2.You may have entered an incorrect hard disk drive type when you ran the Setup program to configure your hard disk. See Chapter 2 for information and check the hard disk drive type table in that chapter for a list of the types available. If you entered user-defined parameters to configure your hard disk, check the information that came with your hard disk to ensure that you use the correct parameters.

3.If you have installed MS-DOS on the hard disk but it does not load MS-DOS when you turn on the computer, it may be missing one of the MS-DOS system files. Turn off your computer and insert your Startup diskette into drive A.

Then turn on your computer again.

Type C : and press Enter to log onto the hard disk. If this works, the next step is to make sure the file COMMAND.COM is in the root directory of the hard disk. Type DIR and press Enter.

If COMMAND.COM is in the root directory, use the MS-DOS COMPARE command to compare the COMMAND.COM file on your diskette with the COMMAND.COM file on the hard disk. (See your MS-DOS Reference Manual for instructions on using COMPARE.) If the files do not match, use the COPY command to replace COMMAND.COM on the hard disk with the COMMAND.COM file on your diskette. Type the following and press Enter:

COPY A:COMMAND.COM C:

4.If the hard disk still does not work, the root directory of your hard disk may be missing some hidden system files. (Hidden files are not displayed when you list files using the DIR command.)
