when the comp starts up, its in the command PROMPT and says, "this program cannot be run in DOS mode" and i dont kno what that means.. please helpWhat OS? and what program? This usually indicates you're trying to run a Windows program in DOS...unless there is more to this message.

windows 98, and it looks like this on the screen:

C:\>Set tvdumpflags=10

C:\>

This program cannot be run in DOS mode.

any ideas? ive never seen this beforeI think a program is trying to startup when he loads his computer... You need to give more INFORMATION though gsf1220...thats all it says on the screen.. its in the command prompt and thats all the information i can really give you.. is there some sort of command i can type that can tell me whats wrong with it?see bofra reply>>http://www.computing.net/security/wwwboard/forum/15681.htmlits like, the windows 98 screen comes up for like 2 seconds, then it goes black and then says that whole thing about not being able to run the program in dos mode.. but i dont recognize the program at all, and nothing else will run..hold down the f5/f8 safe mode......does it work...k, f5 makes LITTLE @ signs, f8 does nothing, and holding them down together also has no effect..you have the c:\> type scanreg/restore after it....now what happens.....do you have the win98 install disk....k, now a blue screen is up with a grey window.. it says, Microsoft Registry Checker, then in the window it has a list of dates and stuff that looks like this:

06/13/05 Started rb003.cab
06/12/05 Started rb002.cab
06/11/05 Started rb001.cab
06/10/05 Started rb000.cab

and so on down the list, then it gives the options of restore and cancel, and asks, select a cap to restore fromanybody have any ideas? merlin? you were helping a lot EARLIER.. do i just hit restore from one of the cabs?Try restore it from when it was WORKING normalpick one of those before the problem started......answer yes....when you have clicked it....>
