RE: port-i386/46247: 6.0 Beta boot fails on generic i386 architecture machine

["John Refling" <netbsdrat%gmail.com@localhost>]

More info on this:

SUSE Linux 10.1 [2006] installs and works on this machine.

Vista Anytime upgrade fails saying APCI is not compatible.

Points to the problem?

 Generally at printfs :-)
 I think there is one at the start of /boot (unless someone removed it).
 Since you aren't seeing that, something must be going on in the bootxx
code.
 bootxx only has access to 'print string' and 'print value' functions,
 but they are usually enough.
 
 I'd make sure there are no 'clear screen' calls, then output somthing
 just before bootxx jumps into /boot, and something right at the top
 of /boot.
 
 Might be a size issue...
 Maybe some of the memory areas used contain bios data (I've NFI how
 to find out which areas are actually usable while you still want
 to make bios calls).
 
 If you suspect bios issues, can be worth using the direct serial
 console versions of stuff - in particular the code can then write
 from 32bit mode without having to switch to 16bit code for the
 bios call.
