SYMPTOMS
========
When you are configuring a Future Domain SCSI controller in Device Manager, you
may not be able to configure the controller to use the E800h-E9FFh or
EA00h-EBFFh I/O address range, even though you can configure the controller
itself to use either of these ranges. This problem is known to occur with the
following Future Domain controllers:
- TMC-850
- TMC-850M
- TMC-850MER
- TMC-850MEX
CAUSE
=====
This problem occurs because the Windows 95 SCSI.INF file and hardware detection
routine do not distinguish between the Future Domain 850- and 860-series
controllers. Although the 850-series controllers can be configured to use the
I/O addresses listed above, the 860-series controllers cannot.
RESOLUTION
==========
The Future Domain 850-series SCSI controllers cannot be configured to use the
E800h-E9FFh or EA00h-EBFFh I/O address range when you are using the Windows 95
protected-mode drivers. If you are using protected-mode drivers, use one of the
following valid address ranges for the controller:
- C800h-C9FFh
- CA00h-CBFFh
- CE00h-CFFFh
- DE00h-DFFFh
If you must use the E800h-E9FFh or EA00h-EBFFh I/O address range, use the
real-mode drivers included with the controller instead of the Windows 95
protected-mode drivers.
STATUS
======
Microsoft has confirmed this to be a problem in Microsoft Windows 95. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
