Another problem: during IBM VGA ROM initialization, a "missing readByte handler" warning occurs.
Card.setMemoryAccess(0x1510): missing readByte handler
stopped (2351185 ops, 7740201 cycles, 1617 ms, 4786766 hz)

Before debugging this though, I decided to first make a table of all the register values for most of the modes that
the IBM VGA supports:

In the process of building this table, I also discovered that INT 0x10 mode 0x0D display is garbled, and that all
graphics modes >= 0x0D are misdetected as BIOSMODE 0x12.
All these issues are under investigation.
