I've attached a Makefile that I wrote some time back and that was used to create the first bootable FreeBSD/sparc64 iso images. It should still work, but is a bit outdated now, in particular, you should be able to delete the 'boot1' and 'bootslice.sun4u' targets (replacing the latter with 'bootfs.sun4u') now by using 'disklabel -B' when building 'bootfs.sun4u', the zeroing mentioned in the Makefile does not seem to be required by the frimware. Note that you need to do most of the building on the sparc64 box (due to file system endianess issues, and of course to get the sparc64 toolchain). The mkisofs step is an exception, you can just copy over the files it needs and do it anywhere. - thomas -- Thomas Moestl <tmoestl@gmx.net> http://www.tu-bs.de/~y0015675/ <tmm@FreeBSD.org> http://people.FreeBSD.org/~tmm/ PGP fingerprint: 1C97 A604 2BD0 E492 51D0 9C0F 1FE6 4F1D 419C 776C --lrZ03NoBR/3+SXJZ Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=Makefile # $Id: Makefile,v 1.5 2002/03/19 17:17:57 tmm Exp tmm $ # Location of the tree to be burned onto CD-ROM ISOTREE?= /home/tmm/cdfs/isotree # Location of the src/sys tree to be used for building the boot block SYSTREE?= /mnt/tmm/sparc64/sys BOOT1DIR= ${SYSTREE}/boot/sparc64/boot1 BOOT1= boot1 LOADERDIR= ${SYSTREE}/boot/sparc64/loader LOADER= loader # Size of the boot file system in 512-byte blocks, including a disk label BOOTFSSZ?= 4096 MOUNTPT= fsmnt ALLTARGETS= boot1 loader boot.sun4u bootslice.sun4u sparc64.iso .PHONY: all clean all: sparc64.iso boot1: cd ${BOOT1DIR} && ${MAKE} all cp -f ${BOOT1DIR}/${BOOT1} $@ # XXX: non-standard options, dependency is bogus, so always do a full rebuild # for now. loader: cd ${LOADERDIR} && \ ${MAKE} clean all LOADER_DISK_SUPPORT=yes LOADER_NET_SUPPORT=no \ LOADER_NFS_SUPPORT=no LOADER_TFTP_SUPPORT=no \ LOADER_CD9660_SUPPORT=yes cp -f ${LOADERDIR}/${LOADER} $@ # Build the boot file system.
