Normally I would consider dependencies on the register allocation a bug in grub, not in the compiler. Not sure what a DOS ddt is? Please give details what I should do. Should LBA changes cause a triple fault? sda1 is an old partition with 10.2 grub that works, the 11.3 is on sda4 and if I switch the bootable flag to that the problem happens.

BIOS calls are to preserve certain registers across calls, which they not always do. Depending on the compiler's register allocation this does or does not matter. ddt was the "dynamic debugging tool" a.k.a. debugger of XX-DOS. If you can boot such a dinosaur, maybe from floppy or CD emulation, you have a chance to watch stage1 run, or single-step until it faults. You have a DOS with debugger around and can tell more precisely where it faults? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But I don't see it including a debugger :( From here my search engine is as good as yours. stage1 is 100% assembler IIRC, BTW. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As I'm sure this is related to your particular BIOS, we'll probably not get at debugging this one. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
