Toad for DB2不支持AS/400?该怎么解决

Toad for DB2不支持AS/400?
Toad   for   DB2   2.0的官方页面中这样写的:

------------------
Supported   Database   OS   Platforms

LINUX   Red   Hat   Enterprise   Linux   AS   v3,   4   (Itanium   and   AMD   Opteron   chipsets   support   for   64-bit   environments)

上面没有AS/400和OS/400.难道真的不支持吗?可是很多企业都在用AS系列阿
