Hmm, I am really at a loss for what is trashing 'dsk'.  You could
possibly try adjusting bios_getmem() to force it to use
high_heap_size from bios_extmem (that is at the bottom of the
function) perhaps.  However, that is mostly a bit of a guess that
some part of your BIOS is randomly zero'ing dsk.

I'm at a loss as to how the assignments to bootinfo would trash
'dsk'. :(
