1File overview:
2
3grubload/
4 A multiboot-compliant simple ELF loader, for use with NetWatch aseg.elf
5 images or similar. It loads its input file (passed via multiboot),
6 invokes the startup routines, and then returns to real mode and starts the
7 bootloader again.
8
9ich2/
10 Intel ICH2 northbridge/southbridge drivers. A similar API should be
11 implemented to port NetWatch to other chipsets.
12
13ich7/
14 Intel ICH7 northbridge drivers. Incomplete.
15
16include/
17 General header files.
18
19lib/
20 Library functions.
21
22lwip/
23 LWIP. (http://www.sics.se/~adam/lwip/)
24
25net/
26 Network card (currently only 3c90x) drivers, glue code, and the RFB and
27 HTTP applications. Other network drivers and applications should go here.
28
29netwatch/
30 Main startup and initialization code, logging, SMI response, VGA text
31 overlay, and other general top-level sources. To build the main NetWatch
32 binary, run "make" here to produce aseg.elf.
33
34pci/
35 PCI bus interface and BAR-clobbering routines.
36
37tools/
38 Assorted useful Linux command line tools we've found useful, such as for
39 SMRAM segment manipulation, raw I/O port pokes, etc. These are not
40 required to use NetWatch.
41
42video/
43 Framebuffer drivers for VGA text and TNT2 graphics consoles. Supporting
44 graphics on other chipsets will require writing a driver similar to that
45 in tnt2.c.

49Porting NetWatch to other systems will likely require:
50 - A network driver, if you don't have a 3c905 (net/3c90x.c)
51 - A video driver, if you are interested in graphics rather than VGA text,
52 and don't have an NVidia TNT2. (video/tnt2.c)
53 - North- and southbridge drivers for your chipset. (ich2/)

55We have found that Intel generally provides easily-accessible chipset
56datasheets on their website; searching for a particular ICH series part on
57Google will likely lead to the correct datasheet without too much trouble.
58Other chipset manufacturers have been found to be significantly less
59cooperative.
