I couldn't agree more a valid dump from the chip either with a burner or a flash/dumping program is the way to go!
The bios I have has the correct ID but the dates don't seem to jive. My only guess is that Interactive Light the makers of SQ probably made further modification like stripping out txt and such maybe changing default settings but didn't change the ID. That's a big NO NO in my book but they probably figured these would never be seen again as computers.
PS.
Peter mentioned this aswell:
"Then the CHD metadata isn't acceptable to the BIOS - Award doesn't support drives with more than 16 heads. The cylinder count needs to be increased to 8908, and heads reduced to 15, but that requires recreating the CHD, because the current one is in the old format and can't be edited."
This is exactly why my first dump of the alt. site 4 didn't work! It is simple to fix that without a re-dump of the original drive.
