Added support for INT 13,15; NTLDR calls it (though it may not
...
actually do anything with the result, since it carried on using us
even when we returned failure).

Use TEXT16_CODE() rather than manually specifying ".code16" etc, since

our manual ".code32" will break a KEEP_IT_REAL build.

Fix bug that caused over-allocation of .text16 and .data16 memory areas
by a factor of 16.

a0a872f7f1
Updated PXE UDP implementation to use the new Etherboot UDP API.
...
Updated PXE API dispatcher to use copy_{to,from}_user, and moved to
arch/i386 since the implementation is quite architecture-dependent.
(The individual PXE API calls can be largely
architecture-independent.)
2006-08-02 23:08:10 +00:00

Add "addr32" required explicitly by older gas.
2006-06-12 01:07:43 +00:00

Added null trap code for debugging. (Must be included by adding

--nulltrap to the make target at the moment.)

Windows Server 2003 sulks if we feed it an empty region in base memory

as a result of our memory map editing, so strip out any empty regions.

Added missing check-in

Fix bug with >256 cylinders.
...
Allow our functions to return a non-zero, non-error status (since the
INT 13 Extensions Check has to return the API version in the register
that is otherwise always used for the error code).
Report a non-zero API version from the INT 13 Extensions Check; GRUB
now uses extended reads.

We now have just romprefix, rather than having isaprefix and pciprefix
2006-06-06 15:41:21 +00:00

Cut out almost all the optional code paths, drastically simplifying the
...
flow of control through this code.
We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.
UNDI loader is still missing.

Updated to work with libprefix.
2006-05-25 22:04:47 +00:00

Documented the fact that the prefix can prot_call(main) without
...
worrying about its stack being destroyed during the Etherboot run.

Also hide base memory region from E820 map.
2006-05-25 00:10:58 +00:00
89da833c5d
init_librm() and prot_call() are now real-mode far calls.
...
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().
2006-05-25 00:06:45 +00:00

Has been obsolete for a while.
2006-05-25 00:04:37 +00:00
1966945a5d
Update relocate() to work with get_memmap().
...
Change semantics; relocate() now just finds a suitable location; it
doesn't actually perform the relocation itself. Code in libprefix does
the copy in flat real mode.

Define a struct memory_map with a fixed number of entries, rather than

requiring each caller to decide how many entries it wants to permit.

Remove the automatic segment register save and restore; most users of

REAL_CODE() don't need it.

Removed REAL_EXEC(); there is no longer any code using it.

Updated to REAL_CODE().
...
int13_boot() now does its own segment register save and restore, ready
for the removal of segment register restoration from the libkir
generic code.

Set carry flag before calling INT 15,e801 and INT 15,e820.

Ignore carry flag for INT 15,88; the Ralf Brown interrupt list says
that CF is unreliable for this call.

Split out REAL_CODE() from REAL_EXEC(), preparatory to removing REAL_EXEC
...
completely.
2006-05-24 09:51:04 +00:00
83d80d9e79
Remove references to obsoleted REAL_CALL from documentation.
2006-05-24 09:16:48 +00:00
3b525385af
Removed REAL_FRAGMENT and REAL_CALL, and left just REAL_EXEC (which is
...
the only one we actually use). This allows REAL_EXEC fragments to
contain proper references to constraints (e.g. "%w0"), rather than having
to force the use of specific registers.
Note that the "num_constraints" parameter is now completely obsolete, and
that we can probably reduce the syntax to something like
__asm__ __volatile__ ( REAL_CODE ( "asm statements" )
: output constraints
: input constraints
: clobber );
which would look much more natural, and avoid the need to always specify
a clobber list.
Add userptr_t to libkir.h, to allow it to at least compile.

77a65075a6
Replaced memsizes.c with smaller memmap.c, taking advantage of __data16,
...
and creating a memory map that's easier to work with than the E820 map.
2006-05-24 01:37:46 +00:00
5e80847827
Code to install the new E820 mangler (which doesn't require copying
...
down to base memory, since it is now in the base-memory-resident
.text16 section).
