# $FreeBSD$
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.

Implement a simple LRU block cache. By default this is initialised to 16k, and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics.

Resynch with working sources before BTX integration. - Use format-independant module allocator. - Conditionalise ISA PnP support. - Simplify PnP enumerator interface. - Improve module/object searching. - Add missing depend/install targets in BTX makefiles. - Pass the kernel environment and module data in extended bootinfo fields. - Add a pointer to the end of the kernel + modules in bootinfo. - Fix parsing of old-style kernel arguments.

OpenFirmware/PowerPC loader, part 2. As of this patchset, the loader builds (under NetBSD/macppc), boots, interacts and talks to BOOTP/NFS servers. (main.c was moved from boot/ofw/libofw to boot/ofw/common but has no revision history) Reviewed by: obrien

Add BootForth hooks; if BOOT_FORTH is defined, pass every line read to the Forth interpreter. Instantiate all of our inbuilt commands as Forth words, and handle them being called from there. Add my copyright to the bcache module (oops).
