When I reboot I get an error message saying "Moved or missing IBMBIO.LDR" then "Press any key to continue". Is this an OS file missing or is it some BIOS thing? I get the message before anything loads and when I press a key my autoexec.bat runs fine, loads everything and all. The hard drive works fine, too. I tried reinstalling DOS, but to no avail. What is happening?

Hello El, If you installed DR Multiuser DOS, you may have noticed a utility called LOADER. This utility is similar to the OS/2 Boot Manager utility and is automatically installed by DR Multiuser DOS systems that contain a pre-existing single-user version of DOS. LOADER lets you to select between DR Multiuser DOS and a single-user operating system. If you are in the business of supporting more than one operating system, LOADER is an ideal testing utility. When LOADER is installed, it includes two hidden, system, read-only (HSR) files: LOADER.SAV and IBMBIO.LDR. These files are location-sensitive and must not be moved or deleted except through LOADER. LOADER.SAV contains an exact duplicate of the Master Boot Record (MBR) before LOADER was installed. Moving or deleting LOADER.SAV will prevent the system from being restored to its previous state should be necessary. If the files are removed, LOADER will return an error indicating "Bad or missing IBMBIO.LDR" on bootup. This message does not signal the demise of your hard drive; LOADER simply cannot find a key file. LOADER always allows you to load the default operating system (by striking any key), but if one of these files is missing, no other configured operating system will be able to boot. holmes.

can i disable loader?
