This article describes how to determine if a drive overlay program is running on your Windows-based computer.
A drive overlay program is provided by third-party manufacturers and is loaded into memory before your computer's startup system files are loaded. A drive overlay program may be installed for any of the following reasons:
Drive Overlay MessageWhen you start your computer, a message may be displayed on the screen that displays the manufacturer's name or prompts you to press a key to boot to a floppy disk. Current versions of drive overlay programs may not display this message by default.
BIOS DateComputers made before 1994 do not support LBA. To verify if the BIOS on your computer supports LBA, consult the manufacturer's documentation or contact the manufacturer of your computer.
Fdisk Status CommandStart your computer with the Windows 95/98 Startup disk, type "Fdisk /status" (without quotation marks) at the command prompt, and then verify that the sum of the existing partitions is larger than the total hard disk space.
Windows 95/98 Startup DiskTurn off your computer, wait 10 seconds, start your computer with the Windows Startup disk (this prevents the drive overlay program from loading), and then boot to a command prompt. Compare the date and size of system files in the Windows folder for minor inconsistencies. If the physical disk size is much greater than 528, type "c:" (without quotation marks), and then press ENTER. Type cd \windows\command to determine if it is accessible.
NOTE: This only applies if this subfolder was created after the first 528 MBs are filled.
Verify FilesSome drive overlay files use an .ovl or a .bin extension. At the command prompt, type "Dir /a *.bin" or "Dir /a *.ovl" (without quotation marks) to check for the existence of files other than drvspace.bin and dblspace.bin.
Check Config.sysDrive overlay software may be loaded from the Config.sys file to access drives other than the active boot partition of the master drive on the primary IDE controller.
Memory CheckBoot to command prompt only, and then test your computer's memory. To do so, use the following steps:
