similar to: Load ELF module in code

Hi! Nowadays Syslinux uses regular dynamically linked ELF files as it's modules: [...] com32: Switched from the COM32 object format to ELF as it is a much more powerful format that allows undefined symbols to be resolved at runtime and dynamic loading of module dependencies, which means modules now become shared object files instead of statically linked binaries - reducing both disk space

Btw, I already found a way, though not perfect: - Create a FAT bootable disk image using "syslinux --install". - Copy hello.c32 module and load it in syslinux.cfg. - Find the

Hi, I'm trying to figure out how to link against symbols from the core com32 shallow module at runtime. I see references to _root_.c32 (EXEC_ROOT_NAME) in com32/lib/sys/module/exec.c, but can't find where this module is created in the build infrastructure, if indeed it is created at all. Does anyone have any pointers?

Hi, I'd like to load with pxelinux an RTEMS executable file, the format is ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, strtipped Can someone tell me if there is a way to load it with PXElinux. When I try to do it, the error message is : invalid or corrupt kernel image Thanks for your help. Regards. Stephane ARQUER

This plays a tune through the PC speaker and is compatible with the GRUB2 command of the same name.

Hi folks, Syslinux 5.00 is out in time for the holidays. This release includes a lot of changes from 4.06. I've included the NEWS entries below, which highlight the major changes. Lots of assembly code has been rewritten in C, which makes further development much easier (and also really helped for the 'firmware' abstraction that appears in Syslinux-6.00-pre1). So be on the lookout

Hello, today I upgraded from Syslinux 4.06 to to Syslinux 5.00. But now the system won't boot anymore and I get the message Failed to load ldlinux.c32 Boot failed: please change disks and press a key to continue What I have done: 1) Installed Syslinux 5.00 2) Reinstalled "mbr.bin" to /dev/sda and /dev/sdb using dd bs=440 count=1 conv=notrunc

I'm seeing some sporadic build failures with 'make -j4'. The failures are: make[4]: *** No rule to make target 'hello.c32', needed by 'all'. Stop. I've only seen the failures with com32/samples/hello.c32 and com32/rosh/rosh.c32. I'm not a make expert, but I think it's due to missing dependencies. This patch seems to fix my failures, but I'm

Issue Statement: PXE booting from BIOS systems works fine on both 6.03 and 6.04-pre1. New clients only support (u)EFI which results in the inability to load remote kernel or initrd. Tested with both Syslinux 6.03 and 6.04-pre1. So far unable to boot any (u)EFI clients unless both initrd and kernel are on PXE server. Using packet captures I see that the URI request for the remote file on the repo

Ive seen the GSOC 2008 mod for allowing dynamic loading of ELF modules and it fits exactly what we need. 1) It mentions it will be part of syslinux 4. Is there an estimated release for syslinux 4? 2) The docs are amazingly sparse. Aside from one partial usage note, there appear to be no text files, man pages, html.. nothing. Only thing I could find was looking in source at the print_help

Hello, I use Tim's mboot.c32 to load multiboot kernels over pxelinux. However, some kernels require the symbol table and other information in the ELF section header table to be able to load properly. This functionality is not present in mboot.c now, so I added support for it. The patch is attached. It would be great if you can push this into the next release of syslinux so ELF multiboot

I'm having issues with the ifcpu[64].c32 modules. I am building a menu system (as opposed to the command line only options I was previously using) to make it easier for my boss to use PXE. I discovered the modules for auto detecting the CPU and thought hey, that's great! However, I'm having an issue where when I select to boot say System Rescue CD, it drops me to the command line

This patch adds to Com32 modules the capabilities of accessing the EFI environment The idea is simple, the EFI parameters "image" and "table" received by syslinux.efi's efi_main() are stored in the "firmware" structure, next they are retrieved from the Com32 module which is linked against the gnu-efi static library. The Com32 module can use the EFI
