I’m not sure with the 7448, it was used it some upgrades for Powermac G4’s from third parties. I’ll have to check what OS’s there where compatible with. I think it’s just a 7447a with double the L2 cache. Compatible OS Versions:: Mac OS 9.2.2 or Mac OS X 10.3.5 (oor later)) is required for all models.. Mac OS X 10.3.8 or later is recommended.. This package contains:: • Newer Technology MAXPower G4 upgrade card,, heat sink with fan and power connector • CD--RROM with manual and frmware installation • A magnetized Phillips screwdriver Firmware Update:: IMPORTANT:: This upgrade REQUIRES the Newer Technology 7447A//77448 Firmware Update provided on CD or it WILL NOT WORK.. https://eshop.macsales.com/tech_center/manuals/newertech/maxpower/nwtmang4max.pdf So I wondering if someone used an old firmware as the reference in qemu-ppc when support for booting OS X was added. Maybe there is some magic we need to boot from the 7450/7455/7447a/7448. I was able to boot a custom kernel that someone had added 604 support for Tiger( 10.4.8 ), with the 7448 in qemu-ppc.
