2 Windows NT
This chapter describes the OS specific parts of OTP which relate to Windows NT.
A normal installation of NT 4.0, with service pack 4 or later, is required for an embedded Windows NT running OTP.
RAM memory of 96 MBytes is recommended to run OTP on NT. A system with less than 64 Mbytes of RAM is not recommended.
A minimum NT installation with networking needs 250 MB, and an additional 130 MB for the swap file.
Normal NT installation is performed. No additional application
programs are needed, such as Internet explorer or web server. Networking
with TCP/IP is required.
Service pack 4 or later must be installed.
For Windows NT running on standard PCs with ISA and/or PCI bus there is a possibility to install an extension card with a hardware watchdog.

On an embedded system, the erlsrv module should be used, to install the erlang process as a Windows system service. This service can start after NT has booted. See documentation for erlsrv.
