10.5: Install on a PPC Mac from an external USB Drive - extra devaliases
Authored by: hfelton on Apr 23, '13 06:58:48AM
howdee - im a new user, but registered for just this one long/detailed comment/reply...

0 - THANK YOU to all who came before on this hint/thread/comment... i am just standing on top of the giants before and adding my little comments for others...


1 - i could not make a windows-keyboard work... in particular, my imac (g5) would 'ask' about it when powering up by having me press the key 'just inside of shift key' on each side... thus, i was never able to make the keyboard-combo work correctly... if you cannot get into open-firmware, then try getting a normal MAC-keyboard...


2 - i was having all sorts of problems trying to get the correct device to use for the 'dir' command... i could see the tree of information, but could never make a working 'devalias' for myself... two clues:

  • a - if (when you type devalias xx yyy@yy\yy\yy\yy) you receive a comment 'no alias' in response, then it did NOT work... you should see a 'good' response of just the word OK... even so, i was never able to 'use' my own devalias...
  • b - i noticed in one of the later-comments someone had tried just typing the word 'devalias' without anything else... when i typed that, i got a nice long list of predefined aliases... in particular, i could see one called 'first-boot' that looked like it should access my working tiger-hdd internally... also, if i just typed 'boot' it would do what youd expect [boot from the first-boot device, which is the current internal hdd]...


    3 - i was finally able to get things working better by doing/trying the following (details removed for hopeful-clarity):

  • dir first-boot/@0:3,\
    - and i finally saw something good... nb, i needed the exact-extra-characters listed [7 chars starting with / and ending with \] to get a 'good' dir... and i assume others will have the devalias of 'first-boot' predefined like i did...
  • dir usb0/@1:3,\
    - was the magic incantation i used for getting to my external-usb-key [8gb formatted/dmg-restored as needed]... in particular, the '1:3' here on usb0 and the '0:3' with first-boot matched the disk:partition information i got when i looked at the key using the regular get-info command from tigers disk-utility...
  • i could do a more-detailed 'dir' on the key until i got to the ...\CoreServices directory level... i could NOT actually do a 'dir' on the BootX file itself... but the CoreServices directory showed the 'magic' tbxi flag on that BootX file that i expected to see...
  • i could use the 'UP-ARROW' to repeat the last command that id typed, so that i could just change the 'dir' to a 'boot' and add the BootX to the end and it would work... (using left- and right-arrows to leave the other good characters in place)


    4 - once i got my magic incantation correct, it took prolly an hour to get thru the first-boot - but eventually i got the great happy-mac sound from the other room... hopefully you will be able to too... :)


    repeating: for me, the exact command i used was
    boot usb0/@1:3,\System\Library\CoreServices\BootX
    ... gl & hth, h.
