PS/2 mod 50z with Reply PowerBoard upgrade (Microchannel)
>Description:
Driver for WD8003 gets wrong i/o addresses when the adapter is set for i/o address greater than 0x2ff.  Supported adapter i/o addresses are 0x200 - 0x3ff.
>How-To-Repeat:
Set WD8003 to i/o address greater than 0x2ff.  The test case was set at 0x340.
