I had a problem also with the HardFrame/030 combo along with the 2091.
Whenever I accessed my partition icon of of the hardframe, the system
would lock up. I called Microbotics and they send thee'd send me out a
new version of their PAL chip U9. In the mean time I managed to get the
system working by putting the Q40 drive from the hardframe onto the 2091
and formating with the 2091 installation disk. I then switched back to
it back onto the hardframe and the problem went away. A few days later
I got the upgrade PAL chip. Always wanting the most current of
everything, I installed it. Like you, my system would boot into a GURU
every time. Check the chip on the HardFrame marked U9. If if has a
resistor soldered directly onto two of it's pins, its the newer version
that didn't work when I installed it either. I put the origional PAL
back in and the hardframe works fine.

Microbotics fixed this around a year ago. { Much stuff deleted } I tried the 2630 and really liked it (its a cool board, Dave :-) ) However, I also own a hardframe which is one of the older ones that, while the system worked, I had to remove a memory card since the hardframe did not like it. So, the question is: can I affect a fix so that my older hardframe (which is nice and fast and I like it) works? It is true that the 1 meg agnus chip does NOT like the hardframe (from friends with exactly the same setup) and I can't move up to the new chipset until I deal with this problem. Any suggestions?
