Hi, greetings, i have a problem, maybe someone can give me a idea

When i try to load aweutil to emulate mpu, like aweutil /em:gm, aweutil /em:gs or aweutil /em:mt32

I get

ERR014 "Feedback path error"

Ok, no big deal, i have the same problem before on some motherboards... BUT aweutil was working FINE last time i use, in same computer, IBM Consultant 486

I dont know, maybe two weeks ago last time i use Wolfdosmpu (wolfenstein mpu mod) was working fine, today i get the error

autoexec/config are same last time, no hardware changes. I tested ram, no problem, and even change ram modules for other just in case, no difference

The AWE64 card if fine, ram test is OK, and aweutil works fine in other computer. I tested another AWE64 card in IBM and SAME PROBLEM

Maybe my english is not very good, to resume

1 - hardware is same
2 - RAM test OK
3 - AWE64 is OK works fine in other PC
4 - Other AWE64 cards do same problem in ibm pc
5 - IBM bios is very limited, options are the same
6 - I swap the HDD in other PC, and AWE64 works fine, then is not a software problem
7 - No emm386, etc only himem.sys, anyways, like i said, was working OK with same config two weeks ago

Im out of ideas, is like the IBM stop lovingAWE64 cards from one day to another....

Any ideas are welcome thanks
