to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

Try to deduce maximum number of PCI buses in system (working around
chip set bugs).
Better check for devices at multiple addresses (aliases).

PCI BIOS mappings are retained, except if option PCI_REMAP
is specified in the kernel config file.
There is now a list of attach addresses, and the first
address that seems to make some device registers appear
is chosen.

worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.
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

ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.
1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments

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 ! ***
New version with improved support for WIDE SCSI using the NCR 53c825.
Test for buggy secondary cache implementations.
PCI Int to IRQ mapping now specified per slot.
wider variety of systems. Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev(). Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them. (This shuts up
complaints about my Matrox card.) Include the beginnings of what could
eventually become dynamically-loadable PCI devices. Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported
buses.
