Does anyone know of any drivers for FreeBSD 1.1.5.1 that will support a VESA
SCSI controller (say the Adaptec - I don't know a model number off hand)?

WIll this have the same 16Mb limits that the ISA controller has (due to bus
addressing restrictions)?

While on that subject, the FreeBSD Release Notes indicate that you cannot use
the ADAPTEC 1452 CFK with more than 16Mb of memory.  It then goes on to say
that the system will use "bounce buffering" if necessary, allowing the use of
more than 16Mb.  Which is correct?  Does this mean that you can transparently
use more than 16Mb of memory while also using the ADAPTEC ISA SCSI controller?
