Most glide games are win 98 and win 98 doesnt support more than 775 megs of RAM i think.. Heres a link
http://support.microsoft.com/kb/253912If a computer that is running any of the versions of Windows that are listed above contains more than 512 megabytes (for example, 768 megabytes) of physical memory (RAM), you may experience one or more of the following symptoms:
You may be unable to open an MS-DOS session (or command prompt) while Windows is running. Attempts to do so may generate the following error message:
There is not enough memory available to run this program.
Quit one or more programs, and then try again.
The computer may stop responding (hang) while Windows is starting, or halt and display the following error message:
Insufficient memory to initialize windows. Quit one or more memory-resident programs or remove unnecessary utilities from your Config.sys and Autoexec.bat files, and restart your computer.
So if in win XP or an NT OS, You may have to use third party Drivers.
