W83627HF/F
PRELIMINARY
The W83627F/HF is made to fully comply with Microsoft PC98 and PC99 Hardware Design Guide.
Moreover W83627F/HF is made to meet the specification of PC98/PC99's requirement in the power
management: ACPI and DPM (Device Power Management).
The W83627F/HF contains a game port and a MIDI port. The game port is designed to support 2
joysticks and can be applied to all standard PC game control devices, They are very important for a
entertainment or consumer computer.
Only the W83627HF support hardware status monitoring for personal computers. It can be used to
monitor several critical hardware parameters of the system, including power supply voltages, fan
speeds, and temperatures, which are very important for a high-end computer system to work stably and
properly.
