Serious problem found in the DUAL BOOT option for MS OS/2 1.10 toolkit
 
The boot sector for C: (or what ever) that it creates has
a bad assumption coded into it.  It assumes AX is 0 when in
fact most (all the ones I checked, over 10) hard drive MASTER
boot records leave 55AA in AX since they just verified that
the sector was a boot sector.
 
Easy to patch in some since you can just xor AX,AX before jumping
from the MASTER boot block to the PARTITIONS bootblock.
