gfxboot uses those three calls, but currently doesn't really handle returns from them. syslinux_boot_linux (lib/syslinux/load_linux.c) can return ("bail" label). syslinux_local_boot (lib/syslinux/localboot.c) has a comment which says "returns only on failure". The documentation for "Local boot" in doc/comboot.txt says "Does not return". Which is correct? syslinux...

...il because it thinks it has no space at the 1M load location but cannot relocate lnxboot.img. (In bailing, it gives the confusing error message "Bad file descriptor", not because that error actually occurred when attempting to boot the kernel, but because errno has that value on entry to syslinux_boot_linux and nothing clears or sets it.) Fix the regression by handling the corner case of no protected-mode code explicitly.

...2or64.c implements a com32 module that boots two different kernels with different initrds depending on whether the cpu has long mode support or not. I stumbled upon two problems while developing it with current git version (last commit 595705ffad4f63cfeb84e9bb1243df03808c2fff). The first was that syslinux_boot_linux didn't work for me. Both the command line and initrd data was garbage. The code I was developing is attached as l32or64_linux.c The seconda was that com32/include/syslinux/boot.h declares syslinux_run_kernel_image, but it isn't defined anywhere, so I went with syslinux_run_command.

3.80 is a bug fix and internal restructuring release. In particular, the entire shuffler subsystem has been rewritten largely from scratch, as has the Multiboot module. Changes in 3.80: * New shuffler mechanism and API. * Rewritten mboot.c32 module. * The syslinux_boot_linux() function has been simplified. * Don't hang trying to boot a "menu quit" label from the CLI. * Fix problem with boot-once "sticking" on some BIOSes. * isohybrid: fix problem with images over 2 GB in size. * APM poweroff module (poweroff.c...

I have updated syslinux in Parted Magic's test version to the 5.10 release. With 4.06 I booted plop like this: LINUX /boot/plpbt/plpbt.bin Now it says /boot/plpbt/plpbt.bin... ok Booting kernel failed: Invalid argument Other "extras" like IPXE, HDT, memtest86+, chntpw, Super Grub Disk, etc... all work with 5.10. Revert to 4.06 and plop works again. Is this a problem with syslinux

From: Matt Fleming <matt.fleming at linux.intel.com> This is a series of patches that, * shrink the core by moving things into an ldlinux ELF module * begin wiring up some of the C versions of various functions The core now only contains essential code and loads the ldlinux module to do everything else, like providing a command line interface and loading kernels.

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
