IBMDOS.COM
 | It has been suggested that this article be merged into IBM PC DOS. (Discuss) Proposed since January 2012. |
IBMDOS.COM is the filename of the DOS kernel.
It exists in PC DOS 1.0 to 7.10 and DR-DOS 5.0 and higher (except for DR-DOS 7.06), with MS-DOS using MSDOS.SYS (from version 1.0 to 6.22) for the same purpose. DR DOS 3.31 to 3.41 used DRBDOS.SYS instead.
The file is located in the root directory of the drive containing the operating system and gets loaded by the IBMBIO.COM file in the boot process.
By default, the file is located in the root directory of the bootable drive/partition (normally C:\) and has the hidden, read-only, and system file attributes set.
