Hi Gentoo foolks, |
| 2 |
|
| 3 |
Now that 2005.0 is out I think we should try to provide |
| 4 |
some infos for installing Gentoo on external firewire disk |
| 5 |
to Gentoo PPC users (the question pops up frequently in |
| 6 |
the web forums) |
| 7 |
|
| 8 |
I've been done it in the past (using 2004.0 or 2004.1 |
| 9 |
I can't remember). |
| 10 |
|
| 11 |
I've been doing the work again on a second ibook this time |
| 12 |
using 2005.0 (with use of udev but not bootsplash) and |
| 13 |
with most stuff compiled (instead of use of modules). |
| 14 |
I can do it again if this can help to serve as testing |
| 15 |
and help getting the handbook updated. |
| 16 |
|
| 17 |
Clearly I didn't use genkernel. |
| 18 |
I've never used genkernel in the past. Do you recommend |
| 19 |
using it ? |
| 20 |
|
| 21 |
I've been installing 2005.0 on an ibook 900Mhz G3 |
| 22 |
using G3 dofirewire as parameters. |
| 23 |
I did create some partitions on an external firewire |
| 24 |
disk (Oxford 911 controler). |
| 25 |
|
| 26 |
Information needed to be added to the handbook for |
| 27 |
installation on external firewire disk is : |
| 28 |
|
| 29 |
1/ special yaboot.conf parameters required |
| 30 |
2/ .config entries needed |
| 31 |
3/ creation of an initrd |
| 32 |
|
| 33 |
|
| 34 |
1/ ofboot, boot, device must be defined properly. |
| 35 |
An image= entry with initrd must be created . |
| 36 |
|
| 37 |
|
| 38 |
Example : |
| 39 |
mac-fdisk -l /dev/sda |
| 40 |
/dev/sda |
| 41 |
# type name length base ( size ) system |
| 42 |
/dev/sda1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map |
| 43 |
/dev/sda2 Apple_Driver43 Macintosh 56 @ 64 ( 28.0k) Driver 4.3 |
| 44 |
/dev/sda3 Apple_Driver43 Macintosh 56 @ 120 ( 28.0k) Driver 4.3 |
| 45 |
/dev/sda4 Apple_Driver_ATA Macintosh 56 @ 176 ( 28.0k) Unknown |
| 46 |
/dev/sda5 Apple_Driver_ATA Macintosh 56 @ 232 ( 28.0k) Unknown |
| 47 |
/dev/sda6 Apple_FWDriver Macintosh 512 @ 288 (256.0k) Unknown |
| 48 |
/dev/sda7 Apple_Driver_IOKit Macintosh 512 @ 800 (256.0k) Unknown |
| 49 |
/dev/sda8 Apple_Patches Patch Partition 512 @ 1312 (256.0k) Unknown |
| 50 |
/dev/sda9 Apple_Bootstrap bootstrap 1600 @ 1824 (800.0k) NewWorld bootblock |
| 51 |
/dev/sda10 Apple_UNIX_SVR2 swap 1048576 @ 3424 (512.0M) Linux swap |
| 52 |
/dev/sda11 Apple_UNIX_SVR2 root 83886080 @ 1052000 ( 40.0G) Linux native |
| 53 |
/dev/sda12 Apple_Free Extra 313359008 @ 84938080 (149.4G) Free space |
| 54 |
|
| 55 |
Block size=512, Number of Blocks=398297088 |
| 56 |
DeviceType=0x0, DeviceId=0x0 |
| 57 |
Drivers- |
| 58 |
1: @ 64 for 23, type=0x1 |
| 59 |
2: @ 120 for 36, type=0xffff |
| 60 |
3: @ 176 for 21, type=0x701 |
| 61 |
4: @ 232 for 34, type=0xf8ff |
| 62 |
|
| 63 |
Run : |
| 64 |
find /proc/device-tree -name disk@* | grep firewire |
| 65 |
/proc/device-tree/pci@f4000000/firewire@e/node@0001d200e00d0207/sbp-2@c000/disk@0 |
| 66 |
|
| 67 |
If there is no output from the find command try to reboot and make another try |
| 68 |
(some times it seem to occur). |
| 69 |
|
| 70 |
In such a case the yaboot.conf must then must include : |
| 71 |
ofboot=fw/node/sbp-2/disk@0: |
| 72 |
# Apple_Bootstrap bootstrap partition |
| 73 |
boot=/dev/sda9 |
| 74 |
# Real device name (can be obtained from OpenBoot) |
| 75 |
device=fw/node@0001d200e00d0207/sbp-2@c000/disk@0: |
| 76 |
|
| 77 |
2/ as mentioned I did not use modules in the past. |
| 78 |
I'm thinking about mentionning : |
| 79 |
CONFIG_BLK_DEV_INITRD=y |
| 80 |
CONFIG_IEEE1394_OHCI1394=y |
| 81 |
CONFIG_USB_ARCH_HAS_OHCI=y |
| 82 |
CONFIG_USB_OHCI_HCD=y |
| 83 |
CONFIG_IEEE1394=y |
| 84 |
CONFIG_IEEE1394_OHCI1394=y |
| 85 |
CONFIG_IEEE1394_SBP2=y |
| 86 |
|
| 87 |
|
| 88 |
3/ mkinitrd must be used to create a ramdisk. |
| 89 |
I faced some issues : apparently mkinitrd now create |
| 90 |
a gzipped cpio archive and not a gzipped ext2 content see : |
| 91 |
https://www.redhat.com/archives/fedora-list/2005-January/msg01168.html |
| 92 |
I used an old initrd (ext2.gz format) and it worked. |
| 93 |
Each time I do it I forget to create a /initrd directory (and end up |
| 94 |
with pivot_root fatal errors) |
| 95 |
|
| 96 |
|
| 97 |
Right now using this procedure I can boot on my firewire disk |
| 98 |
I still need to activate bootsplash ... |
| 99 |
|
| 100 |
Do you recommend I retry this installation with genkernel and/or |
| 101 |
activate other stuff ? |
| 102 |
|
| 103 |
I can put .config and linuxrc somewhere. |
| 104 |
|
| 105 |
I hope this information helps .... |
| 106 |
