W2100z Supplemental 2.5 XpReburn produces non-bootable ISO in Solaris Sparc

Question

Just posting in case helps someone else...
The XpReburn script from the W2100z Supplemental 2.5 CD is commented as being able to run on Solaris Sparc:
# This script was developed on Solaris X86. It will run on Solaris Sparc
# and Red Hat Enterprise Linux 3. It is not guaranteed to work unmodified  
# accross all versions of Linux. This script is experimental. Some end user
# MODIFICations may be necessary for it to run on other linux distributions 
# and system configurations.Running XpReburn under Solaris Sparc 10 produced an .ISO image apparently without error, but the resulting image would not boot.
Found the cause of the non-bootable image was the following section of XpReburn. It was using dd and od to extract 16-bit LBA values. On Solaris Sparc it ended up reading little-endian values as big-endian, hence extracting the boot loader from the wrong part of the XP CD. To get it to work under Solaris Sparc added conv=swab twice as shown below:
# Read the boot loader from the CD into the image directory as a file. This process takes
# several steps because the boot record has to be consulted to locate the RBA (the
# starting LBA of the boot catalog). The boot record always resides at LBA 17
${ECHO} "Reading WinXP Boot Loader from CD..."
${ECHO} "  Looking up boot catalog lba from boot record..."
${DD} if=$CD_DEVICE bs=2048 count=1 skip=17 | ${DD} bs=71 skip=1 count=1 | ${DD} conv=swab bs=4 count=1 of=$SCRIPTDIR/foo
BOOTCATLBA=`od -d $SCRIPTDIR/foo | ${AWK} '{print $2}'`
${ECHO} "  Boot Catalog is at LBA $BOOTCATLBA, looking up boot image LBA..."
${DD} if=$CD_DEVICE bs=2048 count=1 skip=$BOOTCATLBA | ${DD} bs=40 skip=1 count=1 | ${DD} conv=swab bs=4 count=1 of=$SCRIPTDIR/foo
BOOTIMGLBA=`od -d $SCRIPTDIR/foo | ${AWK} '{print $2}'`
${ECHO} "  Reading Boot Image from LBA $BOOTIMGLBA..."
${DD} if=$CD_DEVICE bs=2048 count=1 skip=$BOOTIMGLBA | ${DD} bs=2048 count=1 of=$IMAGEDIR/$BOOTIMAGE
${RM} -f $SCRIPTDIR/fooWith the above mod, XpReburn generated an image which booted the XP Pro installer and allowed XP to be installed.

Michael,
Reading the submission guidelines it appears BigAdmin is for you own work:
By submitting content to the BigAdmin portal, you are attesting that your submission is your own non-confidential property and does not infringe the intellectual property rights of any party.
Whereas my "hint" above is really a bug report / enhancement request for a Sun supplied script.
I only have a basic support plan so don't think I can raise a bug report.
Also:
1) The modification listed was a quick hack to get the script to work under Sparc Solaris, but which would have caused the script to generate a non-bootable ISO if run under X86 Solaris.
2) If you run the script on a ZFS filesystem you get an error that the filesystem isn't local - the script should be updated to consider a ZFS filesystem as local.
3) If the script is run on a Solaris system with two optical drives, the script fails with an error because fails to correctly read the volume name of the XP CD. Can't remember the details, but just hacked the script to work.
So, so for now will just leave the "hint" in this thread.
