The information in this article applies to:


 * Microsoft Windows 95

SYMPTOMS
When you are using a TekRam VLB controller with Windows 95, you may experience performance or MS-DOS Compatibility mode issues with hard disks with a capacity greater than 528 megabytes (MB).

When you experience such issues, the Ios.log file may contain the following information:

  ESDI sector mismatch Unit number 02 going through real mode drivers. Unit number 03 going through real mode drivers. Unit number 04 going through real mode drivers.

CAUSE
The Esdi_506.pdr driver supports only standard INT13 functions. It does not support sector remapping. This behavior is by design.

RESOLUTION
To enable protected-mode support for the TekRam VLB controller, please contact TekRam to inquire about obtaining a Windows 95-compatible driver for the controller.

For additional information about using the TekRam VLB disk controller, please consult the controller's documentation or manufacturer.

MORE INFORMATION
When you use a TekRam VLB controller with hard disks with a capacity greater than 528 MB, the track remapping and enhanced INT13 options must be enabled on the controller. Such translation schemes are not compatible with the Windows 95 Esdi_506.pdr driver. protected-mode support for this controller is limited to hard disks with a capacity less than 528 MB.
