I'm not sure if you can switch to SRM on the fly. All machines I've seen

As I understand it the old PAL is not something the BSDs will like to run
on. WinNT PAL code is simply unusable altogether.

I'm by no means an expert in this matter. It has been discussed a number of
times before on the mailing lists. I guess you might want to check the 
mailing list archives.

In any case it seems like a waste of time to me to be honest. It is, of
course, a challenge ;-)
