AR# 1291: Foundation: Keylock (Sentinel driver) must be upgraded after an upgrade from Win3.1 to Win95
Foundation: Keylock (Sentinel driver) must be upgraded after an upgrade from Win3.1 to Win95
After upgrading from Windows 3.x to Windows 95, the user may lose access to the Foundation XVHDL synthesis tool.
Foundation XVHDL uses a Windows-based keylock driver. This driver is different for Windows 3.x and Windows 95.
All other Foundation and XACTstep programs use a DOS-based driver, which does not need to be changed after upgrading to Windows 95.
When upgrading from Windows 3.x to Windows 95, the following changes need to be made in order for XVHDL to properly use the keylock. These changes should be made after upgrading to Windows 95.:
1. From the Start menu, select "Run" and then type "SYSEDIT" without the quotes.
2. Select the SYSTEM.INI window and find a reference to SENTINEL.386 in the [386Enh] section. Place a semi-colon in front of the line that references the SENTINEL.386 (this will cause Windows to ignore this line). Save changes and close the window.
3. Using Windows Explorer, open the Windows\System folder and locate a sub-folder (sub-directory if you prefer the older terminology) called RNBOSENT. Delete this folder and all files within it. Note: this folder is NOT always present. Ignore this step if this is the case.
4. Close all programs and restart the computer.
5. From the Foundation CD-ROM, locate the DRIVERS folder (sub-folder of ACTIVE). Within this folder is a program called SENTW95.EXE.
6. Start the SENTW95.EXE program, select from the Function menu to Install Driver. Accept the defaults and when finished, restart the computer again.
