Minimserver on Synology DS508

[Patatorz]

Hello, I use minimserver on a Synology DS1512+ without any problem.
I also have an older DS508 and I tried to install minimserver on. As DS508 is a old PPC cpu, i used this workaround (http://www.hera.cc/2010/11/installer-jav...ogy-ds210/) to install java. Everything seems ok but impossible to install minimserver as DSM 4.1 and higher is required.
So my question : as the DS508 is DSM 4.0 minimserver is not onstallable. But is it a minimserver limitation or an older version of minimserver could be installed on a DS508 with the Java workaround ?

Best regards
