of the physical size of the regular file. This is useful for presenting
ISO images to initiators, as in the following:
In /etc/iscsi/targets:
# present an ISO image
extent2 /usr/sets/20071214/release/iso/i386cd.iso 0 size
target2 ro extent2 any
% priv /etc/rc.d/iscsi_target restart
Stopping iscsi_target.
Starting iscsi_target.

Please note that the NetBSD initiator can mount (via vnd) an iSCSI target
presented in this manner. The Microsoft iSCSI initiator sees the read-only
target as a normal SCSI disk, and fails (not surprisingly) to initialize
the disk. It's now possible to make ISO images available via iSCSI, and
NetBSD will DTRT.
In read-only targets, don't attempt to seek to the last block and rewrite
it, it may not work.
Don't assign 8 MB of unused space for use in each iSCSI disk - just use
1MB, which will be enough for the scatter gather iovecs.
Get rid of some dead code.
makefile still needs work, and I still need to do some additional
fiddling here, but this is to be the unified rs6000/prep/bebox
mkbootimage eventually.
ACPI wakeup code and teach it how to start the APs again. As a side
effect the CPU_START interface allows choosing between different
bootstrap codes more easily now.
name the directory "02.config" as it historically was, name it config, so
that if we ever want to update this book for the modern age, we can move
chapters around, delete them, etc, without mass confusion.
This port of NetBSD is intended to run on MCA-based IBM RS/6000
machines. The port so far has only been tested on a 7006-41T, which is a
601-based RS/6000. The port also contains a limited set of code for the
7012-3XX machines, but support for those is a long way off still.
The port builds and generates a working kernel, however, it still lacks
bus_dma code for the MCA bus, so at present, only the com ports work,
though any other device (such as the printer/keyboard) located on the
ioplanar could probably be made to work. Work will continue on this port
as I iron out the DMA code.
This port was made possible by a generous gonation of hardware by Kevin
Bowling, who also provided much of the documentation for the port.
linux_sys_wait4. It worked except when child resources were requested,
because 32/64 bits struct rusage differs in size ...
While here, update linux32_sys_waitpid to use linux32_sys_wait4 with a
NULL rusage.
