MS DOS

By stillwaitin4th1 ·
I have a very old computer that was just given to me. I was trying to find solitaire or someother game and opened ms dos instead. I wrote something in the command area and closed it. Now everytime i turn on and off the computer it will go to a different screen asking the for the right command to override safe mode (because my computer turns on to safe mode). The only way I am able to by pass this screen is to press F5 and it will take me to the general computer items but it will not allow me to play cd's or any other type of audio. What should I do?

The easiest way around the problem is to wipe the HDD and reload DOS and any other programs that you had installed.

From memory there was no Safe Mode in DOS it either worked or didn't you didn't have the option to open it with a limited set of Drivers as MS DOS was the most basic one available at the time.

The only time I ever saw MS DOS was on new computers where I immediately wiped the drive and reloaded with DR DOS as it was much better and you had far more flexibility with it.

But there are a couple of things to check first if this is a really OLD M'Board they had a Electrolytic Capacitor on the M'Board instead of a Battery if this is the case replace it now before it leaks and destroys the M'Board you'll be able to pick up a replacement Capacitor for a few dollars at Radio Shack and cheaper if you go to one of the electronic Wholesalers.

As fas as reloading goes you'll only need about 15 - 20 Floppies and you'll have everything necessary to run the computer with.. Some of the old Computers didn't have On Board IO Controllers so you had to plug in a separate ISA or Vesia IO Card and many had CD Roms driven off the Sound Cards so to get them working you had to first install DOS then the sound Driver and then the CD ROM Driver. These are not ATAPTI drives and can not be treated as such.

this is a wonderful answer but i'm not the best computer literate person so a lot of this is confusing. i have written another question that would help this answer a bit more. all i do is turn on the computer and it says its going to do a memory check and it goes to that screen. i want to override this but i don' know how... please help...

Hi-
Hal is correct, there is no safe mode in DOS, there also is no F5 option, I suspect it was originally running something like win95?
We need to know what OS it was running, if it was win 95/98 you may be able to fix it by letting it boot to safe mode, click run, then typing msconfig in the box, once there make sure the "normal startup" button is checked, it may have a slightly different name depending on the version of windows installed.

Add a note to your post, let it boot into "safe mode" and tell us what its running.
E.D.

Call Geek Squad or have a compotent technical person repair the issue. Then go to the library and get a book on How Computers Work and start studying.

The Memory Test can not be overridden as it is part of the PRE DOS Power On Self Test of commonly known as POST for short.

At this stage you are running on the CMOS stored data in the BIOS chip and there is nothing of the computer actually working just the preparation to start things off and let the computer know what is attached in the form of Memory, HDD and any floppies. What type and how big and where they are situated so that the system can start up and run.

While it is technically possible to prevent the RAM Check to do so you would have to disable the BIOS Start up and hence the complete computer as it needs to test these things to enable it to work. Here it doesn't matter if it's an old 286 or the latest Pentium Extreme they all have the same process working although with the newer ones the RAM isn't checked at the KB level as the RAM loads are now generally much bigger than the Old DOS days where a 1 MEG system was considered as big.

you can skip the memory check [which on your screen looks like a count up to the total memory in the system] by changing the BIOS. The BIOS will check for memory present, just not do the count up looking for bad areas in memory.

when you boot up, what do you see after the BIOS loads? a C:> prompt? an A:> ?

mem is the DOS command to show your system memory and whats allocated where.

The config.sys file is used to configure the system. you can use the =UMB command or load high command to load programs into upper memory blocks[the area above 640k]. Some versions of MS DOS have Smart Drive and Ram Drive [which as also configured in the config.sys file].

Biggest question is what operating system are you really using?

Actually you CAN skip the memory test by pressing the escape key when the memeory is being tested. But you must let us know what verion of windows that is running, your system will not play sounds or run the CD in safe mode in either Windows 95 or 98. There was no dos mode in Windows 3.1

after the memory check and before windows starts, repeatedly press the "F8" key, this will give you a Dos menu, select command prompt only.
then type ver and press the enter key.
then tell us what VERsion the system reports.
"after this, try typing win and pressing enter, to see if the system boots normally.
