------------------------
## Windows NT 3.1

### Installing using QEMU

1. Install MS-DOS and [Oak CD-ROM Driver](https://www.dosdays.co.uk/topics/Software/optical_downloads.php).
2. Create 4 blank floppy disk images:

 - run `qemu-img create -f raw floppy.img 1440K`
 - mount (`-fda floppy.img`) and run `format A:` in a VM

3. Run QEMU with the following settings for installation:

```sh
qemu-system-i386 -m 64 -hda hdd.img -cpu pentium -M pc,acpi=off -cdrom InstallCD.iso
```

4. Run `xcopy /v <CD-ROM letter>:\I386\ C:\install\` in a VM to copy all files, disable the CD-ROM driver.
5. Run QEMU with the following settings: 

```sh
qemu-system-i386 -m 64 -hda hdd.img -cpu pentium -M pc,acpi=off
```

6. Run `C:\install\winnt /F /C` in a VM.
7. Follow the setup instructions. To change floppy disk, press *Ctrl+Alt+2* to switch to the QEMU Monitor, run `change floppy0 /path/to/new_floppy_image` and press *Ctrl+Alt+1* to switch to VGA.


## Windows NT 3.51

### Installing 

> [!NOTE]
> In newer versions of QEMU, the Windows Setup may not work, you can use an older version of QEMU, PCem, 86Box or PCBox instead.

1. If you install via MS-DOS, install [the Oak CD-ROM Driver](https://www.dosdays.co.uk/topics/Software/optical_downloads.php) and run `<CD-ROM letter>:\I386\WINNT /B`.
2. Follow the setup instructions.
3. After installing, download NT 3.51 SuperPack ([here](https://bearwindows.zcm.com.au/winnt351.htm#4) or [here](https://alter.org.ua/en/soft/nt_spack/nt3/)), unpack the archive into a Windows and copy files from `FAT32` (`SYS\FAT32`) and `RENEW` (`SYS\RENEW`) folders in `C:\WINNT35\system32\drivers` with replacing.

### Enabling networking

1. Open "Control Panel" > "Network", install Windows NT Networking (installation CD required).
2. In "Network Adapter Card Detection", press Continue three times, set `Network Adapter Card: Novell NE2000 Compatible Adapter`.
3. Set the following settings and click Continue:

```
IRQ Level: 10
I/O Port Address: 0x300
```

4. In "Bus Location", press OK. Check the boxes "TCP/IP Transport" and "Enable Automatic DHCP Configuration" in the next window.
5. In "TCP/IP Configuration", check the box "Enable Automatic DHCP Configuration".
6. Restart the VM.


## Windows NT 4.0

Recommended version: Windows NT 4.0 SP1

### Installing using QEMU

1. Run QEMU with the following settings for installation: 

```sh
qemu-system-i386 -m 64 -hda hdd.img -cdrom InstallCD.iso -cpu pentium -M pc,acpi=off
```

2. On setup startup, press F5 and select "Standard PC".
3. Follow the setup instructions.

### Running in v86

Due to a problem with CPUID, you need to add `cpuid_level: 2` and `acpi: false` to the V86 constructor (not supported in the UI):

```js
var emulator = new V86({
    ...
    cpuid_level: 2,
    acpi: false
});
```


## Windows 2000/XP

### Installing using QEMU

1. Run QEMU with the following settings for installation: 

```sh
qemu-system-i386 -m 512 -hda hdd.img -cdrom InstallCD.iso
```

Optional:
 - add `-device sb16` to enable sound
 - add `-nic user,model=ne2k_pci` or `-device ne2k_pci,netdev=<...>` to enable networking

2. Follow the setup instructions.
3. This step fixes the error `Uncaught RangeError: Maximum call stack size exceeded` in Chromium during Windows 2000/XP startup in v86.

After installation, change the computer type to "Standard PC" as described [here](http://web.archive.org/web/20220528021535/https://www.scm-pc-card.de/file/manual/FAQ/acpi_uninstallation_windows_xp_english.pdf):
1. Open Start menu, right-click on "My Computer", select "Manage"
2. Open Device Manager, open Computer, right-click on "ACPI Uniprocessor PC"
3. Select "Update Driver..." > "No, not this time"
4. Select "Install from a list or specific location (Advanced)" > Next > "Don't search. I will choose the driver to install." 
5. Choose "Standard PC", press Next > Finish.
6. Restart the VM, follow multiple "Found New Hardware Wizard" dialogs with default options.

### Enabling True Color (for Windows 2000)

> [!NOTE]
