i just found by a google search some old internal apple documentation about the OF ROM of the blue&white powermac G3
...it defines "MacOS-X" as: UNIX-based MacOS; think of it as "Mac OS NT".
it also mentions putting the macio MMIO physical address at 0x80800000 "to boot NT just in case" haha
it also mentions that OF's little endian mode "actually works in OF"
looking at the disassembly of the B&W's init code i have, it actually should work!
basically, when little-endian is set, after setting MSR[LE] it will set bit 5 (LE_MODE bit, turns on little endian) to PICR1, by using CONFIG_ADDR/CONFIG_DATA writes, and only uses every second instruction to do that (with each other instruction being a nop mainly) because of how MSR_LE works
in fact it seems the bootrom of every ppc mac after this has the exact same code, even those that use a different memory controller, no WONDER little-endian? is notorious for bricking lol
If your vendor has security issues and your executives care they can like… demand a meeting. Which is so executive-coded it works.
We did this to a vendor recently and got a groveling layout of internal strategy.
To be Executive you gotta act Executive. Executive decisions. Bam.
Here's the deal: Apple sucks. Samsung sucks. Google sucks. Nokia sucks. Microsoft sucks. All of them fucking suck. Just buy a damn phone/tablet and shut up about it.
and any HP system where its custom protection against performing db/dbx updates is enabled
also:
the file doesn't exist right now, but there's code (behind a registry(?) flag) to apply "dbxupdate2024.bin", and debug strings imply that would revoke the PCA 2011 cert entirely!(GetSecureBootUpdateFilePathPCA2011RevokeDBX)
i expected that to be done, but only on new systems, fun (given that it's behind a flag it may well happen only on new systems)
@wolf480pl IF older systems get the cert revoked it should be able to be reverted in the uefi firmware setup, which has an option to revert db/dbx back to the default (in the uefi firmware)
I don't even understand why the fuck windows update even has error codes when every single fucking one of them always has the same advice from microsoft: Delete SoftwareDistribution, run the troublshooter which never works, run dism /cleanupimage /restorehealth or use the windows 11 installer tool to do a clean install. Don't even bother giving me the error code.
Then you go to the event viewer for windows update logs and its like "the update failed to download" and you ponder the pros of lobotomy via soup spoon.
throwback to when i was like 7 and trying to make my own font by literally drawing the letters in mspaint in the same way the windows xp font viewer did and then naming the file with a .ttf extension and being confused when it didnt work
