Intel Mac Mini elilo walk through

Instructions for building elilo with VGA support, and some other misc patches to fix ext2 handling, set the mac to always power up after a power cut, and to switch to text mode.

NB: many people seem to have trouble with GNU-EFI, if your elilo doesn't work try a different machine. I've had success with CentOS-4.1 running on ia32.
Download and unpack elilo:

Configure and build elilo:
edit the Make.defaults file and set:

CONFIG_ext2fs to y
EFILIB, GNUEFILIB, EFIINC and EFICRT0 to the path where gnu-efi is installed

Then build it:

[root@server elilo]# make
make -C fs
make[1]: Entering directory `/home/root/projects/macmini/walkthrough/elilo/fs'
/usr/bin/gcc -I. -I/home/root/projects/macmini/walkthrough/elilo/fs/.. -I/software/include/efi -I/software/include/efi/ia32 -I/software/include/efi/protocol -O2  -fpic -fshort-wchar -Wall -DENABLE_MACHINE_SPECIFIC_NETCONFIG -DCONFIG_LOCALFS -DCONFIG_NETFS -DCONFIG_CHOOSER_SIMPLE -DCONFIG_CHOOSER_TEXTMENU -DCONFIG_ia32  -c localfs.c -o localfs.o

           -j .rela -j .reloc --target=efi-app-ia32 elilo.so elilo.efi
[root@server elilo]#

You should now have an elilo.efi file, if this was all a bit much you can get a pre-built one.
