If Windows 3.X Fails to Load

Here are some things to check if Windows 3.X fails to load when Invisible LAN is running:

1. THE DOS PORTION of Invisible LAN must load and function properly at the DOS prompt before attempting to start Windows.

2. NETWORK CARD IRQ must not conflict with other devices that actuate when Windows loads (COM ports, modems, sound cards, etc.). Note that Windows always actuates all COM port IRQs, even if there is nothing connected to the port.

3. WINDOWS SUPPORT = Y
(Check SETUP30, Advanced Configuration, General Network Parameters, and make sure "Windows Support" is set to "Y").

4. CACHE DATA SIZE (if using Invisible LAN disk cache) must be not be 0.
If the cache size is 0, the cache uses all memory, leaving nothing for Windows. Also, the Cache Data location must be XMS or EMS.
(Check this in SETUP30, Advanced Configuration, Disk Cache Parameters)

5. PRIVATE FILES = N
The server's "private files" setting must be "N", otherwise Windows won't run. Also, confirm that server files do not exceed 200. (Maximum server files on Windows machine is 200.)
(Check this in SETUP30, Advanced Configuration, Server Parameters)

6. NO DRIVES ARE SELF - MAPPED (loopback)
Some computers do not accept self-mapping to generate drive letters. Use the SUBST command in the AUTOEXEC.BAT file instead (type HELP SUBST from DOS prompt for assistance).

7. INVISIBLE LAN WINDOWS DRIVERS ARE LOADED
Make sure that the Invisible LAN Windows drivers are loaded. From Program Manager, double-click on Windows Setup, and check that Invisible LAN is installed as the network.

If none of these fix the problem try inverting your Windows swap file (from temporary to permanent or vice versa.)
