I finally have 1.5.0 working after using the new fdisk to mark my
/dev/hd1 partition as an old minix one (I have the root image on it).
My readclock didn't work on an AT clone (AST brand --same as creator of
Minix) and I tracked the problem to not having a /dev/port.  But after I
installed a /dev/port 1 4 (major/minor #'s) as a block (b) device, an
attempt to readclock will crash the system hard (cntrl-alt-del will not
reboot).  Does anyone know why?  Have I used the correct format for
mknoding /dev/port?  Under 1.3 the readclock worked fine.
