>From the earlier patches - that simple fix for indexes not counting non-data partitions in gpt and mbr cases. Patches don't touch any other parts of the code at this stage - bigger stuff later for disklib as we agreed - but this is potentially useful right now. Michal Soltys (1): chain.c: fix public index value in mbr and gpt iterators

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

I upgraded my 7.0 system to 7.1-RELEASE with freebsd-update only to find that it no longer boots correctly, instead crashing with a BTX backtrace. If I break to the loader prompt and use 'ls /boot', I also get a backtrace. A new install of 7.1 on this hardware using a separate SCSI card and drive array also leads to a BTX backtrace. I have copied this below as the first (most

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.

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

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: *

So last week I was wondering if XFS was still working -- even with its last on-disk structure changes -- and it _suprisingly_ worked as expected. Right, now I can finally get rid of GRUB and use Syslinux to boot my Linux on EFI from a rootfs with xfs. Shit, I have two partitions (the first one being the required ESP) so there is no way to access the other partitions since because Syslinux does not
