Yes, but I don't see where Mac OS X has this hardcoded. It gets passed in somehow.

What machine type is this? g3beige? On there, I don't see an ide1 alias anywhere:

 ok

Somehow Mac OS resolves "ide1" into "/pci/mac-io/ide@1000". That's the part where the logic fails.

Please don't drop the CCs. There's a good reason I added Mark and the OpenBIOS list. This issue is very likely completely QEMU unrelated.

I think a kernel extension does it. I don't know which one.

Do you think adding ide1 to the /aliases node will fix things? I guessing ide1 should equal ide0. The problem I see with this plan is the pci-ata node. A real Beige G3 doesn't have one in that path.

Sorry. Will try to keep them intact.

Well, I've tried to grep through the full file system of the 10.2 ISO and don't find anything that would indicate the path above. It has to come from somewhere ...

I think it's worth a try. It looks almost as if ide0 is a misnomer and it really should be ide1 there. Not sure.

How do you enable verbose boot in bootx?

Hrm. My wait message is actually different:

From path: "cd:9,\mach_kernel", Waiting on <dict ID="0"><key>IOPathMatch</key><string ID="1">IODeviceTree:/pci@80000000/@4:9</string></dict>

Seems almost like it's resolving the path wrong for me too. Fun.

Found it out. It's as simple as passing -prom-env 'boot-args=-v' to QEMU :).

I did make a new alias in the /aliases node for a ide1. It unfortunately didn't help boot Mac OS X. Its value was the same as ide0.

Ok. I will try it.

Hold down the command key and v while starting up.

Paths also depend on how you pass boot device:

For example with
-drive file=/path/to/cdrom.iso,media=cdrom,index=0,if=ide

I get
ide0                      "/pci@80000000/mac-io@3/ata-1/cdrom"
cd                        "/pci@80000000/mac-io@3/ata-1/cdrom"
cdrom                     "/pci@80000000/mac-io@3/ata-1/cdrom"
ide1                      "/pci@80000000/pci-ata@4/ata-2/cdrom"

(also now that I look at it should this ide1 even be here?)

and with -cdrom /path/to/cdrom.iso

ide0                      "/pci@80000000/pci-ata@4/ata-2/cdrom"
cdrom                     "/pci@80000000/pci-ata@4/ata-2/cdrom"
cd                        "/pci@80000000/pci-ata@4/ata-2/cdrom"

Thank you sooo much for this information. With it was able to go further than before in the boot process! This day was definitely a step forward in making Mac OS X boot in QEMU. The Mac OS 10.2 cd stopped after the COLOR display text, but the darwin 8 cd was able to boot considerably further than before.

Before I would only see up to this in on the screen: 
IOService:/GossamerPE/pci@80000000/AppleGracklePCI/pci-ata@4/CMD646Root/cdrom@0

After using your command line suggestion, I see this in QEMU when booting Darwin 8 (core of Mac OS X): 
IOService:/GossamerPE/pci@80000000/AppleGracklePCI/mac-io@3/Heathrow/ata-1@20000/HeathrowATA/ATADeviceNub@0/IOATAPIProtocolTransport/IOSCSIPeripheralDevieNub/IOSCSIPeripheralDeviceType05/IODVDServices/IODVDBlockStorageDriver/QEMU QEMU DVD-ROM Media

A lot more than before!

This is what I see on a real Beige G3:
IOService:/GossamerPE/pci@80000000/AppleGracklePCI/mac-io@10/Heathrow/ide@21000/HeathrowATA/ATADeviceNub@0/ATAPIProtocolTransport/IOSCSIPeripheralDeviceNub/IOSCSIPeripheralDeviceType05/IODVDServices/IODVDBlockStorageDriver/HL-DT-ST DVD-RW GCA-4020B Media/IOCDPartitionScheme/Untitled 1@1/IOApplePartititionScheme/Mac_OS_X@9

So what's next is making the IOCDPartitionScheme show up.

This path change definitely needs to be made to QEMU.

If anyone wants to help but don't have Mac OS X, you can download the free Darwin 8 cd image here: darwinppc-801.cdr.gz.

Hmmmm last time I tried I couldn't even get the IOService to match - 
maybe some of the recent IDE fixes in QEMU have got this to work?

Have you had a look at the Darwin source to see how this is actually 
detected?

There seems to have been a lot to this thread over the weekend, however 
am I right in guessing that the primary change is switching the CDROM 
over from the CMD646 IDE bus to the MacIO IDE bus?

Will this actually work? Last I remember from Alex was that the Mac 
device model generated by QEMU would only work with MacOS <= 10.3, and 
the release notes in the same directory indicate that 801 is equivalent 
to the kernel for MacOS 10.4. It's for this reason that I've been using 
darwinppc-602.cdr.gz for all my tests here.

Also Amadeusz, didn't you have some extra patches for -M mac99 Darwin 
boot that still need to be reviewed by Alex?

ATB,

Mark.

Probably the BSY flag fix

probably this one:

OSDictionary * IODiskMatching( const char * path, char * buf, int maxLen) 
...

// scan the tail of the path for "@unit:partition"
        do {
            // Have to get the full path to the controller - an
    	// alias may
    	        // tell us next to nothing, like "hd:8"
...

It always seemed to work better for me, so I'm in favor of changing
default if possible.
