ahh its still not quite right im afraid
this is what you should do :)
dev /cpus/PowerPC,G4
000c0206 encode-int " cpu-version" property
unselect-dev
and if you want to actually see the changes before and after you would want to do it like so
dev /cpus/PowerPC,G4
.properties
000c0206...
BTW @Phipli I was just reading the page you made for it, and I notice your instructions for spoofing the CPU PVR are not quite correct, please refer to this post I made on MR on how to do it correctly :)...
did you do a .properties check after spoofing the CPU PVR to make sure the changes had indeed gone through?
the checksum error is normal, but I note your trying that on an AlBook, so I think its hanging up on the GPU side of things, most later apple portables and AIO's dont have the GPU's NDRV...
I have a guide I put together here :)

Sweet stuff! glad to see my modified ROM is being put to good use :)
a few things to note:
the MacOS8.6 ROM is quite picky about which Video card it will work with, for best results, use only an ATI Video card with a full ROM (this is why certain machines like Snow iBooks and iMacs fail to...
have you made sure the G4 Cube's firmware itself is full up to date? 4.1.9 is the latest IIRC
I think only later versions of the firmware natively support the 7455, so something worth double checking
Sadly nothing with a Uninorth, I think the oldest schematic I ever found was for a GigE TiBook and that is a 7450 based machine sadly
although that being said I think I do have schematics for a later iBook G3 if thats any use? but thats 750FX machine IIRC
yeah I was just catching up on the...
ok thats seriously Awesome! the whole 60x vs MPX bus mode thing is something I have been wondering since I did my very first Pismo upgrade in December 2016!
at first I did wonder if it would switch over automaticly, but later on studying schematics for PowerBook G4's etc, showed there where...
in my experiance the 500Mhz G4 7410 Sonnet ZIF has 3 settings Max-multiplier-9X mode if FSB is less than 66Mhz, if 66Mhz then 7.5 and if more than 66Mhz it goes into 5x mode for 100Mhz expected FSB operation...
ooh yeah id be very interested in seeing an interposer developed!
I know there is someone on here who has made a 7450-7455 BGA483 to BGA360 interposer to retrofit 7447A's and 7448's to existing DA/QS/MDD cards
but it would be awesome to see such an interposer for all the other PPC CPU's...
Oh wow thats amazing! hopefully you can get the remaining niggles sorted before not too long and get it booting :)
its actually a really good thing you added those PLL dip-switches
because the achilles heel of the PowerLogix 750FX and 750GX CPUs is their base multiplier is only set to about...
in theory you should be able to boot OS X directly on an ANS without any need to swap ROMs since the ANS does run OpenFirmware
as OS X bypasses any need for a Toolbox ROM image and boots directly from OpenFirmware including on OWR macs
the only things you would need to do is figure out what...
one thing ill punt out there to keep in mind
is that if you install OS 9 on a mac without a USB card installed, then by default it wont install USB drivers, so installing a PCI USB card after install time wont work OOB on any old world Mac
I found this out the hard way back in the day when I...
its very awesome to see the home made LCIII board is finally working/booting :)
it really has been awesome to see all the reverse engineering going on here, some proper hard work by some very skilled people!
I look forward to further progress and seeing what else gets done in the future :)
