Hi,
I'm back after a period of hard work :)
I tried grub2 on my ppc (apple iBook g3) but I don't
like to change openfw boot-device var every time (I use
the same laptop for my daily stuff) as suggested in
grub wiki.
So written a CHRP script which permit to choose
yaboot or GRUB2, here it is:
-- cut
<CHRP-BOOT>
<COMPATIBLE>
MacRISC MacRISC3 MacRISC4
</COMPATIBLE>
<BOOT-SCRIPT>
: bx-boot-opts 2 ;
: bx-boot-wait d# 100 ; \ unit = 100 ms
: bx-boot-defopt 1 ;
: bx-display-menu ( -- )
." Boot Loaders menu" cr
." 1: yaboot" cr
." 2: GRUB2" cr
;
: bx-boot-choose ( num -- )
case
1 of " /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL
PROTECTED]:2,\\yaboot" endof
2 of " /[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL
PROTECTED]:2,\\grubof.modules" endof
endcase
['] $boot catch drop
user-abort
;
: bx-read-num ( wait-period max-boot-num def-opt -- boot-num )
1 \ loop-inc = 1
3 pick 0 do
0d emit
." press 1-"
( wait-period max-boot-num def-opt loop-inc )
2 pick ascii 0 + emit
dup 1 = if
." within "
3 pick i - d# 10 / .d
." seconds"
then
." (default: "
over ascii 0 + emit
." ) : "
d# 100 ms
key? if
key
( wait-period max-boot-num def-opt loop-inc key )
dup 0d = if \ return pressed
drop leave
then
ascii 0 -
( wait-period max-boot-num def-opt loop-inc num )
dup 0 5 pick
( wait-period max-boot-num def-opt loop-inc num num 0 max-boot-num )
between if
rot drop swap leave
then
( wait-period max-boot-num def-opt loop-inc num )
2drop 0 \ loop-inc = 0
then
dup +loop
drop
( wait-period max-boot-num boot-num )
nip nip
;
load-base release-load-area
stdout @ 0 = if
false to _normal-boot install-console
then
true to use-console? false to ignore-output?
dev /multiboot
flash-dev-icon-off
device-end
erase-screen
bx-display-menu
bx-boot-wait bx-boot-opts bx-boot-defopt bx-read-num
bx-boot-choose
</BOOT-SCRIPT>
</CHRP-BOOT>
-- cut
using hfs tools, overwrite this (after fix it with
your disk real path) on ofboot.b installed by
yaboot (use 'hcopy -r' and 'hattrib' to fix attributes),
reboot and a boot loader chooser will be displayed.
An example :
hmount /dev/<hfs partition"
hrcopy -r myofboot.b :ofboot.b
hrcopy -r grubof.modules :grubof.modules
hrcopy -r grub.cfg :grub.cfg
hattrib -t tbxi -c UNIX :ofboot.b
hattrib -t boot -c UNIX :grubof.modules
hattrib -t conf -c UNIX :grub.cfg
hattrib -b :
humount
This works for me, let me know if something wrong on your
hosts.
If someone isn't already doing, I'm going to write a reiserfs
module (let me know).
Also what about multiboot specification support in grub2?
Is available (on ppc and ia32)? If not why ? :)
thanks,
