Hi,
I am still trying to boot OS/2 PPC edition with Qemu. Non-contiguos
IO map & no support for Little-endian have been solved now thanks to J.
Mayer who sent me patches to work these out. Now bootloader gives me
following message:
IBM Microkernel bootloader press enter for manual boot(enter)
and I have following boot options to choose from:
cdrom
hd
if I try to use either one of these Qemu gives me
outl: port= 0x0cf8 data=0x80006000
inl: port= 0x0cfc
(Bootloader continues with)
Invalid PCI configuration
Device initializion failed
Any ideas why is this?
There are two problems here:
first, the PREP PCI controller does not map its legacy ISA IO ports.
This is a bug.
But fixing this point is not sufficient to make the loader happy:
it tries to access the PCI device 0x60 (96) which does not exists. Then,
I think the lack of devices description in Open Hack'Ware residual data
can be a good suspect for this. Or it can be that real PREP machine
always have the IDE (or SCSI !) controller mapped as PCI device 0x60,
but I'm very suspicious about this.
