I created a 2.88 floppy with VFD, installed HXDOS... attempting to run anything HXDOS related = "Unimplemented: #NP handler Execution stopped" from V86 - I thought I would give it a try.

Looked at it after some sleep. Noted the following when booting via copy.sh:

- InitDiskno hard disks detected                                               
Can't disable A20 - ignored
FreeDOS HIMEM 2.07 [Feb 13 2003] (c) 1995, Till Gerken 2001-2003 tom ehlert     
Interface : XMS 2.00 80386 64MB

Same image "booted" via DosBOX (boot freedos722.img):

- InitDiskno hard disks detected                                               
FreeDOS HIMEM 2.07 [Feb 13 2003] (c) 1995, Till Gerken 2001-2003 tom ehlert     
Interface : XMS 2.00 80386 64MB

So the A20 line isn't supported which is the same thing mentioned by marcov New Xeon's no A20 with a mention that FreeDOS's HIMEM now works around this. Japheth, is this something HXDOS could also work around in this type of situation? Might be helpful with other emulators, the new boards coming out.
