Hello: I have a Pentium PC with an issue with a few games stating not enough memory. If I take out the CD ROM lines in the Autoexec.bat and Config.sys files, the game loads fine; however, I cannot manually initialize the CD ROM without the line in the Config.sys file. When I put the line in (DEVICEHIGH=C:\DOS\OAKCDROM.SYS /D:MSCD001) it auto loads the cd rom driver, and the games do not work. In Upper Memory, I have CTMOUSE, and SETVER. I have 52,400 free in Upper Memory. Can I load the CDROM, and/or SmartDrv in upper memory? If I replace DEVICEHIGH, with LH it states error in line 3 on config.sys (line 3 is the CD ROM). Or just disable Smartdrv? If so, how?
