Thanks for your reply, Aloone_Jonez. Here are the answers to your questions.
>Yes you do, you could run DR-DOS or even
FreeDOS, if you don't use Windows 3.1 then deltree C:\Windows.
The computer and ATE are being used under a contract with the US military, and it would take an act of Congress - almost literally - to get them to allow us to change the operating system. The computer also has four National Instruments IEEE-488 interface cards installed, and I don't want to take the time to figure out if the 488 cards or run time s/w that controls the ATE are compatible with another operating system. The options that you suggested might work, but practically speaking they aren't options.
>What version of MS-DOS are you using?
MS-DOS Version 6.00
>What specification is your machine? How old is it?
The computer has a 486 class microprocessor and was built in 1992 or 1993. The BIOS is AMI, copyright 1992.
I am starting to think that the BIOS got screwed up or the Windows 3.1 installation caused the problem. I am going to take you up on your offer to remove Windows (that should make the Microsoft haters happy), but first I want to see if I can upgrade the BIOS. I sent a request for a BIOS upgrade to an organization that represents American Megatrends Inc., and should hear back from them within two days.
Two of you folks are pretty nice for Microsoft bashers
, but the Calum can bite me. I thought that this was a Microsoft help forum when I first posted, and even if it wasn't, there's no reason to act like an idiot jerkoff just because someone asks a question. Thanks again for the help, Jonez and S kyman. Mr or Ms Calum, please stay in the UK or as far away from the US as possible. Thanks.
Best regards,
