lost with booting

Wed Sep 8 01:56:41 PDT 2004

okay. this means we should definitely break after a BTX error and *not* 
somehow return to business (I've seen a iret somewhere). maybe *then* 
we can track the issue.

somehow it seem that *either* esp/ss gets shifted to an area that is 
full of 0xff *or* something overflows and kills the whole stack. Or am 
I on the wrong track?

cheers

I now know for 100% certainty I haven't gotten a mix.

Each and every time I made sure bootblocks were installed.
I also used fdisk with p 2 0 0 0 to remove the partition before I 
recreated
it with fdisk and p 2 165 255996720 142294320.

   If you are trying to boot a dragonfly slice, you must have 
dragonfly
   boot1/boot2 blocks installed on that slice.  That is, you have to 
proper
   disklabel the slice, for example:

   disklabel -B ad0s2
Even used disklabel -Bi ad0 and supplied the information from my disk 
(which
is set to auto in BIOS, which is CHS - 65525/16/255, LBA being
16643/255/63).

   In the past we have found that 'garbage' in the slice can screw up
   booting, so to be totally safe I'd blow it away completely and 
reinstall.

	dd if=/dev/zero of=/dev/ad0s2 bs=32k count=16
	disklabel -r -w ad0s2 auto
	disklabel -B ad0s2
	... reinstall dragonfly from scratch on that slice ...
Same issues.
DF just refuses to boot.
It gets as far as printing - and then scrolls a BTX error/dump and 
resets
just as fast, only because I see the remnant glow on the monitor I 
know it
said BTX halted.
