Don't forget that all ISA cards that do either busmastering or dma have to
use bounce buffers on machines that use more than 16MB of ram.  The 1522 is
a PIO-mode card, and if it's working for you I'd leave it alone.  I'm using 3 of
these cards in different FreeBSD machines, without troubles.  Here in Portland
you can buy a 486/133 PCI/ISA motherboard with CPU for about $120, and a ncr
PCI scsi controller for $70, that would give you far better performance for only
$30 more than any ISA scsi controller.
