This file explains how to install EMILE to boot from a SCSI disk.
|
|
|
|
first of all:
|
|
|
|
USE WITH CAUTION AND AT YOUR OWN RISKS !!!!!
|
|
|
|
This operations will modify properties of your partition map (if you haven't got HFS partition) or the bootblock of your HFS partition (if exists)
|
|
|
|
If you generate binaries from sources packages, you must:
|
|
|
|
# cp emile/tools/emile /sbin
|
|
# mkdir /boot/emile
|
|
# cp first/first_scsi /boot/emile
|
|
# cp second/second_scsi /boot/emile
|
|
|
|
The first operation to do is to show the state of your partition map:
|
|
|
|
emile2:~# emile --scanbus -v
|
|
/dev/sda: block size: 512, blocks number: 528808 (258.207 MB)
|
|
Drivers
|
|
0: base: 64 size: 19 type: 1 <2: Macintosh [Apple_Driver43]>
|
|
Partitions
|
|
/dev/sda1 : Apple [Apple_partition_map]
|
|
base: 1, count: 63 (31.500 kB)
|
|
flags: 0x00000037
|
|
/dev/sda2 : Macintosh [Apple_Driver43 ] *
|
|
base: 64, count: 32 (16.000 kB)
|
|
flags: 0x0000007f
|
|
/dev/sda3 : A/UX Root [Apple_UNIX_SVR2 ]
|
|
base: 182864, count: 345944 (168.917 MB)
|
|
flags: 0x00000037
|
|
/dev/sda4 : Swap [Apple_UNIX_SVR2 ]
|
|
base: 150096, count: 32768 (16.000 MB)
|
|
flags: 0x00000037
|
|
/dev/sda5 : MacOS [Apple_HFS ] <Apple bootblock>
|
|
base: 96, count: 150000 (73.242 MB)
|
|
flags: 0x000000b7
|
|
|
|
The aim of the operation is to install the EMILE bootblock on the first HFS
|
|
partition of the disk and to set information in it to find the second level
|
|
boot block. Then with set information in second level to find the kernel. All
|
|
is done automtically by emile.
|
|
|
|
But you need a kernel... you can use the one provided with your Debian after a little modification: move it from ELF format to binary format.
|
|
|
|
# cd /boot
|
|
# gzip -d -c vmlinuz-2.2.20-mac > vmlinux-2.2.20.tmp
|
|
# objcopy -I elf32-big -O binary -R .note -R .comment \
|
|
-S vmlinux-2.2.20.tmp vmlinux-2.2.20
|
|
# rm vmlinux-2.2.20.tmp
|
|
|
|
You can compress if with gzip if you want, but you have enough space on your
|
|
disk, let it uncompressed: the boot sequence will be faster.
|
|
|
|
Now, we have a kernel, we can install EMILE !
|
|
|
|
You can test operation without modifying anything with parameter "--test".
|
|
|
|
emile2:~# emile --test --kernel /boot/vmlinux-2.2.20
|
|
ERROR: there is already a bootblock on "/dev/sda5"
|
|
you must use "--backup" to save it
|
|
partition: /dev/sda5
|
|
first: /boot/emile/first_scsi
|
|
second: /boot/emile/second_scsi
|
|
kernel: /boot/vmlinux-2.2.20
|
|
append: root=/dev/sda3
|
|
buffer size: 0
|
|
|
|
As we try to avoid to lost the Apple bootblock, EMILE check it and did nothing
|
|
if you don't explicitly backup it.
|
|
|
|
Now, we can really install EMILE:
|
|
|
|
emile2:~# emile --kernel /boot/vmlinux-2.2.20 --backup
|
|
Bootblock backup successfully done.
|
|
partition: /dev/sda5
|
|
first: /boot/emile/first_scsi
|
|
second: /boot/emile/second_scsi
|
|
kernel: /boot/vmlinux-2.2.20
|
|
append: root=/dev/sda3
|
|
buffer size: 0

|
|
|
|
Note: by default, EMILE installs bootblock on first HFS partition, and set
|
|
"root=" to the partition where is stored second_level.
|
|
|
|
You can specify all parameters, see emile usage:
|
|
|
|
emile2:~# emile --help
|
|
Usage: emile [OPTION]
|
|
Update and install EMILE stuff on your SCSI disk.
|
|
EMILE allows to boot linux directly from linux partition
|
|
-h, --help display this text
|
|
-v, --verbose active verbose mode
|
|
-t, --test active test mode (don't write to disk)
|
|
--scanbus display information about all disks and partitions
|
|
-f, --first PATH set path of EMILE first level
|
|
-s, --second PATH set path of EMILE second level
|
|
-k, --kernel PATH set path of kernel
|
|
-a, --append ARG set kernel command line
|
|
-p, --partition DEV define device where to install boot block
|
|
--restore[=FILE] save current boot block from FILE
|
|
--backup[=FILE] save current boot block to FILE
|
|
--set-hfs set type of partition DEV to Apple_HFS (needed to be bootable)
|
|
|
|
If you want to boot MacOS again (sure ?), you must restore the Apple bootblock
|
|
with:
|
|
|
|
emile2:~# emile --restore
|
|
Bootblock restore successfully done.
|
|
|
|
"--backup" saves by default bootblock in "/boot/emile/bootblock.backup"
|
|
|
|
But remember, to be bootable, a disk must have:
|
|
- a partition map
|
|
- an Apple_Driver partition
|
|
- an Apple_HFS partition
|
|
- a bootblock on Apple_HFS
|
|
|
|
EMILE cannot create an Apple_Driver partition, so you must partition before
|
|
all your disk with the Apple Disk Utility.
|
|
If you don't want to have MacOS on your disk, EMILE can change the linux root
|
|
partition to HFS... and all works fine ;-)
|
|
|
|
And now, you can start linux in less than 2 seconds...
