...ch to make it work again. With COM32, it is no longer possible to use preprocessor directives to determine the SYSLINUX variant. The code inside the #if will never be compiled. So, I changed it to use syslinux_filesystem() to determine the variant. Also, I moved the relevant code from kernel.c:new_linux_kernel() to load_linux.c:bios_boot_linux() because there is no convenient way in new_linux_kernel() to control the boot flags value. In basic testing, keeppxe seems to work with the patch applied. --- syslinux-6.04-pre1.orig/com32/elflink/ldlinux/kernel.c 2016-03-01 21:06:02.000000000 -0800 +++ sysli...

From: Matt Fleming <matt.fleming at intel.com> The following patch series is available at, git://git.zytor.com/users/mfleming/syslinux.git elflink All patches are against the 'elflink' branch. This series fixes a few serious bugs and some behavioural incompatibilities with the 4.x series. Matt Fleming (19): ldlinux: Initialise 'p' before using it. ldlinux: Parse

Hi, I encounter a problem with Syslinux 5.00 I cannot really describe. So I created two small videos: Booting with Syslinux 5.00 (1.3 MB): <https://www.dropbox.com/s/b6g8cdf2t9v48c6/boot-syslinux5-fail.mp4> How I fixed the problem by downgrading to Syslinux 4.06 and how booting should look like (6.5 MB): <https://www.dropbox.com/s/lt7cpgfm0qvqtba/boot-syslinux5-how-i-fixed-it.mp4>

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. The config file parsing

From: Matt Fleming <matt.fleming at intel.com> Here are the patches that I've got queued up based on the very helpful feedback I received from people testing Syslinux 5.00-pre9. Unless anyone has any concerns these will make it into Syslinux 5.00-pre10. Matt Fleming (9): pxe: Don't call open_config() from the pxe core ldlinux: Print a warning if no config file is found

From: Matt Fleming <matt.fleming at linux.intel.com> These patches are based on the elflink branch. This set of patches is my attempt at moving the command-line interface functionality out of the core and into an ELF module to reduce the size of the core. The most interesting patch is [PATCH 4/4] which moves the cli code out of core/elflink and into com32/elflink/modules. [PATCH 4/4] is
