# 2 Windows NT

This section describes the operating system-specific parts of OTP that relate to Windows NT.

A normal installation of Windows NT 4.0, with Service Pack 4 or later, is required for an embedded Windows NT running OTP.

### 2.1 Memory Use

RAM memory of 96 MB is recommended to run OTP on Windows NT. A system with less than 64 MB of RAM is not recommended.

### 2.2 Disk Space Use

A minimum Windows NT installation with networking needs 250 MB, and an extra 130 MB for the swap file.

### 2.3 Installing an Embedded System

Normal Windows 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.

#### Hardware Watchdog

For Windows NT running on standard PCs with ISA and/or PCI bus, an extension card with a hardware watchdog can be installed.

For more information, see the heart(3) manual page in Kernel.

### 2.4 Starting Erlang

On an embedded system, the erlsrv module is to be used to install the Erlang process as a Windows system service. This service can start after Windows NT has booted.

For more information, see the erlsrv manual page in ERTS.
