This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

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

From: Raphael S. Carvalho <raphael.scarv at gmail.com> Wrote the documentation below. I think it would be good to push the doc to the wiki as soon as the UFS support gets merged. Unix Fast File System (UFS/FFS) 1/2 on Syslinux - (usage/install) ----- There is a confusion about the name of this file system, then I decided to contact the author who replied: "The name has always been

From: Raphael S. Carvalho <raphael.scarv at gmail.com> Change since v1: * Fix bug on dentry structure (thank you specification; btw, sarcasm), and consequently a bug on ufs_readdir. * Add readlink support (applied tests for symlinks whose destionation path were stored in blk pointers and the file itself). * Several improvements. Wrote the documentation below. I think it would be good to

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
