I did further testing, however I was not able to figure out why it freeze with the menu config.sys and not with the menu-less config, but found a solution.
I can't use the X=TEST parameter, this will still make the system to freeze, but I have to exactly define the range where it's occupied by ROM to be excluded and that is with X=A000-CFFF.Is this due to the more aggresive scan in v5.80 compared to what v5.79 does?
