K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500
Kb/s or 1 Mb/s. It also provides two high-speed, 16550 compatible serial com-
munication ports (UARTs). Each UART includes a 16-byte send/receive FIFO,
a programmable baud rate generator, complete modem control capability and a
processor interrupt system. Both UARTs provide legacy speed with baud rate of
up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K,
or 1 Mb/s, which support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bidirectional Printer
Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Confi guration
