iPXE allocates its first PMM block using the image source length,
which is rounded up to the nearest 16-byte paragraph. It then copies
in data of a length calculated from the ROM size, which is
theoretically less than or equal to the image source length, but is
rounded up to the nearest 512-byte sector. This can result in copying
beyond the end of the allocated PMM block, which can corrupt the PMM
data structures (and other essentially arbitrary areas of memory).
Fix by rounding up the image source length to the nearest 512-byte
sector before using it as the PMM allocation length.

The default initiator IQN is "iqn.2000-09.org.etherboot:UNKNOWN".
This is problematic for two reasons:
a) the etherboot.org domain (and hence the associated IQN namespace)
is not under the control of the iPXE project, and
b) some targets (correctly) refuse to allow concurrent connections
from different initiators using the same initiator IQN.
Solve both problems by changing the default initiator IQN to be
iqn.2010-04.org.ipxe:<hostname> if a hostname is set, or
iqn.2010-04.org.ipxe:<uuid> if no hostname is set.
Explicit initiator IQNs set via DHCP option 203 are not affected by
this change.
Unfortunately, this change is likely to break some existing
configurations, where ACL rules have been put in place referring to
the old default initiator IQN. Users may need to update ACLs, or

For performing installations direct to a SAN target, it can be very
useful to hook a SAN disk and then proceed to perform a filename boot.
For example, the user may wish to hook the (empty) SAN installation
disk and then boot into the OS installer via TFTP. This provides an
alternative mechanism to using "keep-san" and relying on the BIOS to
fall through to boot from the installation media, which is unreliable
on many BIOSes.
When a root-path is specified in addition to a boot filename, attempt
to hook the root-path as a SAN disk before booting from the specified
filename. Since the root-path may be used for non-SAN purposes
(e.g. an NFS root mount point), ignore the root-path if it contains a
URI scheme that we do not support.

Use the real-mode address ffff:0010 to access the linear address

This speeds up CPU mode transitions, and also avoids breaking the NBP

than true real mode and does not correctly emulate our transition into

Interestingly, Tivoli's VMM *does* allow us to switch into protected
mode (though it patches our GDT so that we execute in ring 1 rather
than ring 0). However, paging is still disabled and we have a 4GB
segment limit. Being in ring 1 does not, therefore, restrict us in
any meaningful way; this has been verified by deliberately writing
garbage over Tivoli's own GDT (at address 0x02201010) during a
