similar to: Recovery console doesn't work in chain.c32 3.85 or 3.86-pre1

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: *

Syslinux 3.85 is a bug fix and minor new feature release. The biggest change is undoubtedly that gPXELINUX is now considered feature complete, and should be able to be a drop-in for PXELINUX for all uses. Special thanks to Intel Corporation, my current employer, for their support for my Syslinux work. Changes in 3.85: * gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP

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

Correct the "seg=" value(s) corresponding to the "reactos=" option for chain.c32. The correct segment parameter should be "seg=0x0F80", instead of the incorrect / failing ones "seg=0:0x8000:0x8100".

Grub Legacy stage2 will read the install_partition variable from memory address 0x8208.

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

Look into the original XP cd and see where NTLDR is located, then place it on your cd in the same directory and it 'should' work. I have created some 2000 XP boot cd's with integrated recent service pack's and they still boot. But I do that with cdrecord+original boot sector, not with any isolinux stuff... But I hope this help! -----Original Message----- From: G. Murali

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

The domain feature was eliminated because of pricing reasons as well as technical

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.
