-Due to the 24 bit addressing limitation of the ISA bus, The SCSI
-adapter's onboard DMA controller is unable to access memory with
-addresses greater than 16 megabytes.  
-.Pp
-This restriction can be fixed with "bounce buffers", buffers in low

-to the bounce buffer, then copied from the bounce buffer to its
