ee1b86ffbd Disable I/O port accesses in case the BIOS enabled them. 
Clear all output lines except ATN and ACK when waiting
for target phase change.

ea6ecb4e52 Disable disconnect after drive timeouts, since these 
may be the result of reselect following too fast for
the driver to notice. Not the final solution, but the
problem has been seen only with very few devices.

6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified 
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.

99e7cabca3 Really deactivated the code that puts scsi stats into dk0. 
This should have been disabled for some time, but I had screwed up ...
This made spurious values appear for fd0 in systat, when there was
NCR SCSI activity.

c3739b59ec Change some compile time defaults, which may be overridden from the 
kernel config file by options lines.
Now the default settings are FAST SCSI, max. 4 TAGS, WIDE transfers,
if supported by the hardware ...

Bug fixed, that caused system hang on first interrupt on some motherboards.

New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
*** Remove PCI IRQ specifications from your kernel config file ! ***

PCI Int to IRQ mapping now specified per slot.

1ee6b373eb Add missing closing comment. I have taken the non-knf format 
of this code up with the authors and they are looking at converting it,
but until then leave the format alone.

df9ab3049d Removed inclusion of pio.h and cpufunc.h (cpufunc.h is included from 
systm.h). Merged functionality of pio.h into cpufunc.h. Cleaned up some
related code.
