RHBA-2013:1561 - Bug Fix Advisory
yaboot bug fix and enhancement update
Bug Fix Advisory
Updated yaboot packages that fix two bugs and add one enhancement are now
available for Red Hat Enterprise Linux 6.
The yaboot packages provide a boot loader for Open Firmware based PowerPC
systems. Yaboot can be used to boot IBM eServer System p machines.
This update fixes the following bugs:
- Previously, the client was overwriting the gateway IP address for the Trivial
File Transfer Protocol (TFTP) file transfer. When installing through the network
using VLAN tags, the boot failed when the server was in a different IP
subnetwork. This update ensures that the rest of the parameter strip can be
parsed correctly, and failures no longer occur in the aforementioned scenario.
- As there was not enough room between the first allocation and the bottom of
the firmware, user attempts to load a ramdisk failed when the firmware was at
32MB (0200000). This update adds the ability to be able to determine how big the
initrd memory will be yaboot . As a result, yaboot can accurately place a buffer
in the memory, and ramdisk load failures no longer occur. (BZ#968046)
In addition, this update adds the following enhancement:
- This update adds GUID Partition Table (GPT) support to yaboot, because
previously yaboot supported the DOS partition format which has a limit of up to
2TB for 512B sectors. So even if there are large disks, this limit forces users
to format all devices to 2TB. With GPT support in yaboot, users can now use
larger disks. (BZ#947101)
Users of yaboot are advised to upgrade to these updated packages, which fix
these bugs and add this enhancement.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
