...t Fleming, Intel Open Source Technology Center > I tried it with pre11, same problem. I modified the debug append line to the one above. I get the following output: efi_boot_linux: kernel_start 0x1000000 kernel_size 0x472390 initramfs 0x7e3dc998 setup_data 0x0 cmdline 0x9f000 efi_boot_linux: setup_sects 32 kernel_size 4662160 Hope this helps Regards Michael

This series: 1. Updates the boot protocol to version 2.07 2. Clean up the existing build process, to get rid of tools/build and make the linker do more heavy lifting 3. Make the bzImage payload an ELF file. The bootloader can extract this as a naked ELF file by skipping over boot_params.setup_sects worth of 16-bit setup code. 4. Update the boot_params to 2.07, and update the kernel's head.S to jump to the appropriate subarch-specific kernel entrypoint. The very earliest code is common (copy boot_params, clear bss); the split happens just before the initial pagetable setu...

At least we know it's taking the 32-bit entry path. I opened the following bug report to track this issue, http://bugzilla.syslinux.org/show_bug.cgi?id=21 Does vmware display the register conten...
