When you try to start Microsoft Windows 95 you receive the following errormessage:
Not enough extended memory available to run Windows.
Quit one or more applications to increase available memory or restart your computer. Press any key to continue...
This error message can occur if you have configured your computer tocreate a RAM drive larger than 15 megabytes (MB). The error occurs even ifyour computer has enough memory to create the RAM drive and still meet thememory requirements for starting Windows 95.
A RAM drive larger than 15 MB is allocated all the available extendedmemory below physical address 16 MB. To start Windows 95 on mostcomputers, some memory below 16 MB is necessary for DMA buffers. If allthe memory below 16 MB is allocated to the RAM drive, Windows 95 cannotstart.
To correct this problem, decrease the size of the RAM drive to less than15 MB. To do so, follow these steps:
Restart your computer. When you see the "Starting Windows 95" message, press the F8 key and then choose Command Prompt Only.
At the command prompt, type
and then press ENTER.
Locate the line that contains RAMDRIVE.SYS. Change the line so that it contains a value lower than 15 MB. For example, to use an 8 MB RAM drive, change the line to read:
Save the CONFIG.SYS file and then quit the editor.
