The Beige G3 SCSI is driven by the AppleMESH driver, which is still in Mac OS X at this point. However, the AppleMESH driver is using the "older" SCSI IOKit superclasses, rather than the newer scheme introduced in Jaguar (I believe). The older scheme still works, but is deprecated and some things might not be working properly. I've been assuming that Apple will rewrite AppleMESH eventually to use the new scheme -- if not, I'll probably do it myself sometime. (I believe there are still some supported Powerbooks with the MESH SCSI hardware).

Is the SCSI bus even supported by Mac OS X on that system to begin with? Basically you are using a system not supported by Mac OS X and unless XPostFacto adds in the needed drivers/support for the internal SCSI controller I doubt things will work.

Do you see the internal SCSI bus in question even listed in the IO registry? You can use the ioreg command line tool or IORegistryExplorer (/Developer/Applications/Utilities/) to look around.

Hi again,

after rebooting into OS 9, Toast gives me the following information about the SCSI burner...

Vendor: TEAC CD-R55S
SCSI Port: Bus 0, ID 4
Firmware version: 1.0H
ISO/ECMA/ANSI version: 0/0/2
Internal Protocol version: n/a
Drive serial number: n/a
Cache size: 1 MB

the question is, how do I go about at the very least getting IOKit to recognise the drive? It seems to be incorrectly polling the SCSI chain or something and so returns nothing.

Any ideas? Thanks...

I've recently compiled (after fixing some errors) and attempted to run the example projects:
1) SCSIOldAndNew
-- old access unsupported with new build system. So I unlinked the non-STUD files and commented out references to the old access apis. 2) AuthoringUnitTest
-- Builds and runs fine - no devices found however.
3) OtherUnitTestUnixTool
-- Builds and runs fine (after importing IOKit.framework) - just no output.

I'm using the following System:
Xcode 1.2, Mac OS X 10.3.4 (& XPostFacto 3.0b1)
Beige G3 233 with built in SCSI, Teac 4x SCSI burner.

I'm hoping to be able to build in support for my device for CD burning, but am not sure where to start as none of these examples actually seem to do anything useful. i.e., none of them show any useful info or find any devices.

Any help in moving forward on this would be much appreciated.
Cheers.
