Windows NT 3.1 issue in virtualbox

[Techanch]

Whenever I try to install Windows NT 3.1 in Virtualbox 5.0, but when I get to the GUI part of the install, I get a error saying that your CPU is not supported, I have a Dual Core Pentium E5700 @ 3Ghz, heres my system info if it helps:

OS: Windows 10 Pro
CPU: Pentium E5700 Dual Core 64bit 3GHZ
RAM: 6GB DDR3

Windows NT 3.1 only supports certain types of CPUs. After doing the text based setup (boot from floppy and copy base OS files), you should boot from a DOS floppy & run the edit program.
Open the file Initial.inf located in %WinDir% (where your Windows install is) \System32.
Change the line: "STF_PROCESSOR = $(LIBHANDLE) GetProcessor" to "STF_PROCESSOR = $(ProcessorID_I586)" under "[ProcessorVar]". Do the same for SETUP.INF and it should work.
Don't forget to save the files before exiting the edit program.

The sound drivers are not installed by default. If you want sound to work properly, pick Creative Sound Blaster 1.5 or something like that.
