DOC: IOConfig Alias-offset Example Incorrect

The information in this article applies to:

• Microsoft Win32 Device Development Kit (DDK) for Windows 95, version 4.0

SUMMARY

The Windows 95 DDK contains the following IOConfig alias-offset example:

    The following example shows the use of a Type 1 I/O range value in an
    IOConfig item. This specifies 16 IO port regions of 1 byte each, where
    each region starts at x2E8 where x is 0-Fh.
    IOConfig=2E8-2E8(FFFF:4:)

    IOConfig=2E8-2E8(FFFF:1000:)
    in order to reserve IO regions of x2E8, where x is 0-Fh.  Windows 95
    actually takes the high byte of the low word of the alias-offset
    parameter, and assumes that the low byte is zero. So, any alias-offset
    of 10xxh is treated as 1000h.

    When you try to add a new hardware device that requires a base address
    that is the same as an alias of another hardware device previously
    installed, Windows 95 reports a conflict.  However, when you run the
    Windows 95 Conflict Troubleshooter and use Device Manager to manually
    set the configuration for the conflicting device, no conflicts are
    reported.
