Re: [OpenBIOS] Fix boot-script parsing for openSUSE ppc media
by laurent＠vivier.eu Feb. 2, 2009

Feb. 2, 2009

>> Fix boot-script parsing for openSUSE ppc media > >applied, thanks I've applied it, as it breaks nothing and allows to use Suse, but a better fix should be: - correctly parse the script to replace &device; by the boot device ("cd:", and not "cd:0", which is "&bootdevice;:&partition;") - correctly manage CD partition to be able to use ":1" instead of ":0" (in fact, for the moment, we use mac partition on CD and ":0" to use the entire disk).

With coreboot-v3 and OpenBIOS SVN then the base address for I/O devices is set to 0x400 which causes subsequent hardware to be mapped higher.

My quick fix was to apply the following patch to openbios in order to raise the io_base further from 0x400 to 0x520 so that no devices appear below the BIOS_IO_PORT address of 0x510: --- drivers/pci.c (revision 428) +++ drivers/pci.c (working copy) @@ -762,7 +762,7 @@ mem_base = arch->mem_base; /* I/O ports under 0x400 are used by devices mapped at fixed location. */ - io_base = arch->io_base + 0x400; + io_base = arch->io_base + 0x520; path = strdup(""); for (bus = 0; bus<0x100; bus++) { ob_scan_pci_bus(bus, &mem_base, &io_base, &path); With this patch applied, I am pleased to report that qemu can successfully boot openbios once again. Can anyone with more knowledge comment on whether this is an adequate solution or not?
