Makes the 64-bit alpha checksum magically contain an embedded 16-bit
Sun (NetBSD/sparc) compatible magic number and checksum. This is the
last piece in the "boot one disk from alpha, sun, and i386" problem.
.
And for those who told me this had been done before, :-P. It turns out,
it was only done in the collective sense by multi-disk distributions.
had a few bugs fixed that let the problem slip in, and since bootxx's
Makefile now goes out of its way to satisfy installboot's undocumented
and totally unreasonable assumptions about the bootxx file it's operating
on. No point in fixing the assumptions, because sooner rather than later
this incarnation of installboot is going to die.
assuming that there's always going to be space for the whole boot
block info struct. (the assumption would cause a malloc'd region
to be overrun, if it proved false.)
an absolute block address. It's cheating, as the motivation is support for
the libsa ustar tfs `filesystem' and the solution symmetrical to ufs and
cd9660 would have been to teach installboot about tfs. However, it still
would have been different as you can't mount a tfs with the kernel, and
this option gets possibly useful support for any contiguous format, even
completely raw boot images.
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.
