Activity for Bochs x86 PC emulator
-
Stanislav Shwartsman modified ticket #360
New instrumentation call for DMA transfers
-
Implemented in git
-
[PATCH] rewrite eth_fbsd.cc (using netgraph)
-
obsolete, if you have updated one - please submit in github
-
Display Host/Guest mode on GUI debugger
-
Implemented different way now
-
Save and restore window positions
-
Rejecting, nobody asked this single 2009. If still required - open github ticket
-
What the report says, against current code PCI interrupts do still reach two I/O APIC inputs: pci_set_irq() drives input 16 + pirq (pci2isa.cc:224). The routed ISA IRQ then goes through DEV_pic_set_irq_level(). raise_irq() and lower_irq() forward it to I/O APIC input X (pic.cc:498, pic.cc:474). The recent fixes didn’t change this dual routing. They are 79b10b2b9 (Remote IRR, moving asserted PIRQ lines when the routing changes), 862acecfa (a level-triggered entry whose line is already high is pending)...
-
Sending EOI to Local APIC acts that all interrupts is complete
-
Fixed by 4e4a0f309 and 79b10b2b9 / 1cd5b8d5e
-
emulate MacOSX in Bochs
-
duplicate
-
ACPI table additions to satisfy Mac OS X
-
Superseded: processor objects (legacy BIOS SSDT and UEFI tables, 40b0ed066), Apple SMC ACPI device (392cb8186), and HPET/RTC are in the current DSDT. The remaining parts copy machine-specific Mac firmware data and don’t apply to Bochs
-
Snapshot on magic CPUID
-
there is CPUID instrumentation call, in instrumentation module you can do whatever you want, including snapshots
-
bochs debugger gui do not switches to 'magic breaked' CPU
-
Fixed in master
-
MACRO of USER_CS has a wrong value
-
Fixed in master
-
add ability to turn on instruction trace
-
Enabled with ability to turn on debugger on demand
-
Give us a small gui to configure / .bochsrc
-
Bochs supplies small GUI for building .bochsrc configure is run so rarely that it should not require any separate GUI
-
let bochs sleep when the simulation is idle
-
Seems like most of the request is already implemented If you want to escalate what is left - please open github issue, this issue tracking is deprecated
-
Second window and copy option for debugger
-
Second window and copy option for debugger
-
closed as duplicate if want to escalate - please reopen as github issue
-
fixed bochs info tab for 64 bit FAST.
-
fixed bochs info tab for 64 bit FAST.
-
already implemented
-
Adjustable sleep rate for emulator slowdown
-
Already implemented with slowdown timer
-
verbose information about hardware states and processes
-
EFI, TPM...
-
EFI is supported, TPM support present in another request on github

I’ve been experimenting with Bochs and I’m interested in using it for older Windows games and software. One thing I like about emulation is being able to recreate an older environment instead of trying to make every legacy application work directly on a modern operating system. For anyone who has experience with Bochs, how to run old Windows games with Bochs on a modern PC reliably? Are there particular CPU, VGA, memory, or BIOS settings that you normally recommend for better compatibility? I’m especially...

Hi everyone, I've been reading about how BIOS firmware interacts with emulators, and one thing that seems easy to overlook is that a BIOS image is not always interchangeable between different systems. The emulator has to reproduce enough of the expected hardware environment for the firmware to initialize correctly. This also comes up when comparing different console emulators, where BIOS versions and regions can affect compatibility and startup behavior. I found [this BIOS and emulation resource]...

Interesting discussion, especially the later point about BIOS compatibility depending on the hardware Bochs is emulating. It’s a good reminder that a BIOS image isn’t just generic boot code — it can expect particular chipsets, peripherals, memory layouts, and firmware behavior. For anyone researching BIOS images and how they relate to emulation, I’ve also been collecting some background material . The site focuses mainly on PlayStation BIOS and emulation rather than Bochs, so it’s more of a general...

Lack of repeatability
-
Debugged memtest failure last week - was perfectly repeatable, even up to level that failure happened always on the same time tick on every run
-
Support for (U)EFI
-
support for UEFI was finally added
-
The limitations of the RFB gui are documented. It doesn't support connections with > 8 bpp color depth, but your VNC viewer requests 24 bpp. Please set up your VNC viewer to use the formats RGB332 or BGR233. If you need support for > 8 bpp, or you'd like to use Bochs in a web browser you should try with the 'vncsrv' gui that requires the libvncserver library. You should visit the Bochs page on GitHub to follow the development.

Oliver created ticket #513
Could you add Hercules text and optional graphics mode support?
-
Jorge Vidal Wulff posted a comment on a wiki page
beware, that so called "software bug report" is malware
-
AGP or PCI Express support
-
AGP is WIP, For PCI-Express where is another request open in github. Closing this as duplicate
-
Add "Run To Cursor" command to debug
-
New 'rla' command was added to debugger exact to do that mentioned Run to linear address. GUI debugger support (another feature request) is next step
-
Bochs should use the OSX toolbar
-
Seems like outdate, if the request still relevant - please reopen on github
-
compressed harddisc image format
-
new FreeDOS BOchs image
-
Already become obsolete
-
Utilities to mount bochs images as hard disks
-
Not a Bochs request, tools like WinImage already able to manipulate disk images from Bochs
-
VPN client
-
Should be already possible. Not a Bochs request.

Raven Black modified a comment on ticket #512
I haven't tried compiling Bochs I will admit that. Would rather just use the product. I use wsl2 on windows and the wsl terminal to compile my os but I use Bochs and when I choose Bochs debugger to run the os or floppy, it will not let me copy the information from the Bochs debugger. You run the os on that Bochs screen right? That Bochs screen is representing a monitor. When making an os I think it would be fun to test having a second monitor or Bochs screen so you can move apps around from screen...

PocketPC support
-
Windows CE is dead and obsolete

Ok, thanks, at least you know what I am talking about now lmao!!

Request for 2nd monitor (2nd emulated montitor) already present even here. Multi-Head support: https://sourceforge.net/p/bochs/feature-requests/15/ It is probably hard to do so nobody tries. If you want to highlight it more - better to open another request on github. But one request for one feature.
