similar to: chain.c32 add grldr= command for Grub4dos

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

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

filename to GRUB Legacy GRUB Legacy reserves 89 bytes for storing the filename of the configfile from memory address 0x8217 to 0x826f.

The Windows recovery console doesn't work with chain.c32 3.85 or 3.86-pre1. COM32 chain.c32 APPEND cmldr=/cmldr Initially reported by cdob at: http://www.boot-land.net/forums/index.php?showtopic=10487#entry94001 It did work fine with the: "chain.c32: Handle nonlinear logical partitions" patch.

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.

Grub Legacy stage2 will read the install_partition variable from memory address 0x8208. We only need to change the value at 0x820a to the correct partition number: -1: whole drive (default) 0-3: primary partitions 4-*: logical partitions Signed-off-by: Gert Hulselmans <gerth at zytor.com> --- com32/modules/chain.c | 13 ++++++++----- 1 files changed, 8 insertions(+), 5

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:

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: *

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

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates
