http://www.oldschooldaw.com/forums/index.php?topic=154.0http://archive.digidesign.com/compato/http://archive.digidesign.com/support/compat/your problem is most likely related to the order in which the extensions are loading
you need to rename the digi init extension which checks the card is installed +working while booting up
to have a first letter higher up in the alphabet
see this thread for discussion on the topic of altering extension loading order
http://macos9lives.com/smforum/index.php?topic=1728.0take this next bit with a grain of salt: (or take it very seriously,
because digidesign apps are VERY partifcular about which EXACT version of OS they are RUN ON).
ie: pro tools Le 5.0 is onyl for 9.0 + under, whereas pt le 5.1 is for 9.1+
(did u catch that? maybe read that line agan a few times to let it sink in)
the "pro tools free" version is only officially supported on os9.0 (not 9.1)
i wouldnt be surprised if doing a restore/install for your specific machine will miraculously solve your problem
(that is, mac os 9.02 which is specifically for the 400/450mhz g4 "Sawtooth" machines
see this thread for more on that:
http://macos9lives.com/smforum/index.php?topic=1737.0i went out of my way to locate those original discs and make them available for download from my private mediafire account to help people such as yourself
my advice would be to get a fresh disk and burn the official restore cds for the sawtooth model that you own, remove all hardware except 1 video card + the AMIII and do a system restore using the cd to a freshly formatted HD, and be amazed when it "just works"
also unplug all these "OLD" hard drives..
u dont need these 15gb drives..
just use the one 120gb and one other disk for a scratch disk for pro tools
you may have an easier time of installing osx Panther 10.3.9 and pro tools 6.x
but os9 will be alot faster on that g4/400
anyway.goodluck
the answers are here if u choose to listen
i personally dont have an amIII card or otherwise i would provide more specific detailed instructions
maybe someone else who has one up + running can share their installer files with you
