I had a similar problem on my accelerated A600 (030@40):
Gurus on booting for RamLib or DHx:
Program failed error #80000004
Wait for disk activity to finish
(Suspend / Reboot)
When this happened, then I had to reboot with no startup-sequence (to let validate the disk with calm, even if I have the TurboVal installed) and get a :
Boot has a checksum error
on disk block xxxxx
(retry / cancel)
Solution: I left the whole system validate with the plain 68000 (yes, the gurus might be also due to the CPU overload, as my A600 is very prompt to these in such cases), or just try a QBack tools repair.
Just read the above post :-)
solved by replacing my HD! (it was drawing too much power).
So a low power might be the culprit in both cases:
The HD is drawing much power or the accelerator (in my case).
-Check the new motherboard and its power supply.
If there is something wrong with the checksum the QBack will fix it. If it's a bad sector (h/w problem), then these sectors should be marked as bad ones.
