...stem hanging at Probing EDD, but after using 'edd=off' in the APPEND line I was successfully able to boot my kernel/initrd with syslinux-6.03 using a USB. So, lets assume my BIOS does not support EDD, but because it worked with USB (edd=off) so I assume one of the changes like (EDD, the __intcall() 16-bit interrupt mechanism has been replaced with direct function calls(32-bit) using ELF object support, memset() calls are added prior to intcall()) is responsible for not loading the kernel properly into the memory, PLEASE note, if I land into the boot prompt and call initrd first, that gets...

...at I'm trying to do is send (possibly receive) UDP packets via the PXE stack using the com32 API (using version 3.11 of syslinux). I have followed both the comboot API doc and the aforementioned thread; however they disagree on which registers are used for which bits of data in the setup for __intcall(). According to the comboot doc, to call the PXE stack's 'get cached info' function: Input: AX 0009h BX PXE function number ES:DI PXE data buffer Output: AX PXE return status code or, in com32 terms (the PXE call argument struct has been copied into the bo...

Hi I have tried to install syslinux 4.06 on the SD card again, it works like a charm. I am being very carefull with c32 files from the same version bootloader. No success. I am also unmounting /dev/sdb1 before installing syslinux, as mentioned in the given documentations. In the pasted syslinux.cfg content--- I have also tried using only one DEFAULT directive. No success. syslinux boots

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
