howdee - im a new user, but registered for just this one long/detailed comment/reply..
a - if (when you type devalias xx yyy@yyyyyyyy) 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]..
- 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..
- 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)
- .UPDATE 28th June 2011. Seems like the problem has been resolved with the new 10.6.8 update. It can take awhile, at least 10 seconds at times.
- You 'hacked' Boot Camp Assistant in order to be able to create a Windows USB drive, and that's right, but the problem is that only Macs that come without a SuperDrive (the MacBook Pro with Retina display, Mid 2011 and newer Macs mini, the Late 2012 iMac and all MacBooks Air) can install Windows through a USB drive because of firmware restrictions.
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:
3 - i was finally able to get things working better by doing/trying the following (details removed for hopeful-clarity):
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 .. gl & hth, h.
