MacOSX 10.4.11

[d.de...@gmail.com]

I have an old PowerMac G4 (Mirror drive) with scsi card on which I would like to use an old Exabyte 8505 tape reader (rebranded by SUN). 

I tried to make a new xcode project on this G4 (XCode 3). Compilation went fine for both the dd command and the driver extension. 

However, the extension seems to be ineffective. 

Would it be possible to get a 10.4 binary version of ioscsitape?

Alternatively, does someone may explain me if it is possible to set a scsi interface on a MacBook Pro or on an iMac 2012?

how did you do the installation?  kexts aren't the kind of thing you just drop into the /System/Library/Extensions folder and have them run.  If you got it to compile. you should be in good shape, try googling around for "installing kext"

It isn't that hard. I did it myself and I didn't even crack a web howto open! of course. I did browse the man pages to learn of kextload which loads kernel modules
if you type
kextload -t IOSCSITape.kext it will tell you that you need to chown the files to root:wheel. which is easily done like so

chown -Rv root:wheel IOSCSTape.kext
# the -v allows me to verify that it is doing the right thing

i then, for testing, type
kextload -t IOSCSITape.kext
if it loads with no errors. then I make a tar and move it to /System/Library/Extensions like so
for this , you need to have sudo /bin/bash, which you needed to chown anyway so not a problem

tar xvf IOSCSITape.tar

and all is cool. Kinda of similar to insmod {module name} on Linux or modprobe {module name}

there is also an kextunload command as well! look it up in man!

I am more familiar with the command line. not sure what GUI tool does the same work.

I forgot a very important step! you need to make your tar first ;) so from the ioscsitape/build/Debug directory type
tar cvf IOSCSITape.tar IOSCSITape.kext

then you have the tar file to extract.
