My recmommendation: Set the clock to 40mhz. Install a 486DX4 chip. But, (and this the important part),..... install a cooling fan directly on the that 486DX4 chip. ****** Without a cooling fan on the chip itself. ******* ****** You'll burn it up in a matter of minutes. ******* You'll end-up with (almost) the "Icomp" performance of a Pentium 75mhz http://www.angelfire.com/id/glenndoom/icomp.htm Glenn McCorkle [EMAIL PROTECTED] North Jackson, Ohio, USA DOS prog. for QV cameras http://www.angelfire.com/id/glenndoom/qvplay.html Other stuff http:[EMAIL PROTECTED]/ -- Arachne, The Web Browser for DOS Open the 'DOOR' to the WWW.
