What is LBdistro?

LBdistro is an improvement on buildrom to let user customize what binaries will be at final ROM. The original name was biosdistro but Uwe suggest me change it to LBdistro. In the LBdistro the user can just select through menus what applications, kernel features and LinuxBIOS will be added to ROM. So the system will compile everything and the user needs just write this firmware into BIOS flash memory.

How to getting started?

First you need download the toolchain used to compile some LBdistro packages:

wget http://lbdistro.sourceforge.net/tools/toolchain.tar.bz2

Extract it to /usr/local:

sudo tar jxvf toolchain.tar.bz2 -C /usr/local

Get last LBdistro from SVN repository:

svn co https://lbdistro.svn.sourceforge.net/svnroot/lbdistro/trunk LBdistro

After that issue:

cd LBdistro
make menuconfig
make

Move the create file (deploy/emulation-qemu-i386.rom) to your HOME renaming its name to bios.bin

Compile QEMU and apply patches to support 2MB BIOS

Execute QEMU using the argument -L pointing to directory where bios.bin is located (we use ~ to refer to HOME)

qemu -L ~ -hda /dev/null

For now only QEMU compilation is generating ROM, but other boards will be added after Kdrive and application works.

Known problems

The final LinuxBIOS ROM created is not starting correctly in Qemu.

TODO

Remove the needs of external toolchain, the build system needs create the toolchains too.

Add Gigabyte M57SLI-S4 to real tests.
