Here is a short primer on what it is: The iBFT is an equivalant to the Boot Flag, except that its geared towards iSCSI and hence requires much more information (such as the IP of target, passwords, which device to login, etc). iBFT is a data structure populated by the BIOS or the NIC to contain this so that the OS can read it and login to the iSCSI and present the boot device to the initrd for mounting / FS. There has been two big features added in: 1) Updated to support the 1.03 of the spec: ftp://ftp.software.ibm.com/systems/support/bladecenter/iscsi_boot_firmware_table_v1.03.pdf 2) Split in two modules: one presentation that exports SysFS entries and the other that actually contains the iBFT data. The presentation driver paves the road for iSCSI hardware drivers (QLogic iSCSI HBA for example) to present the boot information they contain via this SysFS interface as they don't put the data in iBFT format. Please pull the 'for-linus' branch of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/ibft-2.6.git for-linus Thank you!
