ab9e9f9d2d Argh! Fix a brainfart of mine. In the old boot0, we relocated ourself
to 0x600 via a 'rep movsw'.  Once that was done, %cx was zero, so we could
simply use 'movb' to update the lower byte of %cx in preparation for
zeroing out the fake partition entry used to boot to other drives via F5.
Well, in the new boot0, we don't actually relocate ourselves, instead it
is easier to create the fake partition entry first and then just use it to
get the BIOS to load all of boot0 into memory at 0x600.  However, since we
aren't doing the relocate code anymore, we don't know that %cx == 0 when
we hit the 'movb' to setup %cx for clearning the fake partition entry.
Thus, if %ch != 0 when the BIOS started boot0, then it would end up zeroing
a lot more memory than just 8 words.  The solution is to do a word move of
$8 into %cx.

e9b13dd6ec Added PC-98 HDD boot manager. The boot0 is the `IPL' which occupies
sector 0 of a disk and boot0.5 is the `boot selector' which starts
from address 0x400.  The IPL loads boot0.5 and boot0.5 loads bootblock
of a slice.

The boot manager stuff was developed by me (kato) with Borland C++,
and then, translated into bcc in the ports collection by Nokubi-san.
After that, boot0 has been translated into gas with the .code16
directive by Takahashi-san (nyan) and boot0.5 has been rewritten in
gas by me.

1dce5cb37f The new and improved boot0, v1.1. This version adds the following:
- Autodetection and support of the BIOS EDD extensions to work around the
  1024 cylinder limit on all but really ancient BIOS's.
- To work around some BIOS's which break when EDD is used with older drives,
  we only attempt to use EDD if the cylinder is > 1023.
- Since this new code required more space than we had left, expand boot0 to
  2 sectors (1024 bytes) in length.
- Add support for boot0 being multiple sectors using predefined constants.
  If boot0 needs to be extended in the future, all that is required is
  bumping the NUM_SECTORS constant.
- Now that we have more room to work with, add a few more fs type
  descriptions while making others more verbose.

492f000557 Always install loader.4th, defaults/loader.conf, and support.4th instead of
only doing so if loader.rc does not exist.  This fixes the problem where
installworld doesn't update /boot/loader.4th, resulting in device.hints not
being loaded after updating past the config(8) changes, which resulted in
mcclock0 not being probed, and a nice kernel panic during boot.

bce816b9cc - Don't blindly assume that there are 8 hard drives installed. Instead,
use the BIOS Equipment List to determine how many hard drives are
  installed and if the drive number we received in %dl is valid.
- Don't bother to disable interrupts when setting up the stack.  The 8086
  and beyond implicitly disable interrupts after an instruction that sets
  %ss (for example, a pop or a mov) so that you can safely set %ss and %sp
  in two consecutive instructions.  An exception to this is the lss
  instruction, which can set both registers simultaneously and thus doesn't
  need this hack.
- Add support for EDD BIOS extensions to support booting off of hard drives
  of nearly arbitrary length.

18ee60a576 Remove the setting of sourceid from bf_vm(), as bf_vm() really has
no clue.

Set sourceid to 0 when booting, which is the correct setting for stdin.

Set sourceid to an arbitrary fd when include'ing, preserving and restoring
the previous sourceid. This is possibly broken(), as 0 is a valid fd. Maybe
we should +1 to this value.

This fixes the version problem widely reported.

(root@outback.netplex.com.au, Tue Jun 13 23:26:49 PDT 2000)
Loader version 0.3+ required

f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

7f562b6673 The loader was written so that if /kernel was missing /kernel.old would
be booted.  Due to a bug, this wasn't happening.

There is still a lesser bug in that the loader decides which file to boot
after the 10sec count down.  This means the bootfile listed in the count
down in is wrong in the case where the loader will boot /kernel.old.

773065b3b8 Switch to using the .code16 as(1) directive and using 16-bit assembly
code instead of using 32-bit code and having to just "know" that it's
really 16-bit instructions when things run.  This also allows the code
to use fewer macros and more actual assembly statements, which eases
maintenance.  Unfortunately, due to as(1) brokenness, we still use m4
macros for all 16-bit addresses, and all short jumps (i.e., 8-bit
relative addresses in the jump instruction) must be wrapped in .code32
directives to avoid useless bloat by as(1).  This also fixes a few
problems that were preventing boot0 from compiling with the latest
and greatest version of as(1).

d08ae64b1d Bring support in for Intel Wired for Management 1.1 (PXE 0.99 and

disabled when PXE calls were being made, and they must be enabled.
This should also allow us to be compliant with all newer PXE rom's
from Intel.

For PXE 0.99, this has been tested using the Intel N440BX motherboard
and I am confident it will work on the Intel L440GX motherboard.

Lots of help/information from: jhb, peter

36273c5d79 Don't disable interrupts when calling a vm86 mode interrupt or routine
from user mode.  Don't disable interrupts when returning from vm86 mode
to user mode either.  Now, we only disable interrupts before calling a
hardware interrupt handler, which is the only time we _should_ be
disabling interrupts.

Because of this, err, feature, any routine that one called in vm86 mode
had to re-enable interrupts by setting the interrupt flag or interrupts
would remain disabled even after the routine returned.  For example, I
have a simple debugging routine that uses a vm86 mode function to dump
any arbitrary memory word that I use to read the BIOS timer or any other
memory location.  This function does 1 load instruction from memory and
then returns.  Since it didn't re-enable interrupts, the first time I
called it to read the BIOS timer, it disabled interrupts.   This also
affected the PXE bootstrap as it needs interrupts enabled while it is
processing.  This patch fixes both of those situations so that those
functions do not worry about having to enable interrupts.  Hardware
interrupt handlers worked fine with the old code because they always
enable interrupts as part of their routine.

If you have any problems with the loader after this commit, please
let me know.  I'd like to MFC it in a week or two since PXE support
needs it.

48a0c4ea04 Mega i386 loader commit.
- Don't hard code 0x10000 as the entry point for the loader.  Instead add
  src/sys/boot/i386/Makefile.inc which defines a make variable with the
  entry point for the loader.  Move the loader's entry point up to
  0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
  instead use m4 to achieve this.  Also, add a BTXLDR_VERBOSE knob in the
  btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
  instead of having i386/loader/Makefile do that.  Also, add in some more
  variables to make the pxeldr Makefile almost identical and thus to ease
  maintainability.
- Teach cdldr about the a.out format.  Cdldr now parsers the a.out header
  of the loader binary and relocates it based on that.  The entry point of
  the loader no longer has to be hardcoded into cdldr.  Also, the boot
  info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
  (such as DOS FAT) that we currently support.  This is still buggy as
  it assumes that a floppy with a DOS boot sector actually has a MBR and
  parses it as such.  I'll be fixing this in the future.
- The biggie:  Add in support for booting off of PXE-enabled network
  adapters.  Currently, we use the TFTP API provided by the PXE BIOS.
  Eventually we will switch to using the low-level NIC driver thus
  allowing both TFTP and NFS to be used, but for now it's just TFTP.

536fcb08bf This patch to BTX fixes several small things:
1) Fix a bug in the int15 function 87 emulation where we only copied half
   of what the BIOS asked for.  This caused the Mylex RAID adapter to go
   haywire and start trashing memory when you tried to boot from it.
2) Don't use interrupt 19 to reboot.  Instead, set the reboot flag to a warm
   boot and jump to the BIOS's reboot handler.  int 19 doesn't clear memory
   or restore the interrupt vector table, and thus really isn't safe.  For
   example, when booting off of PXE, the PXE BIOS eats up a chunk of memory
   for its internal data and structures.  Since we rebooted via int 19,
   using the 'reboot' command in the loader resulted in that memory not
   being reclaimed by the BIOS.  Thus, after a few PXE boots, the system
   was out of lower memory.
3) Catch any int 19 calls made by a BTX client or a user pressing
   Ctrl-Alt-Delete and shutdown BTX and reboot the machine cleanly.  This
   fixes Ctrl-Alt-Delete in the loader and in boot2 instead of presenting
   the user with a BTX fault.
