Note:

BIOS dates may vary without changes to the revision code, especially for non-IBM machines.
This BIOS call is not implemented in these early versions or under Linux's DOSEMU. Read the Model byte at F000h:FFFEh and BIOS date at F000h:FFF5h instead.
These BIOS versions require the DASDDRVR.SYS patches.
These Olivetti and Epson machines store the submodel in the byte at F000h:FFFDh.
