### Installation

To install the high-resolution timer device driver, follow these steps:

1.Remove the readonly attribute from \OS2\BOOT\CLOCK*.SYS with the attrib command, e.g.:

    -r \os2\boot\clock*.sys

where * is the number in the name of your existing clock-system file.
2.Make a backup of \OS2\BOOT\CLOCK*.SYS.
3.Use DDINSTAL to install the driver.
4.Reboot.

Note: The high-resolution timer is intended for use with OS/2 Warp 3.0 and later. It has not been tested and is not supported under any previous version of OS/2. If you do use this timer with any previous version of OS/2 , you do so at your own risk.
