For many years I use a sound card Yamaha OPL YMF 719-S in one PC Pentium 133 MHz - 32 Mb RAM with DOS 6.00 / Windows 3.1 and Yamaha`s drivers. But upon wanting to use that card with Windows For Workgroups 3.11 on the same computer, WFWG can not be begun normally with the net drivers, since present the following fail message: "Not enough extended memory available to run Windows. Quit one or more applications to increase available memory or restart your computer" I already I proven with the programs SYSHOOK.DRV, MOREMEM 4.0, FIX1MB, and 1MBFORT 1.0 to see if could improve something, but I could not solve the problem. Furthermore, when I make to run WFWG without the net controllers (WIN /N), Windows run perfectly and permits to reproduce music. On the other hand, when I install a Sound Blaster 16 card with their drivers on the same PC, no have that problem. Help me, please... Daniel G. Gionco Buenos Aires - Argentina

Are the drivers you installed correct I Have a Twinhead notebook with a yamaha sound card running 3.1 it works fine The notebook speed is a 233 MHz with 32 meg ram Get the 3.1 drivers for your system Try this site http://www.yamaha.co.jp/english/product/lsi/us/support/downloads.html and let there be music

This usually happens if a bad or incompatible file gets loaded in the system.ini-it's not actually a memory problem per se ..in dos, using edit text editor, check your 'device' category in system.ini and remark out , one by one, any non-essential (or newer) devices (exe files) until you find the culprit..it could even be corrupt or incompatible net drivers...

Thanks "EM386N" and "Dominicus"... After a short investigation, I discovered that how Dominicus says, there are a incompatible file gets loaded in the system.ini`s section [386Enh]: vsgm.386 (1333879 bytes). But, these device is essential for the sound card Yamaha OPL YMF 719-S in Windows. If someone can add some other idea to solve this problem, please help me... Daniel G. Gionco Buenos Aires - Argentina
