Memory Range

With all SCSI controllers, please refer to the manufacturer's
description for the memory range.
Under Windows NT 4.0, the SCSI controller family AHA 154x, for
example, does not report the memory range used (default: D 8000
D BFFF ) to the operating system. In this case, make sure that the
H
memory range of the CP 5412 (A2) does not overlap this range.
If the memory ranges of the CP and the SCSI controller over-
lap, this can result in a memory error that will cause Win-
dows to crash. To restart Windows successfully, at least one
of the drivers involved must be removed or deactivated. Check
with your system administrator about the best course of ac-
tion.
An overlap of the memory areas may also destroy the data on
the hard disk.
If the SCSI controller is located on the motherboard, it is pos-
sible that the BIOS will be deleted if memory ranges overlap. In
this situation, we therefore recommend that you use the higher
memory ranges for the CP 1413 or CP 5412 (A2).
