ROM Support

General Information

In all Old World PowerPC Mac ROMs, the first three megabytes are 68k code, while the last megabyte is PowerPC code. These contain the toolbox as well relevant drivers for particular machines. Code begins executing at 0xFFF00100 upon starting up the computer. By contrast, New World PowerPC Mac ROMs are 1 MB stubs containing basic boot-up code. All Macs supporting PCI also contain OpenFirmware.

No ROMs for non-Mac machines are supported, due to a lack of documentation on these. Moreover, network support has not been implemented as of yet.
