I'd also love to know whether there is really a significant performance
difference between a 2940 and a 1742.  While the PCI burst data rates are
much higher than the EISA ones, both are well above the Fast SCSI 10 MB/s
speeds -- let alone raw disk data rates.

Given that I already have a 1742, the cost of buying a 2940 is about the
same as buying a PCI/EISA motherboard over a standard PCI one.  The 2940
driver also requires an FDISK table (which I *might* be able to wedge onto
my existing boot disk, but ...).  Not to mention that the 1742 driver is
most definitely stable and robust!
