8879e57b3e Simplify the "is a character ready" test, so that we don't return a false 
negative for keypresses with zero ascii values.  This is in line with the
comconsole test, rather than being more ambitious.

a1c0b1c5c5 PnP enumerator using the PCI BIOS. This is needlessly complex due to the 
lack of a simple "enumerate all PCI devices" function.

f41c619d3d Pop the return address off the stack before making a V86_CALLF call; 
this allows us to implement what look like C function calls from user
space "directly" to v86 mode code.  (Used for calling the PnP BIOS)

d8ef941c2f - Enable PnP and ISA PnP code. 
- Use the ISA PnP enumerator.
 - Use the new linker set code, throw out the gensetdefs stuff.
 - Produce an intermediate loader image that has symbols stripped, to aid
 - in debugging.
 - Supply ISA port access functions required for ISA PnP

c90625d230 Don't depend on being part of the kernel tree. If we are, use the kernel's 
<machine> includes rather than the system's.

eddbe21def Make ISA PnP work. This successfully enumerates as many ISA devices as I 
can fit into my test machine.

 - Move to using STAILQs rather than ad-hoc singly-linked lists.
 - Use a mostly procedural interface to the PnP information.  This
   improves data-hiding.

Implement a new linker-set technique (currently on i386 only but should work
on Alpha as well).  This is a good candidate for replacing the current
gensetdefs cruft completely.

93d51dcaf9 Treat all options as toggles (ie. -c -c is the same no -c). Since 
the boot.config settings are persistent, this seems to provide a
useful override capability, and should break only on broken
boot.config's.

Output a cosmetic newline if booting with no input.

7fa25d805a biosboot compatibility fix: 
Read boot.help before parsing boot.config.  We were parsing
boot.config first, which could result in boot.help being read
from a different location (or not found), which would probably
just cause surprise, without being useful.

a6575097c6 Load the first page of the file and use the headers in it. This should 
avoid the need to seek back to offset zero which is causing trouble on

3323768d99 "fix" the gzipped kernel load problem by having the loader check that it 
can seek back to the first PT_LOAD and doing a close/reopen if it cannot.
This is because the first PT_LOAD section includes the ELF headers.
This fixes gzipped kernels on the i386, it should solve mike's problem
for the Alpha.

da6c15d597 Initial attempt to update the Alpha loader and kernel to use the machine 
independent elf loader and have access to kld modules.  Jordan and I were
not sure how to create boot floppies, and the things we tried just made
SRM laugh in our faces - but it was upset at boot1 which was not touched
by these changes.  Essentially this has been untested. :-(

What this does is to steal the last three slots from the nine spare longs
in the bootinfo_v1 struct to pass the module base pointer through.

The startup code now to set up and fills in the module and environment
structures, hopefully close enough to the i386 layout to be able to use
the same kernel code.  We now pass though the updated end of the kernel
space used, rather than _end. (like the i386).

If this does not work, it needs to be beaten into shape pronto.  Otherwise
it should be backed out before 3.0.

eb9022e791 Try and get the sys/* and machine/* includes via relative paths. This

the boot code.

2a26e9ea83 Align to sizeof(long) rather than sizeof(int32_t). It needs to be 
long because this code is shared with the alpha.  I hope the alpha can
read 32 bit ints at 32 bit alignment (vs. 64 bit alignment).
