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

Peter, Is this page update to date? http://www.kernel.org/git/?p=boot/syslinux/syslinux.git;a=shortlog I sent a multiboot symbol table loading patch (syslinux-3.11-mboot-sym_table-patch) a few months ago and I thought you have checked it in. I didn't follow up after that. But i dont see it in the changes now, should i resend it? thanks, Ram

Hi All, Now that we have multiboot capable pxelinux, thanks to mboot.c32, I decided to try and remove pxegrub from my x86 jumpstart infrastructure since, in theory, pxelinux can now do it all. The problem I'm having is I'm not very sure I'm following Tim's documentation correctly... I'm not 100% what comes after the --- and whether the Sun kernel needs it's arguments

I''ve now given up trying to get grub working with my particular e1000 adapter, I''ve tried all the patches and all I can get is something that works a little bit but never past the grub menu. I''m sure I read something somewhere about a tool which would combine a multiboot image + modules into a single bootable item which could be loaded by lilo, and am hoping that the

From: Tim Deegan <Tim.Deegan at cl.cam.ac.uk> Fix register constraints of final jump to kernel entry.

Hi all, I've started writing a new mboot.c32 using the Syslinux native APIs; it is currently on the new-mboot branch of the Syslinux git repository. However, I don't have a huge number of things which use Multiboot set up to test, so I'd really appreciate it if you're a user of mboot.c32 to help me try this and report back positive or negative. I don't have the Solaris DHCP

The program segments loaded presently in mboot.c only consists of a subset of sections described by the ELF Section Header Table (SHT) in the ELF kernel binary. Segments with useful information often needed for debugging purposes (symbol tables, string tables, etc.) aren't usually present in the program segments and hence not loaded above. Some kernels use this debugging information to

It can then use disc access (not PXE), or you can pass it the ?real? kernel, but also e.g. configuration files, as Multiboot

Hello, I get the following message while loading my multiboot kernel with mboot.c32: "Invalid Multiboot image: neither ELF header nor a.out kludge found". I checked the code and came across this (com32/mboot/map.c line 130) : if (i + mbh_len < len) mbh_len = 0; /* Invalid... */ else break; /* Found something... */ } Shouldn't it be "if (i + mbh_len >=

I'm attempting to PXE boot a XEN dom0 kernel version 2.6.16, xen version 3.0.2-2. I've built syslinux-3.20-pre8 from source and am using the following config: DEFAULT mboot.c32 xen-3.0.2-2.gz dom0_mem=258048 --- vmlinuz-2.6.16-xen0 ro console=ttyS0 root=/dev/sda1 --- initrd.img Where initrd.img is my own custom initrd that I've built to do some pre-setup before booting to the real

Hi list, I've noticed that there are a number of binaries in syslinux-4.02.tar.bz2, which seems a bit odd. Even stranger is that I get different syslinux behaviour depending on whether I rebuild these or use the ones from the tarball. To use the ones from the tarball I: $ make clean $ make installer $ make install-all ... whereas to rebuild everything from source I: $ make

How do I use that in the generic case? The ?pxebsd.0? file can be called as? ? PXE loader ? COMBOOT (16-bit) ? DOS .COM ? Multiboot (although it switches back to 16-bit mode

Hi, I'm trying to get to the bottom of a problem using the combination of tboot (http://tboot.sf.net, trusted boot kernel for Intel TXT) and extlinux. TBOOT loads using the multiboot protocol, where the tboot "kernel" is loaded as the kernel, and the actual linux kernel and initrd are specified as modules. A working grub configuration looks something like:

Okay, MediaWiki syntax docs follow. Note I have tested those only a bit, and not within the vesamenu context, but if mboot.c32 resets to

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
