a simple version of bcopy() so we avoid picking up the overly-complex
implementation in libc (via libstand). This is not necessary on
-current, but RELENG_4 has apparently just exceeded the 15-sector
limit for boot1.

larger than 8k. We now use 4k buffers regardless of the filesystem
block size, so there is no longer a static limit.
Simply increasing the buffer size from 8k to 16k as done on the
i386 doesn't work on the alpha, probably because it causes us
to overshoot boot1's 48k runtime memory limit.

All the alpha loaders should use the same version file. Also, we might
should merge the various loaders (cdboot, loader, netboot) into one loader
that can boot off of disks, CD's, and network devices. The version bump
is needed so the FICL scripts won't bomb out thinking that the netboot
binary is too old.
- Change the 'fopen' keyword to accept a mode parameter. Note that this
will break existing 4th scripts that use fopen. Thus, the loader
version has been bumped and loader.4th has been changed to check for a
sufficient version on i386 and alpha. Be sure that you either do a full
world build or install or full build and install of sys/boot after this
since loader.old won't work with the new 4th files and vice versa.

make(1) wants to build loader.sym *before* the .o files. Eliminating
one seeminly intermediate step avoids the problem. Somehow, it seems
that variables are not getting expanded at the right time.
Any explanations would be appreciated...
Changing:
${BASE}.sym: ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o
${LD} ...
To:
BASEOBJS= ${OBJS} ${LIBSTAND} ${LIBFICL} ${LIBALPHA} ${CRT} vers.o
${BASE}.sym: ${BASEOBJS}
echo ${BASEOBJS}
${LD} ...
.. the echo only shows LIBFICL, CRT and vers.o. ${OBJS} is not included.
The release engineer keeps using the wrong /boot/cdboot when creating the
ISO images. So we'll add the 4.0-RELEASE cdboot to the tree until someone
bothers to fix the source so a working `cdboot' is built.
to reinstall boot1 after a 'make world'.
Unfortunately this means that people who have already installed a new
boot1 from a 'make world' after 2000/09/18 *must* reinstall it after
their next build using something like:
# disklabel -B /dev/da0c
expands beyond the limit we will extend the address space before trying
to zero the BSS. This should give us plenty of headroom for modest
expansion of the loader.
only doing so if loader.rc does not exist. This fixes the problem where
installworld doesn't update /boot/loader.4th, resulting in device.hints not
being loaded after updating past the config(8) changes, which resulted in
mcclock0 not being probed, and a nice kernel panic during boot.
FICL. bootforth is now live on the Alpha!
**BEWARE** - you *MUST* build and install a current libstand or you will
most likely get zfree() panics at loader startup.
We should now be able to set up the loader.conf stuff on the Alpha too.

This is almost certainly an alpha infrastructure bug, not a FICL
problem. It's probably the same thing that made FICL fail for no
apparent reason on the Alpha.

bcache_strategy() instead of after.
The actual fix is sligthly different for the one in the PR.
