Heeeeyy... Thats rude... Comparing me to them...
Hey, that wasn’t me. I only compared SkyCapt to rabidz7.
At least I didn’t drag asaggynoodle into it.
I was serious when I mentioned your work with trying to get the Apollo 8/MPC7448 to work as well as trying to map out where the 2GB RAM cap on the DLSDs is holding things back.
The answer is it will halt on unknown CPU and i cant find any patcher that works on that damn DLSD... If i manage to remove that halt on unknown CPU than my DLSD will get a 7448 transplant. Maybe i should start looking into patchers and bootrom and figure out how they work and what and how they modify the bootrom and then maybe making my own patch.
I was going to ask about the bootrom patch the
DayStar upgrade used back in 2006, but then realized they were still using an Apollo 7/MPC7447 chip for that service.
The Sonnet ZIF upgrades for the Power Mac G4/G4 Cube may be another place to look into, but I imagine you’ve already been down that path, as those probably relied on earlier logic board architectures.
EDITING TO ADD:
I stand corrected: DayStar did in fact
offer a 7448 upgrade specifically for the DLSD PowerBooks, and Newer Technology offered a
7448 card upgrade for older desktop G4s. So this means finding the patch DayStar used to make their aftermarket upgrade possible might be the next logical path to look into.
It is likely a really long shot at this point, but maybe try some sleuthing to track down a former engineer at DayStar on LinkedIn or similar, who might be able to talk about or at least direct you toward someone who worked on the old DLSD upgrade service to find out what kind of patching was involved. To my knowledge, DayStar has been defunct for several years and old non-disclosures by former involved staff I imagine are probably null and void now.
