Description andrewo 2000-09-13 13:00:01 UTC 
System was installed with single Ultra2 Disc at unit 0 using installer and "dangerously dedicated mode"
Later 4 discs were added using the following procedure:
 dd if=/dev/zero of=/dev/rda1 count=2
 disklabel /dev/rda1 | disklabel -BrR da1 /dev/stdin
 newfs /dev/rda1c
With these new dangerously dedicated discs the system refuses to boot with the 4 new drives attached to the system.  The following is displayed immediatley after the PC Bios.
(leading zeros removed)
int=0	  err=0    efl=30246   eip=1b54
eax=0     ebx=38e  ecx=0       edx=0
esi=9ebe  edi=1a3e ebp=396     esp=38a
cs=c800   ds=40   es=93b3   fs=0   gs=0   ss=9ebe

ss:esp=00 00 3f 00 00 00 00 00-00 00 02 00 df 09 00 c8
BTX Halted

Fix: 

None
How-To-Repeat: Reboot, remove dedicated drives from chain or remove partition information.

Ignore this PR.  Fixed by flashing SCSI Bios to latest version. 2.57.2

Well, I'll close it, but it may be of use to someone else with 
the same problem one day. :-)

This is the same problem as in kern/16803. I mention this here
because kern/16803 also contains a solution if you can't
upgrade the bios which maybe the case when using on-board
controllers.
