Actually, it is making the difference, I must have used a wrong disk when testing. It's working fine. So I've applied the patch. And while "looking deeper", it turned out that there is a scary timebomb in kern/i386/pc/startup.S. Only the initial part of that file is supposed to be uncompressed, but in fact, the error handlers of the decompression function itself were spilling into the compressed area. Adding even minimal debugging code would push the main part of lzo1x_decompress() beyond the boundary defined by GRUB_KERNEL_MACHINE_RAW_SIZE, which would crash even before "Welcome to GRUB". So I've applied another patch that assures that to uncompressed code stays below GRUB_KERNEL_MACHINE_RAW_SIZE. It would be nice to avoid any constant here and make grub-mkimage.c use a label in the image, but it would need more work and more testing. -- Regards, Pavel Roskin _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
