SMC FDC37C93XFR Super I/O Controller: Dell™ Dimension™ P133v, P166v, and P200v

Control for the integrated serial ports, parallel port, diskette drive, RTC, and keyboard controller is incorporated into a single component, the SMC FDC37C93XFR. This component provides:

• 2 NS16C550-compatible UARTs with send/receive 16-byte FIFO
  
  
• Multimode bidirectional parallel port
  
  
• Standard mode; IBM- and Centronics-compatible
  
  
• Enhanced Parallel Port (EPP) with BIOS/driver support
  
  
• High-speed mode; Extended Capabilities Port (ECP)-compatible
  
  
• Industry-standard diskette drive controller with 16-byte data FIFO (2.88-MB diskette drive support)
  
  
• Integrated RTC accurate within +/-13 min/yr
  
  
• Integrated keyboard/mouse controller
  
  
• Microsoft® Windows® 95-compliant

The FDC37C93XFR is normally configured automatically by the BIOS, but configuration of these interfaces also is possible using the CMOS Setup utility that can be invoked during system start-up. The serial port can be enabled as COM1, COM3, or disabled. The parallel port can be configured as compatible, bidirectional, ECP, or disabled. The diskette drive interface can be configured for 1.2-MB, 5.25-inch media or for 1.44-MB, 3.5-inch media. The ATX form factor eliminates the need for cables to parallel and serial ports by incorporating them on the system board, along with tidying up the cabling to diskette drive and EIDE devices through better placement of the diskette drive and EIDE headers.
