Michael Brown 22ed1fbaf1 Add ability to read serial number from SMBIOS 2007-02-01 20:52:12 +00:00
Michael Brown f06059ab97 More assertions 2007-02-01 02:18:22 +00:00
Michael Brown c650c8c84a Also print out stack pointer (with optional stack dump) 2007-02-01 02:17:59 +00:00
Michael Brown 406b20a64d Assert that division result is correct 2007-01-31 23:58:52 +00:00
Michael Brown c789e8640b Added __umoddi3 2007-01-31 22:26:14 +00:00
Michael Brown 7d9267561b Don't call PXENV_STOP_UNDI in the kpxeprefix. This slighy breaks the 
clean separation between loading and starting, but does mean that more
PXE stacks survive the process.
 2007-01-29 15:21:10 +00:00
Michael Brown 2cf1e33df1 Split bootsector execution code out into bootsector.c. 
Added basic El Torito ISO image boot capability
 2007-01-29 04:21:38 +00:00
Michael Brown b3b6b25aeb Handle (64-bit) / (32-bit) = (64-bit), i.e. one step beyond that 
provided by the divl instruction.
 2007-01-28 19:34:17 +00:00
Michael Brown f59281d8f6 Yet more synonyms that people tend to use. 2007-01-26 01:30:16 +00:00
Michael Brown 6a765fdc15 Use base "0" in strtoul for consistency with "mem=" 2007-01-24 22:54:08 +00:00
Michael Brown 99cb46943f "vga=" is specified in decimal, not hex. 2007-01-22 23:56:24 +00:00
Michael Brown ebb00e032c Misread the definition of the type_of_loader field; it should include a 
version.
 2007-01-19 15:40:01 +00:00
Michael Brown 73b09ecba6 Use stdio.h instead of vsprintf.h 2007-01-19 01:13:12 +00:00
Michael Brown 5d57cd47a2 Declaring the CPU architecture in the middle of an assembly file is 
somewhat redundant, and also causes gas to complain when we include
the profiling code (which uses an i586 instruction).
 2007-01-18 18:53:32 +00:00
Michael Brown bd95927386 Accelerate memcpy() by around 32% on large, dword-aligned copies. 2007-01-18 15:18:02 +00:00
Michael Brown 544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously 
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
 2007-01-16 08:36:42 +00:00
Michael Brown a5f6408d8e We can now load an initrd as well as a kernel 2007-01-14 16:09:01 +00:00
Michael Brown b9f99858ab Make the getmemsize() prototype available in memsizes.h, for code that 
doesn't want to go to the hassle of processing a full memory map.
 2007-01-14 15:32:25 +00:00
Michael Brown 10c9b03cdb Actually, the initrd image should be architecture-independent. 2007-01-14 15:07:11 +00:00
Michael Brown f92e04dea4 Add dummy "initrd" image format, just so that images can be marked as 
initrds.
 2007-01-14 15:03:39 +00:00
Michael Brown 8a490146bf Copy command line at execution time rather than load time. 
Parse command line for "vga=" and "mem=" parameters
 2007-01-14 14:29:30 +00:00
Michael Brown 3ccd7335f0 Split bzimage_load into separate functions 2007-01-14 13:36:33 +00:00
Michael Brown 97a3037f76 Can start a Linux kernel directly (albeit with no initrd support) 2007-01-14 12:34:35 +00:00
Michael Brown 3cbf0db0a3 Remove some references to no-longer-existent source files. 
Add a path for isolinux.bin that is correct on my system; hopefully it
will work on others too.
 2007-01-14 11:52:22 +00:00
Michael Brown b04b0ddc31 .lilo and derived targets (e.g. .iso) now load properly. 2007-01-14 11:50:44 +00:00
Michael Brown 77d280968a Obsoleted by arch/i386/image/multiboot.c 2007-01-14 11:45:28 +00:00
Michael Brown 784e10635a Can almost start a kernel now. It dies with "No setup signature found" 2007-01-14 06:36:20 +00:00
Michael Brown b07161f397 Placeholder bzImage support 2007-01-14 04:27:25 +00:00
Michael Brown 797edf28b7 Replace image->entry with image->priv. 2007-01-14 04:04:28 +00:00
Michael Brown 3bdbfe1f00 Mostly updated. Won't work yet. 2007-01-14 03:49:07 +00:00
Michael Brown 644f3674e6 Obsolete for some time 2007-01-14 02:24:41 +00:00
Michael Brown 7bc03d37a2 Select a PXE network device before starting PXE NBP. 
Move pxe_boot() code to pxe_image.c
 2007-01-14 02:20:10 +00:00
Michael Brown 55e6d7b70c Use debug autocolourisation. 
Shut down before jumping to the multiboot image.
 2007-01-14 00:57:43 +00:00
Michael Brown dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.
 2007-01-14 00:53:56 +00:00
Michael Brown ece4ff929e Use _text, rather than assuming _text==0. 2007-01-14 00:03:07 +00:00
Michael Brown f547f148d3 Use {get,set}_fbms() so that allocated base memory is correctly hidden. 2007-01-14 00:01:16 +00:00
Michael Brown 0b0e34e667 Provide {get,set}_fbms() in basemem.h. 
set_fbms() will also update the E820 hidden region.
 2007-01-13 23:57:31 +00:00
Michael Brown aaed3d50a8 Some operating systems get a nasty shock if a region of the E820 map seems 
to start on a non-page boundary.  Make life safer by rounding out our
edited regions.
 2007-01-13 23:38:33 +00:00
Michael Brown d0f4e9a54b Add some trace messages for important events 2007-01-13 17:54:41 +00:00
Michael Brown f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.
 2007-01-13 17:28:51 +00:00
Michael Brown bd863e4112 Add header for pxe_boot() 2007-01-13 17:23:44 +00:00
Michael Brown 4b77061881 Pick up the return status code from the correct place now that we 
don't overwrite the parameter block until *after* the debug code.
 2007-01-13 16:55:57 +00:00
Michael Brown 5817c9f114 When an UNDI API call fails, print everything there is to know about it. 2007-01-13 16:53:55 +00:00
Michael Brown 6a3c76c8e0 Always send EOI. We can't feasibly share interrupts (since we have no 
clue what the "previous" interrupt handler will do, which could range
from "just an iret" to "disable the interrupt"), and that means that
we have to take responsibility for ACKing all interrupts.  Joy.
 2007-01-13 14:45:26 +00:00
Michael Brown 86171c53f4 Damn Broadcom and their damned incorrect assumptions about x86 memory 
allocation.
 2007-01-13 01:48:12 +00:00
Michael Brown bcd6ca3291 Place multiboot tables in base memory; at least some OSes won't see it 
if we don't.
 2007-01-12 16:25:05 +00:00
Michael Brown 0f29e0e46e Ensure multiboot modules are in ascending order of memory start 
address, to work around OS bugs.
 2007-01-12 12:03:19 +00:00
Michael Brown 53e948bba8 Fix the memory map. 2007-01-12 11:38:04 +00:00
Michael Brown 6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00
Michael Brown 9debfed07a Place command-line inline, to save on memory allocation hassles. 2007-01-12 05:26:19 +00:00
