- prep machine is a fictional machine, so has no specifications. Which devices can be changed/added/removed without impact? Are interrupts correctly mapped? - prep firmware (OHW) has support only for IDE drives (no SCSI). Booting from IDE has been broken approximatively 3 years ago, and nobody complained. - OHW is limited on IDE boot to a specific set of OS loaders. These operating systems are of the 2004 time frame. - OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse detection, and then screen becomes garbage. This was already broken in QEMU v2.7, 2 years ago, and nobody complained. On the other side: - 40p is a real machine, so emulation can be checked against hardware specifications - OpenBIOS has support for SCSI block devices, including 40p LSI adapter - OpenBIOS can start mostly all Linux kernels (including recent ones) and recent operating system (like NetBSD 7.1.2) Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> --- hw/ppc/prep.c | 1 + 1 file changed, 1 insertion(+)
