similar to: Chainloading DRMK

Here is a patch that makes it possible to chainload GRUB2 core.img form chain.c32. It reuses the grub= parameter (used for chainloading GRUB Legacy stage2): - both loaded at 0x8000 - start execution at offset 0x200 (0x8200 in memory) GRUB2 allows to specify another "GRUB home dir" than the standard /boot/grub GRUB2 doesn't allow to change the configfile 'grub.cfg' name

Dell has an ISO image (Dell version 5061A0, A5061) available here http://support.euro.dell.com/support/downloads/download.aspx?releaseid=R102625&fileid=132637 which contains an ISO with an hard disk image and no-emulation boot. I've estracted the hard disk image (size=2048000) and I'd like to boot it with isolinux. I tried kernel memdisk append initrd=dell5061.img The Dell/Dos os

The following patch for chain.c32 adds support to boot the Recovery Console of Windows NT/2K/XP. Normally when you want to boot the recovery console, you need to patch "cmdcons\0" into the bootsectorof the partition (8 bytes starting at 0x3 (4th byte)). We can do this patching in memory: strcpy((char *) 0x7c03, "cmdcons"); To boot the recovery console with chain.c32:

chain.c32 of SYSLINUX 3.82 does set the boot drive passed to the DL register to 0x80 and not to the boot drive (CD-drive). This can be a problem if you want to chainload grldr (grub4dos bootloader) from a CD and if you want to let grldr search for its menu.lst file on the CD.

Allow the grub loader to (optionally) support using a GRUB menu file. For example chain fs grub=stage2,grub.conf will load GRUB's stage2 and pass the (absolute) path to the file "grub.conf" in the Syslinux filesystem to GRUB's stage2. The path is passed to stage2 in GRUB's device/partition syntax (eg, "(hd0,1)/foo"). Note that we don't check whether the

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

Hi It would be pretty useful to have syslinux in linux kernel format so it can be chainloaded easy and directly by other bootloaders such as grub4dos. related topics: http://www.boot-land.net/forums/index.php?showtopic=7013 http://www.boot-land.net/forums/index.php?s=&showtopic=6119&view=findpost&p=59236

Hello, I'm trying to create and boot a Win98SE-DOS OS through Hard Disk emulation. My src files are from a Win98SE 1440K floppy image file, with a x86 boot sector (dl'd from the net - I have no floppy drive and a slow net link 3.2KB). I don't know what to put into the partition boot record of my image and how to load dos.bss properly (the docs explain for floppy images not for HD

Hello, I have found what seems to be a wee bit of a bug in the ISOLINUX menu. :) I have chainloaded a second menu as per the example at the very bottom of README.menu. When a menu item is selected in the second menu, <Enter> is pressed, the menu complains that it cannot find an image with the name of the label. So if the label is Image_1, it says it cannot find that. However, if

filename to GRUB Legacy GRUB Legacy reserves 89 bytes for storing the filename of the configfile from memory address 0x8217 to 0x826f. We allow overwriting the default value (/boot/grub/menu.lst) when grubcfg=<filename> is used together with grub=<loader>. Examples: chain.c32 fs grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst chain.c32 hd1,10 grub=/boot/grub/stage2

High all, In WinXP, I have created file "image.iso" using mkisofs, but unable to postprocess with the "isohybrid". I worked as follows: cd F:\syslinux-4.05\utils F:\syslinux-4.05\utils> isohybrid F:\image.iso and received >'isohybrid' is not recognized as an internal or external command, operable program or batch file. What next? Thanks in advance.

This adds (basic) support for GRUB stage2 image files. Loading a stage2 image will probably give you a GRUB prompt, with GRUB's "root" set at "(hd0)" (ie, entire first disk). Maybe the "root" will differ in less common setups. (One can of course select another disk and/or partition with GRUB's "root" command.) This has only been tested with version

As the first step, I want to thank everybody involved for making a majorly useful application! Second, here are the problems I see: Bug 1: if DEFAULT is not a tag, but a kernel name, menu.c32 fails loading. Bug 2: When menu.c32 returns to syslinux (on pressing Esc), the splash screen is not shown; Bug 3 or a missing feature: When grub.exe tries to return control to syslinux, it
