This may have already been covered...

I have a GVP HC+ 2MB controller in a stock A2000 that has been running
ok for some time.  I recently purchased the FaaastROM upgrade eprom
for this controller, and put it in.  I got wierd results from a speed
check (diskspeed I think) that showed block reads/writes speeded up
tremendously with the new eproms, but claimed that file read/write/open/
create times got slower, I have no idea why???  Regardless, the controller
worked fine for some time therafter...

I *very* recently aquired, and hacked into my A2000, an old circa 1983
68020 adaptor board, which I managed to plug into the 68000 socket on
my rev. 4.2 motherboard.  Most everything worked great with this new
processor board installed, with the glaring exception of my GVP controller!
I would get intermittant, but very frequent, failure of the OS to recognize
the harddrive on boot-up.  After several reboots, or after booting from a
floppy, I would get some (but usually not all) of my partitions up, with
the remaining partitions comming up bad (eg dh3:bad).

I decided on a hunch to replace the new GVP FaaastROM eprom with my old
eproms to see if it helped.  Of course the problem went away ENTIRELY!  I
have had trouble free booting ever since.  My question:  Why????

If anyone has had similar problems, I would be very interested in hearing
about it.  I really liked the FAAASTPREP program that I got with the
FaaastROM kit, but it can't find gvpscsi.device on the old eproms.  I
would really prefer to be running with the FaaastROM (version 3.07 eproms)
if at all possible.  Please leave email if this subject has already been
beaten to death here.  Thanks...
