I tried booting my "new" SpinRIte 6.1 Release 4 diskette on my Thinkpad 760XD today. FreeDOS booted, the 6.1 splash screen was shown, then the screen blanked except for the blinking cursor in the top left corner, the floppy was read briefly (I think twice), then it just stopped. I waited for some time before giving up. I then booted my trusty old SpinRite 6.0 diskette, and it started up fine just as it has done many times in the past. So this is not a "big deal", I can just keep running SpinRite 6.0 on this old laptop and use 6.1 on most of my other machines. Is there some way of "tracing" the startup to determine where 6.1 is failing on the Thinkpad 760XD? The 760XD is an old chunky Thinkpad from 1997 with a 166Mhz Pentium MMX CPU, so it is most certainly "legacy only".
