> This disk would be hdb in V86, have you tried booting with something mounted to hdb? I also think so, according to https://cshung.github.io/posts/xv6-on-v86/ (https://github.com/copy/v86/pull/354) and https://github.com/mit-pdos/xv6-public/blob/master/Makefile#L222, xv6 should be...

I got a lot of APIC logs from the debug log in https://copy.sh/v86/debug.html: ``` v86_all_debug.js:1 22:35:45+358 [CPU ] Not delivered: irr already set, vector=20 v86_all_debug.js:1 Previous message repeated 238 times...

Build from [andrewau/xv6-public/v86-support](https://github.com/cshung/xv6-public/tree/public/dev/andrewau/v86-support): [xv6-v86.tar.gz](https://github.com/user-attachments/files/22521337/xv6-v86.tar.gz) I used Tiny Core Linux 7.2 with gcc 5.2 to build. In v86, set 512 MB RAM and enable ACPI. Currently it stops at `assertion failed:...

Bochs with built-in BIOS works as expected: [bochsout-bochs.txt](https://github.com/user-attachments/files/22600790/bochsout-bochs.txt), [bochsrc-bochs.txt](https://github.com/user-attachments/files/22600800/bochsrc-bochs.txt) screenshot However, it doesn't work on SeaBIOS, taken from v86: [bochsout-v86.txt](https://github.com/user-attachments/files/22600971/bochsout-v86.txt), [bochsrc-v86.txt](https://github.com/user-attachments/files/22600979/bochsrc-v86.txt) screenshot ...and compiled from SeaBIOS source code: [bochsout-seabios.txt](https://github.com/user-attachments/files/22600987/bochsout-seabios.txt), [bochsrc-seabios.txt](https://github.com/user-attachments/files/22600991/bochsrc-seabios.txt),...

Interesting, I tried using `bios.bin` and `vgabios-stdvga.bin` ([default](https://gitlab.com/qemu-project/qemu/-/blob/master/hw/display/vga-pci.c#L385) in QEMU) from https://gitlab.com/qemu-project/qemu/-/tree/master/pc-bios and they don't work with `VGA_Simple_OS.iso` on v86 as expected.

Deny all restart prompts, then save the hard drive image from the emulator page and run that image again.

> As in save the state or save the image? Save the image using "Get hard disk image" button. After that, press "Exit" and re-run with a new image. 

Are you installing SoftGPU in VirtualBox or v86? If in VirtualBox, try installing it on QEMU or use "QEMU (software 3D only)" preset in SoftGPU installer.

What game/app are you trying to install? If it uses OpenGL, you can try using [Mesa3D](https://www.vogonsdrivers.com/wrappers/files/OpenGL/GDI/Mesa/)/[mesa9x](https://github.com/JHRobotics/mesa9x/releases)/[TitaniumGL (software)](http://users.atw.hu/titaniumgl/gamerdown.html). If it uses DirectX 8 - 9: SwiftShader 2.0. Anyways, have you tried...
