similar to: Patch mboot.c with Symbols/segments loader for multiboot ELF kernels

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

From: Ralf Ertzinger <ralf at skytale.net> If a loaded kernel is in ELF format and contains a multiboot header indicating valid relocation information, prefer the informations from the ELF header. This is in violation of the Multiboot spec, but it's the way GRUB does things and Solaris kernels rely on this behaviour. Signed-of-by: Ralf Ertzinger <ralf at skytale.net> --- diff

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

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

hpa etal, Im trying to get PIRT running on an SBC which has no CD-ROM drive. (an 8 MB ISO which demo's RTAI - RealTime Application Interface, on linux patched with Adeos) (BTW, PIRT uses isolinux) anyway, Im trying to use pxelinux to chainload / memdisk / mboot it, Im having no success. Ive also tried booting memtest86, which I can boot on my laptop using grub, ie title memtest

This is a resend since I didn't hear back from anyone. Hey guys, I noticed the appended ipappend options end up in the beginning of the cmdline argv[] when mboot is entered. mboot then tries to parse the first argument as the name of the kernel module and promptly fails cuz it can't find "ip=.." or "bootif=...". I'm attaching a patch which basically looks for any

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 >=

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

Hi, This patch ensures that mboot.c32 will always jump to a physical address when loading a Multiboot kernel. Some kernels are linked with a virtual entry point and without this patch these kernels are unbootable.

I'm attempting to PXE boot a XEN dom0 kernel version 2.6.16, xen version 3.0.2-2.

I'm currently trying to integrate ReactOS's bootloader into my concept bootdisk with standard layout. It uses Syslinux 4.10pre15. This is failing on two parts: 1) bootsector method only works if specifying huge cluster size (16KB) 2) Multiboot method fails due to opening bootloader's configuration file from harddisk instead of bootdisk.

Hi all, I'm trying to use mboot.c32 to build our Solaris machines but the problem we are getting is the network interface doesn't get configured. It would boot in to the miniroot and then drops in to a shell. At the shell, if I configure the interface via dhcp it would continue on with the jumpstart. This is the first time we are using syslinux (version 4.04) and looking at the

Hello, I noticed after upgrading from 3.20, I haven't been able to get syslinux to boot properly with menu.c32 or mboot.c32 from a USB key. I get an error saying invalid kernel when its trying to load menu.c32 or mboot.c32 (or any other kernel for that matter). I tried 3.35 and 3.36-pre5. Same exact behaviour. I'm using the following to compile: gcc version 3.2.3 20030502 (Red Hat Linux

If you have a multiboot kernel which is booted by syslinux/pxelinux/isolinux, etc., is there a way to determine who actually is the bootloader among the three? I'm wondering if the multiboot header or any part of memory has a consistent identifier somewhere. thanks, Ram

Hi all, I'm attempting to PXE boot ESXi, which uses the syslinux mboot.c32 module. The mboot.c32 included with ESXi seems to be an older version that runs into an "out of memory loading.." problem halfway through, even though the box has 8GB memory. This may be related to NUMA, since it works fine on an older box but not the newer blade. I saw that some non-contiguous memory issues

Hello Xen-users, I am trying to load two executables into a single VM at different addresses. The goal is to pass control to the first executable, which will treat the second executable as data. Can PV-Grub be used to accomplish this? I suspect ordinary Grub should be able to do this, outside of Xen, with a configuration like this: menu.lst: title a multiboot test root (hd0,0)

I am working with multiboot module "mboot.c32". I have had luck using it to boot NetBSD and the Hurd kernel. The problem with booting the Hurd kernel is apparently connected to the extended syntax passed along to it by grub. Grub passes Hurd kernel approximately 4 files, some of which are modules, and another ten (or so) boot arguments, which correspond to those modules and kernel. The
