Ok, I made changes in new revision, but with more strictive check.
It must work until next "great changes".
In addition VALIMIT key now supported too (but only for later OS/4 kernels, of course).
And HD4DISK.ADD must be updated to one from this revision, older versions will have troubles in detection of disk with non-default parameters (sorry, OS4User infected me with his "traditional incompatibility"
).
