ALL:
Removed patch kit headers and rcsid strings, add $Id$.
isa.c:
Removed old #ifdef notyet isa_configure code, since it will never be
used, and I have done 90% of what it attempted to.
Add conflict checking code that searchs back through the devtab's looking
for any device that has already been found that may conflict with what
we are about to probe. Checks are mode for I/O address, memory address,
IRQ, and DRQ. This should stop the screwing up of any device that has
alread been found by other device probes.
Print out messages when we are not going to probe a device due to
a conflict so the user knows WHY something was not found. For example:
aha0 not probed due to irq conflict with ahb0 at 11
Now print out a message when a device is not found so the user knows
that it was probed for, but could not be found. For example:
ed1 not found at 0x320
For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa! The 0x100 magic number is per ISA spec. It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard. We really need to split the
keyboard probe from the display probe. It is completly legal to build
a pc with out one or the other, or even with out both!
npx.c:
Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.
Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything. It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.

that it was probed for, but could not be found. For example:
ed1 not found at 0x320
For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa! The 0x100 magic number is per ISA spec. It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard. We really need to split the
keyboard probe from the display probe. It is completly legal to build
a pc with out one or the other, or even with out both!
npx.c:
Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.
Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything. It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.
