Problem
Solutions: Troubleshooting Setup Running Enhanced Mode Make sure the customer has the following: * 1024K of extended memory * HIMEM.SYS is loaded first * EMM is not taking all the extended memory * 384K or conventional is free If all items listed above look okay, it could be a hardware conflict of some kind. When Windows starts in 386 Enhanced mode, it goes out and examines the Upper Memory Block (384K reserved address area) to see if there is any free memory where it can place the translation buffers. If it finds a free area, Windows installs the buffers. The problem arises when not all of the adapters that use this area "sign in" as being there. If your system crashes (abnormal termination of program execution) and/or locks when going into 386 Enhanced mode, the customer needs to insert EMMEXCLUDE=A000-EFFF into the SYSTEM.INI file under the [386ENH] section. If a user can get to the logo screen and then the screen goes blank, they probably have a display adapter problem. Windows does not support extended modes (800x600 or 1280x1024). See if they can run the card in the normal 640x480 mode or contact their manufacturer. |
