1919    TODO (PC-9821):
2020    - fix CPU for some clones;
21    - "cache error", there might be "windowed" RAM at 0x80000-0x9ffff (hence the RAM POST
22      that stops at 512k)
21    - "cache error"
22    - undumped IDE ROM, kludged to work

2425    TODO: (PC-486MU)
2526    - Tries to read port C of i8255_sys (-> 0x35) at boot without setting up the control
2627      port. This causes a jump to invalid program area;
