2183E Windows NT Device Driver Installation

If installing with a CDROM Drive.

1. It is necessary that the CDROM drive be situated as a slave on the primary port, since the built-in ATAPI.SYS will NOT recognize the secondary port.
2. Once installation is complete, rename the built-in ATAPI.SYS driver to ATAPI.ORG. Then copy the DTC ATAPI.SYS driver in place of the built-in ATAPI.SYS.
   • C:\WINNT35\SYSTEM32\DRIVERS> REN ATAPI.SYS ATAPI.ORG
   • C:\WINNT35\SYSTEM32\DRIVERS> COPY A:\ATAPI.SYS

   NOTE: CDROM driver (provided by drive manufacturer) must ATAPI 1.2 compliant.

3. Reboot
4. The CDROM can now be reconfigured to the secondary port if so desired.

If installing w/o a CDROM Drive.

1. Once installation is complete, rename the built-in ATDISK.SYS driver to ATDISK.ORG. Then copy the DTC ATDISK.SYS driver in place of the built-in ATDISK.SYS.
   • C:\WINNT35\SYSTEM32\DRIVERS> REN ATDISK.SYS ATDISK.ORG
   • C:\WINNT35\SYSTEM32\DRIVERS> COPY A:\ATDISK.SYS
2. Reboot

NOTE: If installing Windows NT with a CDROM Drive attached, Windows NT will automatically load the built-in ATAPI.SYS driver, and NOT the built-in ATDISK.SYS driver. Only ONE driver can be enabled.
