>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.

This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal

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

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: *

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
