[PATCH v2 0/5] Mac OS 9 compatibility improvements
by Cormac O'Brien Aug. 26, 2015

Aug. 26, 2015

This patchset significantly improves OpenBIOS's ability to boot OS 9, adding ESCC legacy ports, reworking ADB interaction with QEMU and fixing IDE controller interaction with the OS. Note that the patch to interpreter.fs is a temporary measure pending a fix that Mark is writing, and that RTAS must be disabled for the OS to boot. Signed-off-by: Cormac O'Brien <cormac(a)c-obrien.org> --- Changes from v1: * Initialize ESCC legacy ports * Don't enable non-implemented DBDMA interrupts * Update some commit messages and comments Cormac O'Brien (5): interpreter.fs: allow evaluate to split words on CR as well as LF ppc: fix up power-mgt properties ppc: add ESCC legacy support ppc: fix CUDA ADB packet header format ppc: fix up IDE device tree and control transfer arch/ppc/qemu/methods.c | 2 + drivers/cuda.c | 17 ++++++-- drivers/escc.c | 88 ++++++++++++++++++++++++++++++++++-------- drivers/escc.h | 2 + drivers/ide.c | 34 ++++++++++++++-- drivers/pci.c | 6 +++ forth/bootstrap/interpreter.fs | 2 +- 7 files changed, 126 insertions(+), 25 deletions(-) -- 2.5.0

If you have tested Cormac's patches, do you see Mac OS 9 booting? I followed all the directions from his testing page and couldn't see anything that belongs to Mac OS 9.

I guess something is different with the Mac OS X build process that prevents Mac OS 9 from working.

I am building on Mac OS X, so that could be the problem. Cormac, the testing page needs minor changes. The line where configure is set, please change the path from "$HOME/os9/qemu-install" to "$HOME/os9-test/qemu-install". The "-test" part is missing. After the "Run QEMU with the following command:" text, please remove the "cd ..". That would take the user into the home folder rather than in the os9-test folder. The command that runs QEMU should be free of any '>' characters. They cause files to be made called -bios, -boot, -ccdrom, -M, and -m. It would probably be easier to copy and paste the command if it were on one line. At the top of the page it talks about having Python 2 installed. The rest of the directions make no mention of using Python. Are you sure it is needed? Other than the minor issues, the web site looks good. Thank you.
