[comp.sys.ibm.pc] Corona luggable BIOS updates?

miker@csupwb.colostate.edu (Mike Riley) (09/03/89)

Does anybody have any experience with luggable Corona PC clones (specifically
the ROM BIOS)?  I have a friend that would like to upgrade from DOS 2.11
to 3.3 or similar, plus use an EGA card and monitor, but his BIOS version
is too early (at least for the EGA - I'm not sure what's involved with
changing over to DOS 3.3, although I suspect the Coronas had a weird
memory structure that caused problems if you added more than 512K of RAM.)

Does anybody know of a source of BIOS chips?  Is it possible to use plain
vanilla ROMs, say from Phoenix etc.?

Any assistance would be greatly appreciated.  Please e-mail replies, and 
if there's enough interest (which would surprise me), I'll post a 
summary. 

Thanks.
