Turn off the new /sys/boot stuff (except boot0) unless OBJFORMAT is elf. (The BTX client must be ELF, though it is packaged as a.out for compatibility.)

Add NO_OBJ to those directories that don't make anything. For directories that don't many anything, add NO_OBJ=t just before we include bsd.init.mk. This prevents them from creating an OBJ directory. In addition, prevent defs.mk from creating the machine related links in these cases. They aren't needed and break, at least on stable, the read-only src tree build.

Prefer bsd.init.mk to src.opts.mk Final sweep to prefer bsd.init.mk to src.opts.mk everywhere as a design pattern. The rule is that all Makefiles in this subtree should start with .include <bsd.init.mk> so that we properly include ../Makefile.inc and defs.mk before anything else. Sponsored by: Netflix

Add isoboot(8) for booting BIOS systems from HDDs containing ISO images. This is part of a project for adding the ability to create hybrid CD/USB boot images. In the BIOS case when booting from something that isn't a CD we need some extra boot code to actually find our next stage (loader) within an ISO9660 filesystem. This code will reside in a GPT partition (similar to gptboot(8) from which it is derived) and looks for /boot/loader in an ISO9660 filesystem on the image.

SUBDIR.yes+= loader
Mega i386 loader commit. - Don't hard code 0x10000 as the entry point for the loader. Instead add src/sys/boot/i386/Makefile.inc which defines a make variable with the entry point for the loader. Move the loader's entry point up to 0x20000, which makes PXE happy. - Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE, instead use m4 to achieve this. Also, add a BTXLDR_VERBOSE knob in the btxldr Makefile to turn this option on. - Redo parts of cdldr's Makefile so that it now builds and installs cdboot instead of having i386/loader/Makefile do that. Also, add in some more variables to make the pxeldr Makefile almost identical and thus to ease maintainability. - Teach cdldr about the a.out format. Cdldr now parsers the a.out header of the loader binary and relocates it based on that. The entry point of the loader no longer has to be hardcoded into cdldr. Also, the boot info table from mkisofs is no longer required to get a useful cdboot. - Update the lsdev function for BIOS disks to parse other file systems (such as DOS FAT) that we currently support. This is still buggy as it assumes that a floppy with a DOS boot sector actually has a MBR and parses it as such. I'll be fixing this in the future. - The biggie: Add in support for booting off of PXE-enabled network adapters. Currently, we use the TFTP API provided by the PXE BIOS. Eventually we will switch to using the low-level NIC driver thus allowing both TFTP and NFS to be used, but for now it's just TFTP.

Restore kgzldr on i386 only I previously disconnected kgzdr based on a misunderstanding. I'd still like to transition to supporting only the loader(8)-based boot path for handling compressed kernels, but that can follow the standard deprecation procedure. This reverts r291113. Requested by: dteske

Collapse zfsloader functionality back down into loader. We no longer really need a separate zfsloader. It was useful when we were first supporting ZFS and had limited ability to properly boot off of ZFS without the special boot loader. Now that the boot loader has matured, go the way loader.efi pioneered and just build one binary. Change the name of the loader to load in the secondary boot blocks to be just /boot/loader. Provide a symbolic link from zfsloader to loader so people who have not upgraded their boot blocks are not affected. This has the happy benefit of making coexistence easier as well (fewer binaries in the matrix).

This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
