.7 release folder that contains
XP-aware binaries. Note that it is based on the 2.6.7 sources and
doesn't contain any bugfixes or new features present in SVN.

We are planning a new "bugfix+" release for the end of March. It will be
built from SVN and contain all our work of the last months. Of course,
the default win32 package should run on XP again.
