Have you (or has anyone else out there) attempted to use the Pacific
Peripherals Overdrive autoboot daughterboard together with the new Fat
Agnus chip upgrade?  My dealer installed the Fat Agnus chip in my
Amiga 2000, but now the Overdrive won't autoboot reliably any more.
(It worked fine with the old Agnus.)  Instead, when autobooting,
frequently the boot partition ("slow file system") gets corrupted, with
a "key checksum error" or something like that.  (DiskDoctor reports
that the partition is really corrupted, and often can't fix the bad
key error.) Sometimes the autoboot succeeds, but a subsequent disk
access causes the same sort of corruption.

If I let the Amiga warm up for 15 minutes or so, then the autoboot
seems to work OK.  But if I let the Amiga cool off (say overnight),
then the autoboot fails and corrupts the partition again.

When I contacted Pacific Peripherals, they told me they haven't even
attempted to use the Overdrive with Fat Agnus yet!

Does anyone have any ideas?
