My original install had a broken set of bootblocks that didn't accept they keyboard break as expected. I had never got around to refreshing them with a disklabel -B da0. I ended up getting out of it by: - creating an alpha boot floppy using the SRM "bootable" checksum tweaks on an i386. You could once do this by manually activating the #ifdef __alpha code to calculate the checksum. - I got the old loader and bootblocks etc from beast.freebsd.org I think. - I do not remember from there, I'm pretty sure I was able to boot from floppy ("boot eva0" ?), then change the root device to the disk and load the kernel from there.
