Compilation
|
||
|
|
===========
|
||
|
|
|
||
|
|
IMPORTANT
|
||
|
|
---------
|
||
|
|
|
||
|
|
Don't forget to run 'make clean' before 'make' after you have modified
|
||
|
|
any source or header file(s).
|
||
|
|
|
||
|
|
|
||
|
|
On a x86 host where grub is correctly installed
|
||
|
|
-----------------------------------------------
|
||
|
|
|
||
|
|
Simply run 'make'
|
||
|
|
|
||
|
|
|
||
|
|
On a non-x86 host (without grub of course !)
|
||
|
|
--------------------------------------------
|
||
|
|
|
||
|
|
See extra/README
|
||
|
|
|
||
|
|
|
||
|
|
On an x86 host without Grub, or with a buggy Grub
|
||
|
|
-------------------------------------------------
|
||
|
|
|

See extra/README

How do I know I have a buggy grub installation ? Answer: in the qemu
|
||
|
|
PC emulator, Grub hangs while loading the kernel

Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
Nothing special to do besides compiling
|
||
|
|
|
||
|
|
|
||
|
|
Test the SOS Kernel
|
||
|
|
===================
|
||
|
|
|
||
|
|
On a x86 real machine with Grub installed
|
||
|
|
-----------------------------------------
|
||
|
|
|
||
|
|
1st method
|
||
|
|
=> Boot the sos.elf file (append 'kernel=<path_to>sos.elf' in the
|
||
|
|
menu.lst or type it on Grub's command line) from a hard disk, a
|
||
|
|
floppy, or from the network
|
||
|
|
|
||
|
|
2nd method
|
||
|
|
=> Copy the file 'fd.img' to a floppy and boot from it
|
||
|
|
|
||
|
|
|
||
|
|
On a x86 real machine without Grub installed
|
||
|
|
--------------------------------------------
|
||
|
|
|
||
|
|
1st method
|
||
|
|
=> see extra/README to compile with the grub floppy image we provide,
|
||
|
|
copy the file 'fd.img' to a floppy, and boot from it
|
||
|
|
|
||
|
|
2nd method
|
||
|
|
=> see extra/README to compile with the boot sector we provide (up to
|
||
|
|
article 2 only), copy the file 'extra/sos_bsect.img' to a floppy,
|
||
|
|
and boot from it
|
||
|
|
|
||
|
|
|
||
|
|
Inside a PC emulator (x86 and non-x86 hosts)
|
||
|
|
--------------------------------------------
|
||
|
|
|
||
|
|
Tested on both the bochs emulator (x86/linux, sparc/solaris and
|
||
|
|
ppc/linux hosts, 'apt-get install bochs-x vgabios' on debian
|
||
|
|
testing/unstable), and the qemu system emulator (with libsdl
|
||
|
|
installed: 'apt-get install libsdl1.2-dev' on debian
|
||
|
|
testing/unstable).
|
||
|
|
|
||
|
|
1/ Grub is installed on the host (x86 hosts only)
|
||
|
|
- - - - - - - - - - - - - - - - - - - - - - - - -
|
||
|
|
|
||
|
|
bochs: boot from the file 'fd.img'. Example of a ~/.bochsrc:
|
||
|
|
floppya: 1_44=/home/d2/sos/fd.img, status=inserted
|
||
|
|
romimage: file=/usr/share/bochs/BIOS-bochs-latest, address=0xf0000
|
||
|
|
vgaromimage: /usr/share/vgabios/vgabios.bin
|
||
|
|
megs:63 # 63 Mo de RAM
|
||
|
|
|
||
|
|
qemu: run 'qemu -fda fd.img'
|
||
|
|
If grub hangs while loading the kernel, please go to method 2/
|
||
|
|
|
||
|
|
2/ Grub is not installed (all hosts)
|

|
|
|

|
|
See extra/README to generate a floppy image with the Grub floppy
|
||
|
|
image we provide, and:
|
||
|
|
|
||
|
|
bochs: boot from the file 'fd.img'
|
||
|
|
|
||
|
|
qemu: run 'qemu -fda fd.img'
|
||
|
|
|
||
|
|
3/ Bonus: boot with the bootsector we provide (all hosts, up to art. 2 ONLY !)

bochs: boot from the file 'extra/sos_bsect.img'
|

qemu: run 'qemu -fda extra/sos_qemu.img'
