OpenBSD/MACHINE OSREV runs on iMac, G4 Power Macintosh, G4 Cube as well as possibly some other G3 Macintosh systems. Older ADB-based systems will not work, only USB keyboard is supported. Has been tested on iMac Rev A/233MHz and Rev C/333MHz machines, several Power Macintosh G4 systems (single and dual processor), as well as the G4 Cube. Some success has been reported on a PowerBook, however this is not well supported. Some code has been written to work better on the B&W G3, but has never been retested. Hardware availability is currently limiting development on these systems. Supported devices {:-include-:}: IDE hard disk controllers. iMac/G4 onboard supported. SCSI host adapters: Symbios Logic (NCR) 53C8xx-based PCI SCSI host adapters AGP/SVGA/VGA Display Adapters: Primary Openfirmware display only. Serial ports: None.
