Windows NT 3.1 build 239 is the December 1991 build of Windows NT 3.1. Like in earlier builds, Sound Blaster configuration is hardcoded for I/O port 0x260 and IRQ 7.
New features and changes[edit | edit source]
The color palette has been changed back to a more vivid one used by Windows 3.1 and build 196 as opposed to the older Windows 3.0 palette used by the October build.
The Video 7 VGA driver now also supports 1024x768 at 16 colors as opposed to only 800x600.
MIPS compile[edit | edit source]
This is the earliest available build of NT for the MIPS architecture. Due to its earliness a custom ARC firmware ROM image must be used otherwise the installer and boot loader will crash or exit. The build will boot in QEMU but due to requiring G300 graphics (G364 is what is emulated) will not show any UI. In MAME the build can install successfully (despite emulating the "wrong" graphics card) but the boot entry is incomplete and needs to be fixed in ARC firmware setup after installation.
