Hi,
I think I've at last found a bug in elfboot.c.
Until this fix, I had always needed to disable verify code in
elfboot.c to get it work.
Now it boots ELF kernel with BOOT_IDE perfectly.
One of doubly-linked chain was not initialized.
I think it did not cause problem when memory near address 0 comes
up with zeroes.
But my raminit.inc leaves gabages there so some bogus memory ranges
have been included in checksum.
