c080110e39 Oops. Remove some debugging code used to display a hexdump of the sector
we just loaded from the disk.  The code to call it was commented out, and
it easily fit into the extra sector, but remove it anyway as it is
unneeded.

21066c4e63 This is `liloboot', which creates a file which can be treated like a
Linux kernel image, and is designed to be dropped into a Linux system
and booted via LILO.  Once booted, the user is greeted by the FreeBSD
loader.  This still isn't quite complete, as the the root= specification
from LILO isn't currently passed to the loader yet.

9563771e2e Merged from sys/boot/i386/libi386/biosdisk.c revision 1.31. 2000-07-14 04:23:45 +00:00

3f4475e6f5 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.

41134498c4 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.

037bed528d Doh. The disklabel is not 0x200 bytes of zeros, but it is 0x200 bytes long. 2000-07-06 00:29:40 +00:00

06878d47d6 Clarify the comments in here a bit. The first sector of boot2 is not just
zeros, it is actually the disklabel itself.  boot2.ldr is simply a

e1ff78731a - 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.

cf55ba84f4 Add in support for EDD to support large disks via LBA. This uses a
method similar to that of the loader to avoid potentially breaking older
drives in that we only use EDD if the desired cylinder is > 1023.

890a021e86 - Add some more details to the 'lsdev' output for FAT file systems.
- Add in support for the EDD (Enhanced Disk Drive) BIOS extensions to
  use LBA mode for accessing drives past cylinder 1024.  This should allow
  us to load a kernel from anywhere on a newer drive up to 2 TB.  Part
  of this came from the PR below.

beeee4808a Add support for emulating the RDMSR and WRMSR instructions into BTX. In
theory, this should allow the K7V Athlon motherboard to boot ok with boot
virus protection enabled.  However, I have no hardware to test this.  It
shouldn't break anything though. :)

cb251cf529 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.

FreeBSD/i386 bootstrap loader, Revision 0.8
(root@outback.netplex.com.au, Tue Jun 13 23:26:49 PDT 2000)
Loader version 0.3+ required
Aborted!
start not found

Note that the 0.3+ message is from inside the arch-alpha block, not the
i386 block of code.  And even then, 0.8 is higher than 0.3.

This prevents the rest of the loader.conf stuff working. :-/

647ef85d48 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!
