7bc03d37a2 Select a PXE network device before starting PXE NBP. 
Move pxe_boot() code to pxe_image.c

98240d99f0 Do not go past the end of the argv[] array. 
This bug found by setting read and write watchpoints at NULL in bochs.

55e6d7b70c Use debug autocolourisation. 
Shut down before jumping to the multiboot image.

dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.

c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00

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.

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.

f11900a9c6 I prefer IMAGE_XXX to XXX_IMAGE. 
Add IMAGE_PXE to use the new image format framework.  "kernel pxelinux.0"
now works.

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.

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.

86171c53f4 Damn Broadcom and their damned incorrect assumptions about x86 memory 
allocation.

63386f4455 Added ENOENT, since HTTP 404 translates to it 2007-01-12 19:14:01 +00:00
Michael Brown
ca3db0bf11 Added isspace() and made strtoul() accept whitespace, as per POSIX. 2007-01-12 19:11:28 +00:00
Michael Brown
83b7933f8a Damn it; my lovely resilient scheme falls down when you have a protocol 
that switches from line-oriented to byte-oriented partway through, such as
HTTP.
 2007-01-12 18:09:14 +00:00

ad22cccc09 No need to maintain a received byte count; we always fill in sequential 
order so we can just use buffer->fill.

996b091b50 Added generic line-buffering code (a la stdio) 2007-01-12 17:08:37 +00:00

bcd6ca3291 Place multiboot tables in base memory; at least some OSes won't see it 
if we don't.

5c72d9c4e0 Print image physical location in registration message. 2007-01-12 16:20:51 +00:00

0f29e0e46e Ensure multiboot modules are in ascending order of memory start 
address, to work around OS bugs.

9952df9b52 Add "dhcp" command 2007-01-12 09:53:28 +00:00
Michael Brown
e2c0055e23 Let ifmgmt.c take care of calling efree(), since it's the once which 
took out the contract to eventually call efree() when it called fetch().

Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.
 2007-01-12 09:46:10 +00:00
Michael Brown
39ede8c7e8 Added dhcp() user-level command. 2007-01-12 09:20:11 +00:00

67aedf34fa Use systematic names for XXX_IMAGE. 
Add scripts as an image format (since it's trivial to do).

48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded 
after a call to load().

6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00
Michael Brown
475d6d1f7c fetch() now knows nothing about struct image; it simply loads a file and 
returns the allocated buffer.
 2007-01-12 08:02:27 +00:00
Michael Brown
2876197306 Allow "imgexec" with no arguments to boot the file that was loaded with 
"kernel".
