I read a thread about a year back in regard to the JackHammer not 
working correctly. But nothing else was really said beyond the driver 
needed additional code for the card. My jackhammer probes as this:

isp0 at pci0 dev 15 function 0: QLogic 1020 Ultra Wide SCSI HBA
isp0: interrupting at irq 25
isp0: Ram Checksum Failure

	I downloaded flashers, code and nvram data from Qlogic's web site 
for the only card that looked close, FastMac1020 I think it was called, in 
the obsolete hardware side. Tried to flash or even use the SIM Init to 
erase the card and start it fresh, but none of the Qlogic utilites worked.  
that they couldn't find any Qlogic hardware. I found a few hits on google 
to hammerstorage.com which is now some web site where every hit it gets 
makes a commision on redirecting to somebodys ebay site. I t was supposed 
to be the last place you get the latest firmware for this card.

	Like they mentioned in the last thread on the subject, the card 
has a PCI ID of 1077 which is Qlogic, not FWB. So are we left to conclude 
that there's something different about the card that makes it unusable 
except by FWB's HDT or Raid toolkit software? I have three of these SCSI 
Jackhammer PCI cards, I have one NuBus SCSI Jackhammer card, and I have a 
MicroNet Raven Pro PCI 1020A based PCI card.

	This article is of a bit of interest, but no help:

	Also, it looks like the Raven card uses a rebranded set of tools 
from what is now FWB HardDisk Toolkit on MacOS.

	It wouldn't be something so simple as a missing endian check and 
possible swap from eb to el on the checksum would it? The same card in an 
x86 system reports the same thing, Ram checksum error.
