You did not say if you are using your computer for older DOS programs, if you do please post more information. If not, start SYSEDIT.EXE and change your Config.sys: Delete everything except the line about Himem.sys or put REM before everything you donīt need, and in Autoexec.bat, remove everything or comment them out with REM and leave this line: SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND This will give you a clean start-up boot. Another example, here are my start up files from my Win98SE machine, they include a generic CD driver in Config.sys and sound card setup. Config.sys: DOS=HIGH,UMB DEVICE=C:\WINDOWS\HIMEM.SYS /TESTMEM:ON /V FCBSHIGH=1 LASTDRIVEHIGH=Z DEVICEHIGH /L:2,3712 =C:\WINDOWS\IFSHLP.SYS /V DEVICEHIGH /L:2,40800 =C:\WINDOWS\OAKCDROM.SYS /D:MSCD001 /V Autoexec.bat: SET BLASTER=A220 I5 D1 H5 P330 E620 T6 SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND SET TEMP=C:\TEMP SET TMP=C:\TEMP Howard Rubin in Fortaleza, Brazil Original post: Date: Tue, 30 Jul 2002 13:00:05 -0500 From: Ryan Shibuya <[log in to unmask]> Subject: ERROR: "XMS Driver Not Installed" OS: Windows95.
