 I can reproduce this with 6.1-RELEASE CDs on an Itox Expanding Dragon 1U 
 with an external USB DVD+-RW drive. John Baldwin speculates it is due to 
 the redirected BIOS interrupt routines which use USB needing to be 
 called in real mode, not vm86 mode.
 There is no quick and easy fix for this, but if I get around to it I 
 will try to hack btx.
