- Extract:
-
- A Windows FastDisk device such as WDCTRL or WDCDRV.386 will not load if
- the original Int 13h address (which was in the interrupt vector table when
- IO.SYS was loaded) has been changed by other software. This original
- address is the means by which IO.SYS can guarantee that it is communicating
- directly with the low-level hard disk BIOS routines. This address can
- be changed by other drivers or TSR utility software. If it is, the following
- message is displayed by WDCTRL:
-
-
- "The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There
- is unrecognizable disk software installed on this computer.
-
- The address that MS-DOS uses to communicate with the hard disk has been
- changed. Some software, such as disk-caching software, changes this address.
-
- If you aren't running such software, you should run a virus-detection
- program to make sure there is no virus on your computer."
-
-
- The following message is displayed by WDCDRV.386:
-
- "WDCDRV cannot be loaded. There is unrecognizable disk software installed
- on this computer."
-
-
- If you receive either of these messages, FINDHOOK.COM may be able to
- pinpoint the TSR, ROM BIOS, or device driver that has changed the Int 13h
- address within IO.SYS. By being able to identify the software, you can
- determine what needs to be removed in order to obtain 32-bit disk access.
-
- FINDHOOK will display the name of the program that is causing the conflict.
- It may not be able to locate TSRs loaded high by QEMM or 386Max, and has
- not been tested with these packages.
-
- Do not run the program from within MS Windows.
