This is the more likely scenario regarding the limits in performance.
The CHIM in the card's Firmware is different than the PD CHIM in the

There's 64-bit *transfers* and 64-bit *addressing* ... but let's not
go into that; the problem isn't on the PCI bus, it's on the SCSI bus.
Even 32-bit, 33MHz PCI is capable of at least 80MB/s.
That sounds fine, but when connecting the same exact cabling, etc. to the

Thanks for your response, Mark.
Define 64-bit, and how do you making the declaration
that it is not supported.
I was apparently incorrectly basing it on the register's address space from
the lspci output. Can you perhaps help me tell a better way to tell if my

64-bit data transfers are performed by Hardware and can not be
instrumented. Only a PCI trace will know.
64-bit dma addresses is supported, but the card's registers must reside
in the 32-bit space regardless (Memory at
