    I am trying to reformat my hard drive so I can install Windows 98.I have a Thinkpad 390e,and the dos command:
    "C:\reformat" does not work
    Is there another series of commands to use to reformat?

    Are you trying to format your laptop and reinstall windows and you have a choice of a floppy disk or cdrom, but not both at the same time? It's tricky. I just did it and it wasn't easy. Here's the way I finally did it:

    l. On my desktop pc made what I call a "Format disk" containing fdisk.exe, format.com, and command.com. Used this to boot the laptop, run "fdisk", then "format c:/s". (I found that not every version of format will support the /s switch). I was then able to boot the laptop from its own hd and it would recognize both the a: and c: drives. This is an important first step.

    2. I located on my desktop pc and added to my "format disk" the following files:

    OAKCDROM.SYS (your cdrom drive may need a different driver)
    EDIT.COM (because I wound up making changes to the following to get them to work)

    Then use Notepad to create an AUTOEXEC.BAT file containing the following line:

    MSCDEX/D:MSCD001 (those are zeroes)

    and a "CONFIG.SYS" file with the following lines:


    (For me this second line worked with no spaces. Most sources I have seen show a space after sys) (your cdrom may need a different driver) Make sure that the D:MSCD001 appear exactly the same in autoexec.bat and config.sys.

    3. Copy these files from the a: to the c: directory of the laptop. Power down, remove the floppy drive, install the cdrom drive. On power up the cdrom drive will be recognized as drive d if you do all the above correctly. Then just insert your windows cd in drive d, and change to the d: prompt, then type "setup". That's all there is to it. Just be aware that your cdrom drive may need a different DOS driver. Your laptop would be the best source of the correct driver. Also, go to google and search for "MSCD001" for more info.

    Good luck. Let us know how it turns out.
